"Ever since I got a pair for a Christmas gift 8 years ago I have never worn anything else. They are super comfortable." Tony B.

"Why not wear a pair to shows off your personality? Aside from being incredibly comfortable, supportive, and breathable, BN3TH underwear also comes in some eye-catching patterns as well."

"BN3TH’s MyPakage Pouch Technology™ lifts & separates, eliminating the need to shift or adjust. This style will keep comfortable for full days equally on the mountain, on the water, in the gym or in the office."

"Built to keep your boys comfy, the 3-D pouch on these babies is one of-a-kind in comfort."

"...provides plenty of support to “keep your package secure in transit.” Made from a supple polyester-spandex blend, they provide temperature regulation and all-day dryness with a second-skin feel."

"...it eliminates the need for any the awkward gestures of shifting or adjusting, you know, down there, in public. Better yet, these boxer briefs are made with softer-than-cotton TENCEL™ Modal fibers that are gentle and breathable on the skin."

WHY MEN (AND WOMEN) LOVE BN3TH

The Perfect Gift

”The perfect gift for the boys who don’t know how great life can be. Making Christmas miracles happen! Thanks BN3TH!”
 
- Jamie D.

5 stars aren't enough

This is honestly some of the softest, most supportive, and generally best looking underwear I’ve had in a long long time. The fit and texture combine to create what is quite possibly the most comfortable pair of boxerbriefs that have ever existed.
 
- Connor C.

No going back

“Ever since I got a pair for a Christmas gift 8 years ago I have never worn anything else. They are super comfortable.”
 
Tony B.

Shopping for a man?

“Are you a man? Or are you someone who shops for a man? Buy these. My hubs is ecstatic about these underwear. He works outdoors in the heat and said when he wore them it was the most comfortable he’s ever been: no leg sticking, no having to readjust. He said all the junk fits nicely in the pouch.”
 
- Traci L.

Love these

I bought these for my husband. I love the different patterns and the way they look on him. He loves that they are so comfortable it feels like he has nothing on. He likes to lounge around the house in them. Ha Ha, fine by me.
 
- Christine P.

Wife loves them

“I never thought I'd buy pricey underwear, but these are just fit too good, last a long time (been using BN3TH for a few years now), and my wife likes them too...”
 
- John V.

For my boyfriend

“My boyfriend is a miner and often has little comforts to his days at work. He has expressed that these trunks are the softest!”
 
- Katarina R.

Perfect present

“Got my boyfriend flowers & wine for V Day…in the form of BN3TH. He loves wearing ‘em, I love seeing him in them…they’re the gift that keeps on giving for both of us.”
 
- Devon P.

FREQUENTLY ASKED QUESTIONS

How do the quantity discounts work?

When you spend a certain amount, you get an additional % off your entire order. Quantity discounts are applied at checkout.

WHAT MAKES BN3TH THE BEST GIFT EVER?

Our MyPakage Pouch Technology™ is a 3-dimensional pouch that lifts and supports the male package, separating it from the rest of the body. This differs from regular underwear that is 2-dimensional. The shape of the ‘pouch’ means that they eliminate skin-on-skin contact, so sweat and heat are reduced and chaffing is a thing of the past!
