Nice underwear - but extremely pricy!

 Rated 4.0 stars

From Michael

from Copenhagen, Denmark

I use the underwear for warm weather, when raining, for sports or just for everyday wear.

The only con for the item is the price. The price for a pair of boxers shouldn't exceed $10 US.

Perfect for shorts.

I got these to go with my shorts. The long version of these briefs, while great for pants, are long enough to be visible while wearing shorts. Naturally I do not want people being able to see my underwear while I'm working. Seems unprofessional and awkward at worst.

These briefs are a great improvement over anything else I've worn. If any one else has found something the works better keeping you "comfortable" all day. Please let me know. For right now, these are pretty much as good as it gets.

From SWThomas

from Okinawa

I really love these skivvies! I'm in the military and wanted something that breathes, whicks, and lasts, and these fit the bill. I use these every day over here in Afghanistan and also use them at home for recreation and casual activities. Plus, my wife thinks they're sexy when I'm walking around the house in them. Worth every penny!

these are much better than the under armour that I currently have. I wear these on 12 hour shifts in 85 degrees+ and they stay comfortable all day. Just bought 2 more pair.

I'm phasing out my old cotton underwear. Wearing these boys year round. They dry quickly while wearing after sweat-generating activities. Good moisture wicking. Comfortable as hell.

Love it

I bought a pair of these because of a friends recommendation. When I got them I couldn't believe how comfortable they were so I bought another pair the same day.

Best sports brief yet

Best Briefs Ever

 Rated 5.0 stars

From Big Al Island Boy

from Federal Way, WA

I have worn both Under Armor and Exoficio Briefs for the last five years. Both are really good but the 5.11 brief brings the best of both together to create the very best brief on earth.

Total comfort

 Rated 5.0 stars

From Dahigi

from East Coast Florida

I put them on mid evening when I received them, Slept in them, and then wore them all day in the 95 degree heat and 95 percent humidity in Florida, and let me tell you, these are the real deal... I couldn't believe how comfortable and good feeling they were. Awesome product and will be ordering more of them

Best briefs I've ever owned

 Rated 5.0 stars

From RM

from Los Angeles, CA

I admit, I'm a bit of a Nike snob when it comes to athletic gear. But I could never find athletic briefs that I was fully satisfied with. Whether it was Nike, or Under Armour, they either weren't cut right or the legs tended to ride up. I decided to try these 5.11 briefs, and now they're the only briefs I'll ever wear. Best briefs I've ever owned, hands down. I ended up purchasing a bunch to replace my other briefs.
