I spend ALOT of time in the gym, running and biking too. I like all my clothes to fit well, look decent and function as intended. I have tried more athletic brands than I can list, from super cheap 'Old Navy' to way too expensive 'Hard Tail'. I was looking for long leg tights to wear to the gym and on my bike in cooler weather, I bought a few Danskin styles, O'neill, Champion and Spalding. All were returned except for these Danskin I'm reviewing and the O'neill (which are the bomb BTW, get them).
The Danskin are a heavier weight so if you don't wear undies, you can do a squat without horrifying people behind you. They also have a full gusset so they won't twist from side to side in the crotch area, they are fairly quick to dry and are supremely comfortable. The waist is regular, not low or high, legs are long enough for my 5'7 frame and they run very true to size. I weigh 165lbs, the large was perfect.  I bought other Danskin too, for some reason they just weren't as nice as these. Get them and do some squats, your butt will thank you.
