I would like to buy more when they’re on sale for cheap.
I really do like the sheath underwear. 2 shorts in with this kind I’m reviewing. If you’re a man that needs a little more room sheath briefs will do. Like how everyone mentions that it’s easy to see the bulge. That’s the reason why I’d like the briefs a little bit more but these are good. They are very cozy. That’s why I keep buying more. The style is nice. The dual pouch works for me. The quality is good and the size is perfect. They do keep everything separated and I find myself adjusting less, which is good because I won’t look like a weirdo. The only only thing that’s a bummer is they don’t come in a three pack or two for cheap. I don’t find anything slipping out so that’s a plus. Overall, in summary, they are good and helpful when shaving down there nothing pricks you.

Very comfortable material, YOU DONT need to adjust anymore like a wierdo
It's an amazing pair of underwear. And that's the truth. Im actually rewriting this from before because I had time to wear them. I cant go back to my other underwear. I didn't even think of this till the 3rd time I wore them, but I never have to adjust myself with these underwear. I mean it still stands that you cant hide your morning wood but in my opinion its completely worth it. The material they use is really soft and hugs everything(thinking on getting the longer legged pair) you really are comfortable the whole day. And you also dont notice sweat nearly as much when everything is separated.m, and thats a huge positive. Especially for people who are active or work outside.

Very comfortable and supportive!
I did an overhaul of my underwear, replacing what I had with pairs of bower briefs and trunks that have a pouch and anatomical shape to offer more support. I'm very happy with the 2 pairs of Sheath I bought. The inseam was longer than 3" but not a deterrent for me. They are very comfortable. When first putting on I feel the supportiveness, but after a few minutes it just feels very natural. The waist feels a little looser than what I'm used to, so not sure if I would have to size down but everywhere else fits just fine. Definitely a unique design compared to some others I bought, but in a good way.

Best purchase I've made for my husband yet!
I got a pair of these for my husband while I was in Colorado visiting family. He is a picky guy, so I only got one pair. He absolutely LOVES them. The only reason I didn't give 5 stars is because I can't get more delivered to Turkey. So bummed.

Legit comfort!
I have had these on for all of 12 hours and I have never had a pair of underwear this perfect, they feel as close to cammando as I’ve ever had, no thigh stick, no jewel stick, and no d stick, just freedom in a sleek boxer brief

Pouch isn't deep enough for bigger guys
I'm still rating 5 stars, because it works as advertised and the material really breathes and feels really nice. Much nicer than normal underwear in the summer heat. However, as one reviewer already stated, if you're bigger, the pouch will indeed force your member to bend and curve as it's too shallow to hold all of it, resulting in a very noticable bulge. We're talking Chippendale model levels of bulge here. It is easily seen through basketball shorts or similar lightweight material, so do NOT wear these with anything like that, I took one look in the mirror and changed into normal boxers. Jeans and jean shorts are fine in my experience, they hold the bulge at bay and it's not that noticable from the side then. Also an important thing to note for the bigger guys that place your buddy to the right rather than left, your buddy will be seen through the fly and even pop out when bending. I'm lucky that I curve and place to the left, I read comments about this and tried to the right and confirmed it. BUT they make a version with a horizontal pouch, so I would search for that one instead if you curve right.

If 1 is good, does that mean 2 is better? Nope.
Pouch underwear has been around for many years, starting with King Style from China. That was and still is the most comfortable pouch, brief underwear even though you can't buy it anymore. Since then many version of the pouch have come to the market. Some are good, but this version 4.0 is not. The material is too soft and doesn't provide support, but my main complaint is the second pouch for the boys. It is uncomfortable and cuts underneath the scrotum. Having worn many versions of pouch underwear, the 2 pouch design is flawed. Secondly, the fly design is from the old, old jockey shorts; vertical slit on the right. No one ever gave any thought to left handed people. The best part of the King Style, Separatec design is the horizontal slit fly with the pouch that hold the man in place (and provides the comfort). Don't waste your money on this product; look at Separatec boxer briefs for the ultimate in comfort and support.
