Customer photo review of ProActive Soft Boxer Brief 5.8", Forest Green

I absolutely love the waist and leg fitting. I have the XXL and being a big guy my only concern is that the junk drawer is restrictive. If the tool pouch was 25% bigger, the wearing experience would be awesome for over all activities. I enjoy working out and stuff and they are not the most accommodating for working out.

ProActive Soft Boxer Brief 5.8", Forest Green

I bought one and wore it all day and night. Comfortable and keeps my junk in a junk bag with adjustable pull. But no problem with normal activities like using the urinal. I wore them for a long treadmill session and strength training. Good fit and no rubbing. They are cotton so sweat gets them wet. So you need to put on a dry pair after showering but that’s fine. Being 95% cotton, and so more healthy, was what I wanted. I ordered 5 more.

ProActive Soft Boxer Brief 5.8″, Forest Green

The pouch is very nice and fabric is comfortable. The only problem, it doesn't accommodate my length. If it had a bit more room length wise, it would be absolutely perfect.

ProActive Soft Boxer Brief 5.8″, Forest Green

They fit great but ever since washing them they are a little tight. I’m also not sure why there is a pull tab between the legs. It makes it uncomfortable.

ProActive Soft Boxer Brief 5.8", Forest Green

Extremely comfortable. This does what is advertised they do separate you junk fantastically. In my opinion a little heavy for summer wear. If they could be made with a lightweight fabric for summer heat they would be perfect.

ProActive Soft Boxer Brief 5.8", Forest Green

Honestly some of the best-fitting underwear I’ve owned. The fabric is super soft but still supportive, and the legs don’t creep up when I’m lifting or running errands. The green color is low-key but looks sharp. I’ve washed them a handful of times and the waistband hasn’t twisted or loosened at all. Already thinking about replacing a bunch of my old pairs with more like this.

ProActive Soft Boxer Brief 5.8", Forest Green

Got these for my boyfriend and he immediately tossed on this pair. He said the fit was perfect and liked that the legs didn’t roll up under his jeans. The green looks really handsome on him too. After washing a few times they still feel soft and haven’t shrunk. I’m planning to grab another couple colors for him soon. 👍

ProActive Soft Boxer Brief 5.8", Forest Green

Picked these up on a whim to try something softer than my usual packs. The first thing I noticed was how smooth the fabric felt pulling them on, almost like there’s no seams. The legs stay put when I’m climbing stairs or squatting at the gym, which is huge for me. The green color is actually pretty subtle in person, not loud at all. I’ve washed them a few times now and there’s no shrinking or twisting at the waistband. Honestly didn’t expect to care about underwear this much, but I’m slowly swapping out my old stuff with these.

ProActive Soft Boxer Brief 5.8", Forest Green

Wasn’t sure about the price but I get it now. These feel way nicer than my usual packs and the support up front is perfect. The green is a cool change from basic black or gray.

ProActive Soft Boxer Brief 5.8", Forest Green

These feel way nicer than my usual cotton multipacks. The material is smooth and doesn’t get swampy during long days. Legs stay in place and the pouch has just enough room.

ProActive Soft Boxer Brief 5.8", Forest Green

Bought these for my boyfriend and he said they’re the softest ones in his drawer now. The green is subtle but really flattering. Shipping was quick too, which I appreciated.

ProActive Soft Boxer Brief 5.8", Forest Green

Didn’t think I’d care about color, but the deep green on these is actually pretty slick in person. Fabric’s soft but not flimsy, and they don’t sag by the end of the day. Wore them through a full work shift and then to the gym with zero adjusting. Waistband stays flat and doesn’t dig in when I’m sitting. Honestly feels like a big upgrade from the bulk packs I usually buy at the big box stores.

ProActive Soft Boxer Brief 5.8", Forest Green

Really happy with this underwear. The legs stay put when I’m biking to work and the waistband doesn’t roll or pinch. Color looks solid and they’ve held up fine after several washes.

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.
