They work.
I saw these on a sponsor ad section on a couple of Youtube videos (one of Simon Whistler's many channels) and half-remembered it afterwards. I thought it sounded like a gimmick for selling overpriced underwear. I work some long shifts in a fairly hot environment, which gets uncomfortable. Trips to the toilet to unpeel my scrotum from my thigh and wipe the sweat off. Itchy. Not ideal. So I thought I'd give these a try, despite expecting them to be gimmicky nonsense. They're not gimmicky nonsense. They work as described. Good support (which I appreciate more as I get older and saggier) and no more sweaty scrotum. The only drawback is the price. I'd like a dozen pairs, but I balk at spending £300+ on underpants.

Worth Every Penny!
So pleased with these, I now have 11 pairs. Well worth the investment, and standing up well to wear and washing.

Poor quality
Quality is pretty. Mine came already with bad quality. I read other reviews they have serious quality issues, mainly after using a few times. And is too expensive for not having a good quality.

Great no more binding jumping in and out of the saddle.

Very very comfortable
Loved the fit of the underwear and the the feeling of good separation and sweat control after a very physical 8 hour shift

Sólo buen diseño
Buen diseño. Pero ... soy talla 30 , compre talla chica supuestamente para cinturas de 28 a 30... Y el boxers me quedo algo flojo.. no hace fit en mi. Antes de que me llegará el producto intenté contactarme con el vendedor dos veces , por medio de la app y por medio de servicio al cliente de amazon y en ni uno de los casos contestó. El producto hubiera sido excelente si tubieran los tamaños adecuados a las medidas que dice el boxer u ordenadas.

These are the most comfortable, smartest boxer briefs I have ever worn!
These are AWESOME! I just got them, and I changed into them from my favorite brand of boxer briefs as soon as they arrived. The fit is perfect, and the inner pouch along with the other opening for your junk keeps everything separated and comfy. No binding when sitting down or stooping, and they keep the boys from sticking to your thighs. They are made of a stretchy, wicking material and feel great. The waistband so far is not doing any rollovers, and the leg openings are staying put. These are expensive, but worth every penny. I will need to have a week's worth of these on hand! STRONGLY recommend. I wish the makers would send me a complimentary pair! EDIT: Okay, I am still in love with these boxer briefs. I have now washed them at least a dozen times, and they look and feel and fit exactly the same as they did when I bought them! This means that there will not be the stretched out waistband, raggedy edges or tiny holes which form in cotton boxer briefs. I will be purchasing more Sheath underwear, but now am curious about the 4.0 version.

Sexy and comfortable!!
Not only are SHEATH SEXY but the material is soft to the touch and breathable. They fit my husband perfectly in all the right places. Keeps his bits dry and separated, no more doing the sweat squats! This isn't his first pair of SHEATH 3.21 mens boxer briefs, I'm a return costumer. These boxers aren't just appreciated by men.
