## Description

Experience comfort and separation with our 7th-Gen Patented Dual Pouch Design, keeping your 'banana' and 'eggs' apart and preventing stickiness. Maintain hygiene and health with reduced bacterial growth, and enjoy a tagless, elastic waistband that won't irritate or pinch.

With a 3.5 inseam, it won't ride up, and its flattering fit hugs your thighs without restricting movement.

Review: Best Pouch Design - Though Size Matters... - I’d never found underwear I particularly liked and mostly put up with baggy boxers because all the other form fitting styles I tried didn’t have a functioning fly and/or were just too confining. Then I became intrigued by this separate pouch idea, with some hesitation from their unaccustomed revealing nature. That hesitation went away the moment I slipped them on. Why I Love This Design: I wasn’t seeking an artificial bulge and was quite pleased with how well their raised inner seam lifts the separate pouches to subtly accentuate size, shape and features, with an uncanny freedom of inside movement that doesn’t overtly add to the visibility outside. I wasn’t looking for athletic style support either, and was unsure of the boxer freedom I might be surrendering. What I found instead was an unconfined feel of things being comfortably in their place in a way that draws me back every day. Spontaneous occasions was not an expected review topic, but the difference with these is just too good to leave out. While some may object to the more confining nature of anything but boxers, it’s how these outer pouches proactively manages the occasion that really sets them apart. Being separated from leg openings is a welcome contrast to boxers that can hang you up or single pouches that squeeze you in. These are a generous pouch stretchiness instead that comfortably expands enough to maintain a least conspicuous relaxed position that virtually eliminates need for adjustment. Why Size Matters: What makes this design work as well as it can begins with the convex lower pouch that’s placed slightly above the body-hugging inseam to gently lift and pleasantly cradle things away from the legs. Next, everything is separated for a complimenting look and a freedom of movement not typically found with body hugging styles. The separate outer pouch fly acts more like a hood that’s easily slipped into and easily accessed by lifting the fabric end. All of this is then brought together with a proper match of their size to yours. Once size can’t fit all with most any pouch design though Separatic does offer some “larger pocket space” versions (as found on the item listing among dropdown photo descriptions to the left of the headline). The only size differences within a lineup then are waist sizes. While this works well for a fit within the lower pouch, accommodating the varied sizes inside the upper pouch becomes relative to how tightly or how loosely it's pulled against the body. Some snugness is always needed against the abdomen, rear and around the legs to avoid ride-up and wedging, and to keep everything in place. Too much snugness can cause cumbersome access and even squeeze you out of the fly, particularly when sitting down. Too loose compromises the form flattering upper pouch look, can get things lost fumbling through excess fabric and even allow things to fall through the lower pouch leg opening. To restate what the manufacturer mentions, the lineup size out-of-the-box should fit well for those midway in a size range, with a near average build and a near average relaxed length. For others, the fabric and waistband is stretchy enough to comfortably choose one waist size difference to accommodate a larger or smaller body build and/or relaxed length – particularly with the Separatec. With this slender frame reviewer, an in-between size 31” waist and average length meant that mediums always worn in other styles are a bit loose with the Separatec making a smaller size needed instead. If particularly endowed, it would be the mediums for the looser pouch. A larger build/relaxed length would have called for a size up – and so on. To that end, all should function ideally with a waist size snugness where a fully relaxed length end comfortably fills to a grazing of the pouch end. David Archy vs Separatec: Trying each product confirms other reviewer findings that the difference between brands is basically the fabric. With that, the thicker and less stretchy David Archy modal provides its subtle forward enhancement, with no conspicuous uncovering through even the thinnest suit or casual pants. Meanwhile the Separatac is all about a silky smooth stretchiness to allow a dual pouch following of the inner-thigh feel (and thinner pant reveal) of wearing nothing at all. I hope you found this review helpful.
Review: Front and center. Uniquely comfortable - All the positive reviews set very high expectations for me. When I first put these on, I did not immediately think that the Gates of Heaven had been opened. They were comfortable, but I didn't rank it as unbelievable. I did, however, pretty quickly realize they make you constantly aware of your manhood taking center stage. Literally, front and center at all times. It's a notable sensation of prominence. If you're accustomed to your member squished to the side, or pointing north, or twisted all around, these give you a very different vibe. My berries are larger than average, and their dedicated pouch is comfortable, much more lazy afternoon hammock than jockstrap restrictive. When I first looked at the member's only porthole, I was concerned it was going to give me a tourniquet kind of sensation. So far, that hasn't happened. I simultaneously feel free as a bird, but also safely confined to my nest. It wasn't until I went back to a pair of my previous drawers, Hollister boxer briefs, that I fully appreciated the Separatec design. Immediately the whole old school trio mishmash struck me as some uncontrolled chaos compared to the dual pouch separation. I realized how often manual adjustment is needed. The Hollister pouch design was a huge step up from any other brand that came before, but I think I'm now a full convert to the two pouches of Separatec. I will say the shorter trunks do ride up the leg a bit in the back but they are so thin and soft it really isn't noticeable even with pretty snug fitting pants. Still, my next order is for the longer leg boxer briefs plus a pack of the athletic briefs. I didn't realize until day two that there is actually an access port between the twig pouch and berry pouch for when you need to make water. Helpful. I can honestly say this is the priciest underwear I've ever purchased. But after trying the first 3-pack, the next orders were also the easiest underwear buying decision I ever made. FYI, my lady approved of the look and feel. Always a bonus. I'm a size 32-34 in pants, typically size medium in underwear. Separatec size medium was just right for me.

### ⭐⭐⭐⭐ Not too bad but not great
*by O***X on July 4, 2026*

These were pretty good for a while. They're made of a jersey like material that was passable but after a number of washes they got less comfortable. Sizing is spot on. Their newer products are much improved.
