Fastpacking enthusiasts require gear that can withstand challenging environments and keep up with their pace. To meet these needs, Microdose and Sealson Lab have collaborated to create the RB36 backpack.

Design and Features
The RB36 is designed by Microdose and engineered by Sealson lab, it features a 27L main compartment, side pockets that can hold 2L each, and a center pocket that can hold 5L, those are made out of Ultra Stretch™ for easy access and storage.

The backpack also features detachable 3M reflective shock compression cords and Daisy chain webbing for holding items trekking poles, ice axes, umbrellas etc...

Mobility and Accessibility
To enhance mobility, the RB36 backpack features shoulder straps designed as a vest silhouette, which is held by a 3M reflective shock cord, allowing for fast and easy movements. The shoulder straps are also made with 5mm EVA foam and feature quick-access and water bottle mesh pockets for each strap.

Materials and Build Quality
The RB36 backpack is made with high-quality materials, including Challenge UltraWeave™ 200 fabric, Ultra Stretch™ Mesh, and Tie-Dyed Nylon with a PU-Coating, which are ideal for fastpacking.

The UltraWeave™ is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to our revolutionary Challenge RUV™ film. The result is a textile that is incredibly strong, lightweight, and waterproof to 200 psi.

ULTRA™ performs in the harshest environments, in both sub-zero and tropical climates. The Ultra Stretch™ Mesh combines Ultra(UHMWPE) fibers with Nylon6-6 and spandex, providing exceptional flexibility. The Tie-Dyed Ripstop Nylon with PU-Coating is a high-performance fabric that is lightweight, comfortable, waterproof, and durable.

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
