AirFlow Trunks 3.6" OpenFly – Silver Series, Yellow
Bright and performance-ready, these men’s boxer trunks in yellow offer ergonomic support and high breathability with a mid-rise fit and 3.6" inseam. Designed for active days, travel, and warm conditions.

A large anatomical pouch with a horizontal fly gives natural support, enhanced airflow, and fast access. Built-in support panels stabilize the anatomy and eliminate any pressure or discomfort.

The mesh gusset (92% polyester, 8% elastane) maximizes ventilation and moisture control, while the soft cotton-elastane body (95% cotton, 5% elastane) delivers all-day comfort and flexible fit. The lowered front reduces abdominal pressure and clean-cut leg hems stay in place without pinching. A soft 4 cm waistband ensures a firm and irritation-free hold.

Key Benefits:

Large anatomical pouch with horizontal fly – easy access and airflow
Mesh gusset – ventilated, cooling performance
Cools the body by up to 1.5°C – ideal for heat or motion
Breathable stretch fabric – premium alternative to ordinary cotton underwear
Mid-rise boxer trunks – 3.6" inseam, wide gusset for mobility
Clean-cut hems, soft waistband – comfort under any outfit

Part of the Silver Series, where minimalist design meets technical comfort. These yellow boxer trunks stand out in color and performance. A solid pick for those who want a combination of soft underwear, structure, and breathability. One of the best options when you want to buy men’s underwear that works as hard as you do.

Really like.

Awesome pair of boxers. Definitely need to order more

Comfortable, good fit but waist band tends to roll

Great fit, love the bright color

Bought for my husband, he asked for more 👍

Really comfy, love the bright yellow

Got these for my boyfriend, he’s hooked ❤️

Bought these for my husband for summer. He said they feel cool even when he’s outside working in the yard, and the color is surprisingly flattering. Shipping was quick and they came in nice packaging. 👍

Really light and supportive at the same time. I like the shorter leg for wearing under running shorts, doesn’t peak out or bunch. Yellow is fun and they haven’t stretched out after several washes.

Soft fabric, waistband doesn’t dig

Got these for my partner, he’s happy 😊

These fit exactly how I like—snug but not tight. Fabric breathes really well and the fly is easy to use. Great everyday pair for work and the gym.

Nice trunks, good for hot weather

Super light, feels great all day

Comfortable all day, no adjusting

Great quality. Great fit. I think going up one size would be beneficial. Make the pouch a little bigger.

Grabbed these for my partner and he immediately commented on how airy they feel. The yellow is bright but in a good way, kind of sporty. I’ve already ordered another pair in a different color. Packaging was nice too. He says they’re the only ones that don’t get sweaty when he’s outside with the kids, so that’s a win in my book.

Husband really likes these, looks great

Boyfriend says they’re crazy comfy 💯

Nice material, fly actually works well

Perfect under gym shorts, no lines

Breathes great, perfect under shorts

Super comfy, great everyday pair

My boyfriend looks amazing in these 🔥

These trunks surprised me with how light they feel. I barely notice them during the day, and the open fly works smoothly. Yellow color actually looks good against my skin tone.

Great ventilation, love the shorter leg

Bought for my boyfriend, he’s impressed 😊

Got these for my boyfriend and he immediately commented on how light they feel. The bright yellow looks really good on him and they don’t dig into his legs. I’m grabbing another color next order. ❤️

These are my go-to for the gym now. The front panel actually lets air in so I’m not soaked after cardio, and the shorter leg doesn’t creep up my thighs. Yellow ended up being more subtle than I thought.

Really comfy, worth the price

Nice snug fit, super breathable

Nice pair, waistband feels solid

Got these for my husband, he’s obsessed 💯

These stay cool even in my non-AC shop. The yellow is fun without looking silly, and the legs don’t bunch when I’m moving around. Definitely grabbing another pair.

Cool, light, fits true to size

Favorite trunks in my drawer now

My guy looks so good in these 🔥

Husband looks so good in these 😍

Got these for my husband, obsessed 😍

Boyfriend loves them, ordering more 👍

From the Founder of MAN’s SET

“Underwear shouldn’t make your body adapt to it — it should be designed around your body. That belief is what led us to create MAN’s SET anatomical underwear. Designed around the natural shape of the male body, it provides the space, support, and freedom of movement you need throughout the day. Because true comfort isn’t just about fabric — it starts with how underwear is designed. Once you experience the difference, ordinary underwear just doesn’t feel the same.”

WHY MAN's SET?

MAN's SET is designed to fit your body perfectly, supporting the natural position of your anatomy. The patented ball pouch, engineered for movement, eliminates chafing, adapts to your shape, and provides the precise support you need for any activity.
