Soft and snug

Chris N.January 4, 2026

Fit is great, could use a slightly bigger pouch. Fabric soft, straps sit well, waist band doesn’t fold. If not for the snugness upfront, I wouldn’t even know they were there. Read more

Pay attention to sizing.

AndyJanuary 24, 2025

These are really comfortable and look great. More for aesthetics than actually putting a cup in them because the strap is not as thick. I had to return the first pair because they were too big, so I’ll describe myself to help future buyers. The two straps in the back were loose and too big on XL and I have more than average curve around the backside. I’m 5’10” and between 170-175. Fit and athletic physique. The Large fit perfectly. Hope that helps. Definitely going to buy a few more pair for everyday wear. They really do look great. Read more

Blissful comfort

Christopher M.November 28, 2024

These are, by far, the most comfortable underwear I've ever owned. Finding such a piece has been a long struggle for me. My doctor told me years ago that I needed to wear a support garment for pain management reasons, but the ones that were supplied to me were the most uncomfortable, and not to mention ugly, things I've ever worn. Suffice to say that didn't last very long. I've worn everything from boxers to briefs to boxer briefs, none of which really offer that much support and just end up feeling restrictive. I've tried support thongs, which did offer good support, but I never enjoyed the strap of fabric up my crack. Then I tried these as a last resort, and they have completely changed my life. The pouch is sized just right to lift and cradle my genitals. The straps that go around and under the buttocks are of perfect length, thickness and elasticity. The waistband is also of perfect thickness, and does not dig into my hips like the wider, more traditional athletic supporters do. The fully open back allows complete freedom of access. These modern-style jockstraps are simply sublime, and feel like you are wearing nothing at all. The stretchy airmesh fabric moves with you and never feels binding or hindering. I loved the one I bought so much that I will soon be ordering half a dozen more in different colors. At this point I don't think I will ever wear anything else. Read more

Not For The Average Guy

craigDecember 20, 2024

Fit is very snug, digs into your skin, and is unattractive in my opinion. The cut is at least 1 size smaller, so order a larger size. Cost was fair, material was ok, looks much nicer in picture, shipping was delayed with Amazon. Breathable when exercising, support is loose, unless your King Kong. Not a good product for 2 or 3xl customers. Read more

Why didn’t I know

PhotoGraphicsJuly 7, 2023

We had over a thousand in my HS grad class, pretty large, but our gym class didn’t require jock straps, and our gym shorts were as short as it gets. That didn’t matter much because our swimming classes were totally au natural, so there weren’t any secrets anyway. I did try to get used to my first jock however and was discouraged that my most important parts felt squeezed in and packed down. Only recently did I try today’s updated version of this apparel. WHAT’S NEW The big difference with these Arjan Knos is just that, the pouch is realistically sized to hold me and what I’ve got with no shoehorn required. What I did like back then in gym, on me and the other guys, was the totally open back. I mean what’s it even there for in men’s underwear anyway, being enclosed in back has no practical function. Other than a more spacious pouch what makes these new ones is style, it’s important to me to make me feel good and for first impressions for the person lucky enough to slip them off me. SIZE Yes size is important. But buying underwear intended for the world market is a real challenge, the domestic size charts sometimes bear no resemblance to what I’m used to. I took a gamble with these and ordered three sizes up, expecting to get something that two of us could fit into. As suspected though these turned out to be just right around the waist, just right up front and there’s no back to even have a concern about. WHAT’S UNIQUE There are countless pages of listings for similar jocks, I chose these because of the open air netting on the front, it does its job as a bag for the goodies while letting them get plenty of air to retain a just showered freshness all day and into the night, sure to be appreciated by someone significant, who might even pause long enough to appreciate that they are semi see through for an advance peek at what’s to come. SO SO GOOD This part is minor, it has to do with the seams and straps. The straps on the back, thankfully, don't bury deep into my crack like thongs but they curl up and don't lay flat so with snug dress pants, where image is everything, they show an undesired panty line. The other minor issue is the seams, there is one right in the center of the pouch that presses against the entire length of my, er, thing and it's not the best feeling. YES NO MAYBE The reality is I’ve opted not to wear underwear most of my life since I still lived at home. About the only time it’s necessary is with today’s slim and stretchy dress pants, the stretch is what gives it away. So a jock to control the part of me that is uncontrollable works out good while an open back takes full advantage of looking good in those snug dress pants. So now these are the only kind of underwear I’m buying. These in particular have the right stuff - great colors, a stretchy pouch and an open air back. I like them. Read more
