These are the most comfortable briefs! I would like to see them maybe .5” longer. Also Please make these in white…
I first purchase the sport which I found to be very comfortable however the medium inseam should be an additional ..5 inches . I purchased these because they were 3.6 but the material is a bit heavier. Please change the size of the sport and also offer them in white! I have white stretch jeans for summer and black shows through.you have all colors except white…why?
Bought these for my husband and he’s impressed. Says they stay cool and don’t ride up under his shorts. I love how the black looks on him, super clean and flattering. Might grab a few more pairs. ❤️
Really like these trunks. Lightweight, breathable, and the fly is actually easy to use. Waistband sits flat and they don’t dig in when I’m sitting at my desk all day.
Nice snug fit, but still breathable. The fabric is smooth, doesn’t chafe on long walks, and the open fly is actually practical. Might switch all my old underwear over to these.
Got these for my husband and he immediately asked me to order another couple pairs. They look sleek in black and the material feels really soft and airy in person.
My boyfriend says they’re crazy comfy
Great support, barely feel them on.
Got these for my boyfriend, he’s obsessed 💯
The shorter leg is perfect under my work shorts. They don’t ride up, even when I’m climbing in and out of the truck all day. Fabric feels smooth and keeps me from overheating.
Super light, feels like nothing on
Nice everyday black underwear
Breathable, comfy, great fit
Husband loves them, I love the view 😍
Didn’t think underwear could make such a difference, but here we are. These stay dry way longer than my old cotton ones and the shorter length doesn’t roll. I’ve already ordered more pairs in black. Packaging was simple, shipping quick, and the waistband hasn’t stretched out after several washes. Honestly forgetting I’m even wearing them most days.
Bought these for my husband, he loves how light they feel. The black looks sleek and I like how smooth the fabric is when I hug him. Definitely getting more colors next time. ❤️
Good pair, maybe runs a tad snug
Fits well, stays cool at work
Got these for my partner, no complaints 😊
Honestly forgot I had them on until I changed that night. The fabric is thin but still feels durable, and they dry super quick after workouts. I was skeptical about the open fly but it’s actually super convenient. Black color looks clean and minimal, which I prefer. Already eyeing a couple more pairs even at this price.
Good support without feeling bulky. I like the open fly for quick bathroom breaks at work, and the waistband sits flat and doesn’t dig in when I’m sitting.
Nice stretch, really breathable fabric
Good fit, open fly is handy.
My favorite black trunks now.
Got these for my husband, new fave ❤️
Solid fit, nice airflow
Super breathable boxers. I work long shifts on my feet and these keep everything cool and in place. Open fly works fine and the waistband doesn’t dig in at all.
Boyfriend said these are next-level comfy.
Got these for my boyfriend and he hasn’t stopped talking about how cool they feel. They make his butt look really good too. Ordering another pair so I can rotate them for him. 🔥
Crazy comfortable all day
Took a chance on these and I’m glad I did. Super lightweight but still supportive, and the fly makes bathroom breaks quicker. Black color goes with everything, so they’re my go-to now.
AirFlow Trunk 3.6” are genuinely comfortable in keeping my testicles away from my legs and providing a cool sensation. The only enhancement I would appreciate is a larger hanging compartment for my penis. Apart from that, I anticipate purchasing more of these in the future.
Comfortable, breathable, worth the money
Great everyday black trunks
Wasn’t sure about the shorter inseam but I’m glad I tried them. They don’t roll or bunch under jeans and the fabric keeps things dry even on hot days.
Boyfriend loves these on him 😍
Bought for my husband, he’s hooked 💯
Really like this pair. The shorter leg works great under my running shorts and the fly is easy to use. Black color hasn’t faded after a bunch of washes.
Solid trunks, worth the price.
