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

unusual and awesome

  • Familiarity: I've put it through the wringer

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!

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: Medium

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.

    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!

    • 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.

      Thanks for contributing to the backcountry community, Brian.

      Only Choice

      I debated whether or not these would be worth it quite some time before pulling the trigger. I honestly wish I had sooner. By far the most comfortable and breathable boxers I've found to date.

      Saxx Ultra Boxer with Fly

        I now own six pairs of Saxx boxers: three Platinum and three Ultra. I honestly can't tell the difference between these and the Platinum boxers aside from the waistband, which has a sewn-on label instead of the Platinum's woven logo. They might be just a hair less soft, but only the proverbial pea-detecting princess would be able to tell the difference. That said, I love the way both versions feel and I highly endorse the design. Until something unsatisfactory crops up with these, I'll likely save a few bucks and buy Ultra instead of Platinum.

        Saxx briefs are always crazy comfortable, and I'm a big fan of the colors. My one complaint with these would be that the length is a bit longer than I would care for, however this is personal preference.

        Husband's new favs

        Saxx are my husband's new favorite skivvies - comfortable, look good, don't ride up and are breathable.

        Snazzy underpants!

        I snagged some of these Saxx Ultra Boxer Briefs for y husband because he wanted to step up his underwear game. He says they're super comfortable, supportive, and breathable. Definitely worth the investment!
