Nylon 9in Boxer Briefs No Fly 4pk Black/Dark Blue/Gray/Light Blue

They feel amazing. Wear at gym. Great for leg day; squats, leg curls/extensions, adductors/abductors, press. Also great for treadmill warm up. Keeps everything out of the way and in the right place. Highly recommend.

Fits great and I didn't know it wasn't good to dry underwear until now and think they'll last a while. Beyond satisfied!

Best underwear ever. Why did men wait so long to make custom fit underwear for ourselves? Life changing.
