Review: I must say I like it - The size guide is accurate and they’re very comfortable
Review: Most comfortable underwear ever! - I never do product reviews, but i have to on this one. These underwear are amazing. They are soft and very stretchy so they comfortably conform to your body. Absolutely no wedgies even when exercising. The way the pockets cradle your junk is great. Keeps the twig and berries in front of you, no more in between your thighs. Added benefit is you get a rather impressive bulge to let people know their os something doen there. My girl said they are so hot 🔥 Good confidence booster. Also no more sticki g together or to your leg. Not enough good things to say about these. I am throwing away all my other underwear and buying a buch of these. Also, if you are in between sizes even a little bit go a size down. I always wore a medium but i got smalls on these and i am glad i did. They stretch so much that the small is perfect for me.

### ⭐⭐⭐⭐ Nice feel, no chafing and GREAT look
*by S***N on August 13, 2023*

I'd been looking to reduce chafing discomfort. These Sheath boxer briefs were the 3rd brand that I'd tried and I will definitely be buying more. Light while not feeling flimsy, with a dual pouch that is actually a dual pouch, preventing any chafing. These are a size smaller than I normally wear, but they are comfortable and not too tight; I would prefer a 3x be available, however, as I'm a big guy.
