Zerofit Heatrub Ultimate Unisex Long Sleeve Base Layer TopOur most popular baselayer across the entire collection, the award winning Zerofit Heatrub Ultimate is a best in class, game changing baselayer that has been independently tested and proven to be five times warmer than leading competitors, and twice as warm as a sweater. Technologically enhanced 'Heat Threads inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly

Our most popular baselayer across the entire collection, the award-winning Zerofit Heatrub Ultimate is a best-in-class, game-changing baselayer that has been independently tested and proven to be five times warmer than leading competitors, and twice as warm as a sweater.

Technologically enhanced 'Heat Threads inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly and the construction of the Zerofit Heatrub Ultimate means the heat is retained.

Unlike other baselayers, the Ultimate does not work on the basis of 'compression for heat' - so not only does it provide greater warmth, but you also won’t feel restrained by an inability to move freely, making it one of our most comfortable baselayers.

It also features a slightly looser neckline design, which allows some heat to travel out away from the body - during testing and development of the Ultimate, a tighter neckline was found to cause some overheating.

A rigorous product evaluation at the iconic Boken Institute - Japan's leading testing organisation - resulted in a Heat Retention Rating of 0.78; a standard baselayer would have a rating of 0.1-0.14, while a sweater would typically have a rating of around 0.3.

Regardless of whether your passion is fishing, hiking, motorcycling, golf, equine sports, sailing, skiing, gardening or you spend a great deal of your working day outside – the Ultimate has got you covered in temperatures as low as minus 10° Celsius.

And because it's so good at keeping you warm, there's no need to 'layer up' with bulky additional clothing - the Ultimate does the work of multiple layers which also makes it a cost-effective heating solution.

PRODUCT BENEFITS

– Independently tested and proven to be five times warmer than a standard baselayer

– Instant heat the moment you put it on, doesn't require compression/tightness to keep you warm

Perfect for the aggressive chewer
Color: Purple
I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them! Keeps him occupied and satisfies his chewing for hours! And he leaves my shoes alone haha

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26

My pit bull loves them.
Color: Purple
I picked up the Frienhund Tough Dog Toys 3-pack for my large, heavy chewer, and overall I’m pretty impressed. Right out of the box, the toys feel solid and well-made—definitely more durable than your average chew toy. My dog usually destroys new toys within a day or two, but these have held up significantly longer, which is a big win. They also do a great job of keeping him occupied. The shapes and textures seem to keep his interest, and I’ve noticed less destructive chewing on furniture since introducing these. That alone makes them worth it. The only reason I’m giving 4 instead of 5 stars is that while they’re very tough, they’re not completely “indestructible” (despite the claim). After a couple of weeks of heavy use, there are some visible wear marks. Still, compared to most other toys we’ve tried, these last much longer. Overall, a great option for medium to large dogs that are aggressive chewers—durable, engaging, and a solid value for a 3-pack.

Great Toys for Chewers
Color: Purple
Love these dog toys, they are so well-made and keep my Golden Retriever busy for hours. The variety of sizes is nice too, they aren’t heavy at all, but they sure hold their shapes , even with the constant chewing. The price was very reasonable, too.
