To get started
You'll want to attach rigging to 6 to 7 locations on the bivy: top corners of the tub (4), apexes (2), middle of ridge (1)(optional).
Included: 18 ft of 1/16" shock cord, 7 mitten hooks, 3 mini barrel cordlocks
If pitching with a YAMA tarp or the stand-alone rigging kit, please see the following chart for suggested cord lengths:
For current bivy version: Coming*
For older chest or ridge zip bivys: Cord length chart
*For connecting the newer bivy to a 1P Cirriform Tarp tentative lengths follow: Front corners: 22", Rear corners: 14", Front apex: 28", Rear apex: 23", Center of ridge: 13" (you may wish to cut these a little longer and trim as needed)
To install the cords:
You don’t need to follow our method, but this is how we like to do it.
At the corners
- Tie a loop on one end of the shock cord. We like to use a simple overhand loop knot.
- Using a clinch knot, tie on a mitten hook to the other end of the cord.
- Attach the cord to the tub with a girth hitch.
At the apexes
- Tie a loop on one end of the shock cord using an overhand loop knot.
- Pass the cord through a cord lock.
- Pass the free end of the cord through the small webbing loop at the apex (direction: middle of bivy outward).
At the front, two webbing loops are provided, one on either side of the zipper. Pass the cord through the loop on the side opposite the side you'd like to bivy to open towards.) - Using a clinch knot, tie on a mitten hook to the free end of the cord.
At the middle of the ridge
(Optional. Connecting the this location to a point above can help to open up the inside of the bivy)
- Tie a loop on one end of the shock cord using an overhand loop knot.
- Pass the cord through a cord lock.
- Pass the free end of the cord through the small webbing loop at the apex.
- Using a clinch knot, tie on a mitten hook to the free end of the cord.
Stand-alone rigging kit:
For pitching the bivy on its own, we also offer a stand-alone rigging kit. This lightweight kit allows you to pitch the bivy with your poles and just four stakes. Please see the rigging kit's page for more information and instructions.

Salivea works well
Size: 1 Ounce (Pack of 1)
Following throat radiation I had dry mouth. The dentist recommended Salivea. I apply it right before I go to bed. It worked well. This is the 2nd tube I have purchased.

A treasure: surprisingly easy read for being so well researched and referenced
Format: Paperback
was recommended by Chris Kresser (Healthy Sceptic blog). I admit I was skeptical: the titel, at first glance, comes across as pretentious, and the front page has a weird 80s feel to it. Anyway, Chris knows his stuff, so I bought it.
The PHD book is priceless. Yes, this is the best book about diet. I had been on a Paleo diet for a month when I got the book. I was motivated to change my diet, but after reading the book, first quickly once, and then more carefully a second time, I was even more motivated. I was convinced that I had to make a change for life.
Other reviewers have summarized the contents well, so I will not. Eliminate processed foods, grains (except rice), legumes and most sugars. Stick to high fat diary. Bottom line in terms of macronutrient ratios is: not too much carbs, plenty of good fats, and ideally some protein restriction.
I believe better authors could not have been found. Even though Shou-Ching Jaminet is a cancer researcher, none of them came to this from a medical or nutrition background, which is probably an advantage. They have experienced chronic disease themselves, and were committed to find solutions and understand pathways that were not well understood. They have enormous intellectual capacity (scrutinizing studies from PubMed the way they do is, well, impressive). They are open minded. And, not the least, I think they are driven by not only intellectual curiosity, but alturism, which, gives the whole project a very humane and caring feel to it.
What is the difference between this diet and the Paleo diet?
There are many variations of the Paleo diet, but Cordain at least recommends lean meats, which is the opposite of what the PHD recommends. The PHD "allows" full fat diary and rice, which is not recommended by most other Paleo diets. The PHD also has a rather specific macronutrient ratio recommendation.
The results?
Well, I started on a Paleo / GAPS protocol about a month before I got this book, so I cannot really say that all the improvements I have had can be attributed to this book. And after 48 hours without any processed foods, grains, legumes, sugar (apart from low carb from starches) and diary, I went from standing, sitting and walking with great joint pain, to only slight pain. A skin condition I had improved as well.
Two weeks after I got the book, I tried using almost only rice as my carbohydrate source for 10 days. That increased my joint pain slightly. I think I in any case might have been in the high range of the carbohydrate intake during this period, which might be the reason for the change to the worse, rather than the type of starch I ate. The other thing though, is that once I started eating rice, and maybe too generous portions, my carb cravings were significantly elevated. I will try to stick mostly to sweet potatoes, taro, pumpkin, carrots, zucchini, berries and fruits (in the morning) for carbs.
I have started implementing their supplement regime. I was skeptical at first, because, like many people, I prefer getting micronutrients from food, not supplements. But I decided to try since I had some heath issues and blood panel results that had to be improved. After about two weeks, I feel a bit better. I have a bit more energy and my head feels clearer.
Am I skeptical to anything? Not much.
- As I said, they convinced me to try their supplement regime and I do not regret it. I think anyone with an autoimmune condition, chronic disease - even a suspected chronic infection - should do so. For those who are fortunate to be 100% healthy and full of energy, well, maybe they do not need to take all the supplements if the diet is very dialed in.
- At first I thought the macronutrient ratios were a bit too rigid. After reading the book a second time, I felt they presented a convincing argument. I will never weigh and measure my food, so I do not know exactly what my macro ratios look like, but the book provides very useful guidance.
- Then, rice. I would have liked to see a bit more on why they think rice is a "safe" grain. Also, since it is not very nutrient dense, I think it gets a bit too much favorable mention. Eating food with low nutrient density and then taking lots of supplements does not sound like a perfect health diet. But this is a detail - people do not have to eat a lot of rice on this diet, and it is good to know that it is pretty okay to eat it from time to time.
I have used their blog a lot, for tweaking my supplement regime, for recipes etc. It is an excellent companion to the book.
For the next edition, I have the following wishes:
- An index
- Improvements in lay-out (sorry, but it is incredibly ugly): margins needed, footnotes can be smaller, table of contents more reader friendly etc.
- A chapter with summary recommendations for common autoimmune conditions and chronic infections.
- A bit more info on diary. Why high fat diary is okay for most people, and for what conditions diary should be eliminated completely (and why).
Conclusion:
I honestly think this book is such a treasure. I have translated and adapted the main recommendations into my native language for my family. It is difficult to persuade anyone about diet, but it is difficult not to try with people you really love. I do not doubt for a second that following the recommendations contained in this book can go a long way in reversing, even curing diseases, and definitely preventing diseases. I feel very grateful to Paul and Shou-Ching Jaminet. Thank you.

