Nike
Mens Pro BaseLayer Shorts 7 Inch

I wear these more and more and am finding that my hamstrings are better for it.
I have 2 pairs and will probably buy another in due course.

My go to for training shorts. Very comfortable, sweat wicking, and holds your stuff in place.

Ive got a couple of pairs of these but my glutes are huge now so had to buy some more one size up. I'm a 32" waist, normally a small would be fine. Size up if you've got large legs/butt.
