These are light, breathable, flexible, and great for the gym.

He loves the comfort.

Nice fit, loose and very comfortable for sleeping

I'm 5'11, 180lbs, 8 body fat (very fit, and cyclist, so muscular legs/butt)I saw a slight tendency for people to rate this as too large so although Large would have been the sizing according to chart I ordered Medium.Well, even Medium was too large, and WAY too large. I can't imagine what Large would have been.I ended up ordering Small and it fits perfectly.My other body measurements are: waist=33, hips=37, inseam=31.5.In other words, if you're smaller or thinner than me there's no size for you because you would need some Extra-Small which doesn't exist at the time I write this review.If you get the sizing right, wow, these are really good. Fabric is light, smooth and flexible, you can do the splits with these no problem. The Stealth color looks much better IMO because you have that black line on the side, whereas the black is plain black.Also, the rope that comes is continuous so I cut it and burnt the two ends. I have no idea how anyone would tie a continuous rope :)

I can wear these for pajamas or to work out. They are soft, non-wrinkle and I can even wear these in summer.
