Rated 5 out of 5 by from Best underwear I've worn The ExOfficio Give-N-Go Boxer Briefs are the most comfortable and functional underwear that I have ever worn. I bought these to use for backpacking because I was looking for one all-around pair to use that had the functionality of compression shorts without all that constriction up front. I used to wear Under Armor compression shorts while hiking/backpacking, but I would have to change into another pair of underwear to sleep in because it was too tight. Speaking of room up front, they are just right. I've actually started wearing them for everyday use because they are so comfortable. They are well worth the extra cost; you definitely get what you pay for.

Rated 5 out of 5 by from Best underwear for active men I have been wearing the Exofficio brand underwear for about a year and a half. I have about 8 pair now and still utilize the original pair that I purchased at the start. The small Exofficio imprint may wear off over time, but that is it. These underwear can take a beating: Running, hiking, weight lighting, working and playing with the children. They wash easily and sometimes on trips I simply wash them while showering and they are ready to go the next morning. Size runs a little big, so get a size down from normal. If you have never worn any, get 1 pair 1st to test size.

Rated 3 out of 5 by from Not sure why I have been buying these type of Boxer Briefs for years. REI brand, (2007ish) which were by far the most comfortable, until, for some UNKNOWN REASON, they changed fabric and cut...Never really good again. Tried every other Brand. For a while, the ExOfficio's ran a pretty close second. With the newest generation, I find it hard to find 2 pairs that fit exactly the same. I don't buy them online because of that. I go to the store and Compare, each pair. The Black colored, fit differently than the Gray. The Grays are baggy in the crouch. I currently have 4 pairs of each. wear them everyday.. Labels/Tags, really? Might be time to look elsewhere...... I never mind paying the premium price for something that works. For the price we pay, we should expect some quality control.

Rated 2 out of 5 by from Comfortable, but dye bled though hiking shorts I would like to give these an excellent because they are very comfortable even when soaked by rain all day, but their dye bled through and ruined the hiking shorts I was wearing. I prewashed the briefs before wearing. Then I wore them for 2 rainy days of backpacking. The dye in the shorts bled through the shorts ruining them. I have since washed them several more times and a test wash with a white handkerchief did not show any color loss so I am hopefully safe for future use. I would recommend several washings before you wear these shorts with lighter color pants/shorts.

Rated 5 out of 5 by from As great as they say, but run big As good as everyone says, but be aware, depending on your build, the sizes run big. I used to be a medium in everything and now apparently I'm a small and I haven't changed. I'm 5'11" and 155 lbs and 32" waist, last time I checked. And I ordered the mediums and they were way too big. Oh, and for those who say there's too much material and they ride up? It's because you did what I did and bought one size too big.

Rated 5 out of 5 by from Nothing between you & I but a thin layer of ExO... Sweet Fancy Moses! I have six pair. I used two pair exclusively on the Camino de Santiago in 2013. They are the best product on the market. By Far! I wear them daily as well as on adventures! I have large quads and they do not ride up my leg to create rub points. Again, they are the best product on the market!

Rated 5 out of 5 by from Strange Fit They don't have a defined cup that I am used to so they feel a bit strange when I am running. Other than that they are pretty great and I will probably buy another pair since they breath well and odor resistant.

Rated 1 out of 5 by from Poor design/fit I was told by everybody and their dog to buy these and am severely disappointed that I did. Maybe they were designed for perfectly flat stomachs and six packs and to come up to the belly button. If not, the crotch is extremely baggy and I'm really not sure how they calculate a 5.5" inseam, its 3" by my tape measure. I'm going to try to return and buy a medium (I'm a ~36" waist usually) and see if they are any better, but I don't really understand the popularity of these at all. I've also tried the REI brand and they are awful - bunching and riding up the legs is the primary problem.
