## Description

With the SHEATH 3.0 Zen, we decided to take what makes SHEATH Underwear so great and give it an extra dimension of luxury. Created with an exquisite blend of 95% Modal and 5% Elastane, this model seamlessly combines functionality and elegance. The silky, yet elastic and breathable feel of the 3.0 combined with the wide aztec geometric waistband (courtesy of our friends at TIMEWHEEL) really places this model into a category of its own in terms of style and comfort.

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