Changed My Life
Format: Hardcover
The year the Green Bay Packers drafted BJ Raji I remember being extremely shocked that I weighed almost the same as him (319 was my peak). Winter of 2009 I started riding a stationary bike fairly regularly, Spring of 2010 I started bike commuting regularly and by summer of 2012 I was down 60 pounds.
As I became more interested in fitness I was more interested in how the body handled different kinds of macro nutrients. I did a few random Google searches for a book on the topic and in June of 2012 I found a review of the original PHD edition which made it sound like what I wanted. I wasn't looking to change my diet, I had a lot of joint pain and was very susceptible to binge eating/drinking, but I was loosing weight so overall I was happy.
I remember reading the first chapter where it explained the "gotchyas" like having to give up wheat and laughing out loud at the though of it. I was a complete carb fiend to the point where I'd been baking my own homemade artisan breads.
I found the book to be a quick read, it took me only a week. I definitely went a bit cross eyed at some of the more complex biology, but overall I found it as entertaining as it was informative, and when I'd finished I thought "What the hell", I'll try it for a week or two and see what happens.
My first weekend was a little rough because I went out with some friends and because bar we were at only had fried foods, I ended up drinking way too much on an empty stomach. My first attempt at baking salmon the next day was promptly thrown up, but fortunately it didn't give me a bad taste for the fish.
In only a few days I started to notice how different being hungry felt. I'd always made it a point to have breakfast and not eat again until Lunch, but I usually had a few spikes of intense hunter which I had to fight past. On this diet the hunger was there but it was more of a casual suggestion.
Needless to say I had such an easy time on my two week trial that I kept the diet. That summer I lost as much weight as I had the previous two combined. I feel much more even in terms of mood, my mind feels sharper, I have a nice even energy level all day. I had hoped my joint pain would clear up faster, but it has definitely gotten better as well.
I'd been wanting to reread the PHD for a while, but I knew the new edition was coming out soon so I held off. I was aware of some of the changes from following the blog (which is excellent, it's such a trip to have Paul give expert answers to your questions personally), but still wanted to go through the whole thing again.
The new version is a definite improvement. Like I'd mentioned some of the biology in the original edition, particularly on the different types of fats, came early and confused and discouraged me a bit. This version they hook you in with simpler explanations and do a better job of building up the biology as you go.
Also after the original edition I had to do a lot of fine tuning to the diet based on questions I'd ask Paul on blog, or going back and reading other peoples questions. In this edition they do a much better job of practically spelling out things so its easier to jump in.
Finally the reader results that are included in the new edition are a really neat addition. I'd read a lot of them on the blog as well, but they're so amazing and inspiring, sprinkling them into the text the way they did was a really great idea.
After finishing this new edition I feel freshly excited about a diet I've been on for half a year. I also feel better about recommending this edition to friends because it reads so much easier.
I highly recommend this book to anyone looking to gain health, loose weight, or even just learn about how their bodies work.

