A real treat.

Blending viscose from bamboo and stretchy spandex, the Saxx Ultra Boxer brief promises to be your new favorite underpants option. The highly breathable fabric allows air to flow through and wicks moisture to prevent things from getting swampy, and it's super-stretchy for total freedom of movement.

Sounds like these things rule.

  • Fit: True to size

I wouldn't know, obviously, but take it from my friend: "Best underwear ever. Hardly ever have to re-adjust with the ball-park pouch. No more leg stick!"

I will also add that, as a girl, I have literally never heard a single negative thing about Saxx underwear from any guy I've ever hung out with or dated. I also never thought I'd be writing this review...but these things work and you should probably snag yourself a pair (or several).

Who would have thunk?

I did not realize what I was missing until I started wearing Saxx underwear. Supportive, cool, and stylish for those that find it savy. As a lifelong cyclist that also rides the dirt jump bike and likes to play outside, these are my go to for a day at the jumps, everyday, and playing in the woods.

THE BEST

I absolutely love these boxers! So comfy and great quality

Under Where?

Who knew that a pair of boxes could accomplish so much with just a small tweak. The viscose fabric is soft to the touch and breath really well. Spending time in the desert definitely causes for some swampy conditions down below and I immediately noticed the difference from cotton or synthetic. The best part of these guys is the dividers that keep all the sheep in the same pasture ( if you catch my drift). If you have ever had a harness slip in the wrong spot or gotten some really uncomfy chafing from long hikes look to these guys to keep your nethers as comfy as the rest of your body.

Whoa.

I finally committed to a pair of Saxx and WHOA these are the real deal. So comfortable I want to live in them at all times. The fit is great and the fabric... well you just have to find out for yourself to really know.

These fit true to size, trust the size chart on this one.

What i know about the "Ultra" saxx is that its just the Vibe saxx but with a fly built in.

unusual and awesome

These are a very different feel, you'll have to wear them to know what I mean. but they have a very unique design that is unparalleled by an any other boxer manufacturer. give them a shot

So Soft and Comfy!

I got these as a gift and my boyfriend loves them. They have a super soft thin fabric. The elastic band is comfortable, not too tight and not too loose; just right. Fits true to size, got the color indigo and it looks exactly the same as the picture here on Backcountry.com.

After telling my brother and brother in law about how great these boxers are, I bought them each a pair. When I followed up with them too see what they thought, the answers were a mix of WOW, what have I been missing, and I'm never going back! Try a pair for yourself, you won't be disappointed. I find they run true to size.

These underwear live up to the hype. Super comfy and stylish.

Not sold on the hype just yet

    So I’ve heard these are amazing undies. I thought I’d try them out. They may be as amazing as people say. But I apparently got the wrong size. The chart on the product page wasn’t correct. Lately, I’m a 31-32 waist. I went with the medium as it said 32 was a medium. They fit in the waist band but are pretty loose elsewhere. So they don’t quite do their job. The fabric also bunches a bunch. I’ve attached the actual size chart from the back of the bock for your reference. I also didn’t realize they had the mesh panels in the pouch. I may be a fan of that detail. But again would be more effective if I had the correct size.

    Runs large, but very comfy

    • Familiarity: I've used it several times
    • Fit: Runs large

    They run a bit larger than other brands, but they are very soft and comfortable. The pouch is very nice. I will definitely purchase more pairs of saxx.

    Runs large

    • Fit: Runs large

    My own fault that I didn't check the size chart, but a medium fits more like a large from other clothing brands.

    Saxx are great

    • Familiarity: I've used it several times
    • Fit: True to size

    These are my favorite version of Saxx because they include a fly.

    Best boxer out

    • Familiarity: I've put it through the wringer

    Hands down the best boxers.

    Give your nethers a hug

    Like a La-Z-Boy recliner for your dangly bits... these are super comfy, cool, and breathable, and they keep everything in place.

    Great SAXX!

    • Familiarity: I've used it several times
    • Fit: True to size

    Very soft and comfy for your pride and joys. Not too baggy, but not too tight either!

    You Can't Go Wrong With These

    • Familiarity: I've used it several times
    • Fit: True to size

    These are by far the most comfortable boxer briefs I've owned. Get them.

    keep the boys in their room in comfort

    I love Saxx. I wear nothing but Saxx, although my favorite style is the Quest the Ultra is #2 slightly ahead of the Kinetic. the soft comfort of the Ultras is fantastic. They are butter soft and come in so many different colors its always fun browsing the patterns. If you don't buy the Quests get these, or better yet get both and some Kinetics and Vibes. Just do yourself a favor and get some Saxx ASAP! You will be thanking yourself immediately, except for the fact that you will have to replace all your underwear.

    Didn't care for them

      Fabric is nice and soft, however they started pilling quickly. I thought the concept would be great, but kind of just feels like underwear is always riding up...sizing was spot on though.
