These things are great. The mesh material is cool and the nut cup technology is perfect. Waist band doesn't slip and the legs don't ride up. Important factors when you're 6ft 290lbs. Use the sizing chart before you order because it's pretty spot on.

I've been trying many different types of underwear and these are by far the best. I had tried some other David Archy and liked them except they were just a little short for me, causing some riding up. These are a touch longer, just enough that they don't bunch up, but not so long as to be uncomfortable. The material is great even on hot\sweaty days, and the cut\shape is much better than most others I tried

I think these are great. Keeps everything in place, does not ride up, and very durable. I wear these for running, spin class and bodyweight workouts and they perform well during all three. Not overly hot- a great base layer in warmer weather (under lightweight shorts) or in colder weather (under tights then heavier shorts.)
I am impressed and would reorder.

Great hiking underwear. Doesn't grab leg hair like some other, similar types have done. Would be functionally improved with a hole/fold in the front, but not hard to work around. Does fit...snug, but that was expected.

I have a few Tommy Johns, a few Exificio's and now 9 pair of David Archy. The other's are comfortable but the Tommy John's waist band rolls after a few weeks. The others are expensive so I decided to try something else. These David Archy's are super comfortable, and I like the pocket in the front. It cradles and separates better than the other brands.
Exificios and Tommy Johns cost as much as 3 pair of Archy's. The Archy's are light weight, flexible and since it gets very hot in south Texas, you need something that breaths and flexes when you are hiking or riding a bike. The wicking is as good as the other two but the comfort is somewhat better than them. My wallet feels better also since I got 9 pair for the price of three of the others.