I can't believe how much better I feel!
Format: Paperback
I had been eating (very) low-carb and high-protein for the better part of a decade - and I had gotten a lot of practice arrogantly dismissing suggestions (from any source) that I should change anything about my diet.
It is a testimony to the insightfulness of this book that it persuaded me to change.
How was I persuaded?
* The Jaminets are highly educated (Ph.D.s both), but not they're not nutritionists and are not bound by any party line.
* They amass a huge volume of scientific literature in support of their assertions - about 1/3 of every page is journal citations.
* They write clearly, and are clearly motivated by a desire to share the keys they've discovered for better health.
* Time after time, while reading, I exclaimed "so *that's* why!" - there's an overarching framework they build, and after reading it I have a much broader and deeper understanding of health and nutrition.
The changes I made were:
1. Eat a modest amount (15-20%) of calories as carbs from what they call "safe starches" (rice & potatoes in my case.)
2. Eat a large (~70%) of calories from fat. In particular, I consume dramatically more butter (kerrygold!), and I've added a fair bit of coconut oil too.
3. (As a result, the amount of protein I eat has dropped somewhat.)
4. Supplementing with a mix of the vitamins they recommend.
5. Doing a 24-hour fast once a week.
Results: (after 1.5 months or so.)
1. I'm no longer "brain-dead" and unable to think in the evenings after work.
2. I no longer have fruit or chocolate cravings.
3. I'm much happier, and wake up looking forward to the day.
4. I've been much more social.
5. The extra starch has not resulted in weight gain. (I always gained weight when eating carbs before.)
6. It looks like the fasting (which I've never tried before) is helping my alertness and also contributing to healthy weight loss.
It took less than a week for me to notice dramatic changes. The diet guidelines are straightforward and fit on a page, but the explanatory material is priceless. The Jaminets post on an ongoing basis at their perfecthealthdiet dot com blog as well.
I can't recommend this book highly enough.

Best diet/health book I have ever read
Format: Kindle
For scientifically-minded laypeople, this is an excellent read. I altered my diet because of this book. Using a bit of intuition, it seems much more logical that nature attempts to achieve balance with respect to macro nutrients and vitamins/minerals. I loved Mr. Jaminet's explanation of the relationship of vitamin A,D, and K. I do have about a thousand questions for the author (Paul Jaminet), such as his lower protein recommendations (this differs greatly from a typical gym rat's recommendation of 1 gram of protein per pound of body mass). The book recommends more protein for the athlete, but not at the levels recommended elsewhere (high protein diets). I think Mr. Jaminet and others that are recommending a smaller ratio of protein to fat/carbs are ahead of the game. I find my diet in desperate need of more insoluble fiber, although this book does not treat fiber as being extremely important and advises against too much fiber. I use PGX daily fiber once per day and it had made a big difference for me. All in all, there are 3 big aspects that I would like Mr. Jaminet to weigh in on in future books or other publications. First, please expand more on repairing the health of your gut and the good bacteria that live there. What is the absolute quickest way to optimize gut flora and, subsequently, keep inflammation at a minimum? I understand Mr. Jaminet's stance on legumes, but it seems very contradictory to common sense. From the surface, not eating any legumes would raise my BS flag. Overall, if the answer is "don't eat legumes because you can get all the benefits from other foods and, therefore, better safe than sorry", then this should be considered a dubious argument (I am not saying that this is the argument in the book). To be fair, the book has much more detailed reasons to steer clear of legumes, but I am still a little on the fence about it. Lastly, PHD refers to the Shangri-la diet and using MCT or Coconut oil to suppress appetite, but I would LOVE a detailed scientific explanation of what the body's "setpoint" really is. From my clinical trials (on myself!), this is a huge factor. My body seems to want to be at a set weight and even body fat percentage and it takes quite a bit of effort to lower or raise that setpoint. This applies to the PHD because assertions are made with respect to the body's need for a certain quantity of protein and carbs. How does the setpoint interact with those processes?
PROS:
* Clearly, Mr. Jaminet or his editors took a technical writing course. This book is written using the active voice and uses a conversational tone. Extremely easy to read! It is simple, direct, clear, and concise.
CONS:
* This book cites clinical studies as evidence to buttress certain assertions. This is not a problem if you factor in what the study was trying to measure and external variables that would greatly affect the conclusions. Here is an example of clinical studies that are almost worthless (at least from drawing a single conclusion): Patient group A ate such and such and patient group B ate such and such over a 20 year period. The death rate was 11% higher in patient group A, therefore eating what they ate "may" have been the cause of the higher death rate. Drawing conclusions from such a study is really difficult, I think. I am no scientist, but even I can see that these sorts of studies should be used as a starting point for more investigation and not as the final word on a subject.
