LOTS of compression.
Long length.
Great wicking material.
Look great.
NOT see-through even when bending/squatting.
Small key pocket in the waistband.
They don't slip down during your workout.
These are leggings for someone who is serious about working out. Use the size chart, size up if you aren't sure. I usually wear a L in leggings, I got an XL in these.
I have four pair, different patterns, love them all. The blue flower leggings have a little less compression, but the b/w and w/b tangled, and the camo leggings REALLY hold you in.
Definitely in the favorite pile in my leggings drawer!
