Very comfortable in all weather and activity level
As a well endowed guy these are the only underwear I've found that keeps me comfortable and everything in place. I wear them to work at a desk and to the gym or golf course. Equally effective in all instances all year round. They're the only underwear I buy anymore.

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.

Same factory as David Archy...
...makes Separatec. Exact same pattern. Material/fabric is the same, too. This style is great for base-ballers that need relief from chafing. Keeping your parts properly packaged is what this style is all about, while preserving ease of access and convenience. If you are a thinner build without junk in your trunk, the center panel can be removed, the new edges joined, and the fit is dramatically improved. A 5min fix at a machine, or a $3 alteration. I tried ordering a size smaller, but the pouch is relative and that made for a no-fit-fail. The front panel is made to accommodate guys who dress pointing up or down; plenty of room either way, while also allowing dress-left or dress-right. The fabric is very soft without feeling like polyester plastic. Comfy for foreskin; with or without. Xtra-Juicy guys will appreciate the absorbent flap that cradles the glans, still gives latitude when relocation to fresh fabric is necessary, and keeps willy from flying loose and banging his head against your zipper, et al. All-in-all these are great garments. Worth a try.

Separatec are one surprisingly fine brand of underwear!
These Separatec boxer-briefs are so perfect for me, not too tight nor loose, so comfortable what with that bamboo fabric, I've had a couple brands of briefs in the bamboo and they were really good (I especially liked Knitlord for the elastic being sewn into the fabric) but THESE ARE THE BEST! I live in a hot climate almost year round and coolness is my #1 factor, is why I was reluctant to get boxers, but they defeat the heat! Outstanding quality (has that high-end packaging & smell as if it's expensive sporting goods) and built-in holstering achievements (although sometimes shrinkage makes it not in use, the slight codpiece does not let on to that fact lol) make this a superb addition to my routine attire. Gonna get more soon! Highly recommend *****

Bottom line it rides up and the inseams rub causing irritation
My first introduction to Separatec was with the model pictured above (green) with the seams going across the leg. While that version did ride up like every boxer brief I've ever tried from any brand (Kirkland, CK, 2xist, Zombailon) it was so soft it didn't cause irritation plus I was use to ride up. My scrotum fit perfectly in the pocket as well as my other part in the other pocket. The first wear was very natural and I knew this was how I wanted my briefs going forward, but I didn't like the seams across the side. When I saw this new style (red) I thought it was the same but without the seams and I was excited. Once I got it I noticed the material felt softer and unfortunately that is where the pros stop for me. The issue is it rides up and rubs against the top of my scrotum so I'm not fitting in the pocket correctly and the seams the go along the sides of the scrotum are a little more rough. I lined it up with the other style and I was correct its actually smaller than the other style. I took a photo for others to see and determine if its right for them. I'm 6' 230lbs so I'm heavier set and while the overall size fits perfect, the narrower and shallower cut seems to be the difference why I dont fit in the pocket comfortably. My guess is for guys who are fit and in shape the difference in cut probably won't make a difference, but for heavier set guys its narrower and shorter than the other style pictured above will make it ride up and possibly rub creating discomfort like it did for me. It would be odd to try and return used underwear, but I think I might try an exchange and try their new omso tech material.

Ok so the ball park type pouches are everywhere these days. But you know the problem with those? In the heat Big Jim and The Twins just become one lump of sweaty mass stuffed in a pouch. Separatec solves this problem by placing Big Jim at one table and The Twins at their own booth. Leaving everyone more comfortable. The first time you put them on the may feel a bit foreign but within minutes of trying on your first pair you’ll be in love. I’m slowly replacing all my UA boxers with these.

I have several pairs of these. Put your package in place and you’re set for the day. If you walk around with these on your package will be on full display. Wife loves them!

ユニクロブリーフに比べると丈が短い。もう少し長い方が良かった。 履いた時にかなりモッコリ状態になるので、職場とかジムの更衣室のような、他の人が居る場所で着替えるのは恥ずかしさを感じる。 他の方のレビューにもあるように、竿用穴の位置が少し高いように思う。ボール用の膨らみがあるので、体とボールを分けてくれるのは良い。ただその分ボールを上げようとすると、竿用穴が上がってしまうので、竿自身としてはツライ体勢になってしまう。それを避けるため、竿は上向き、かつボールを押し上げる状態で履くようにしている。 いろいろ注文はあるが、かゆみを感じる回数は少なくなったし、良い商品だと思う。リピートする予定です。

After getting a size too large sent, these ones were great. Super comfy!
