Has what I'm looking for in a good racing/interval shorts... split seam, crepe liner, sturdy drawstring, key pocket, and of course, black color. I like the waistband of these shorts in particular, which seems to be a tiny bit wider than that in the equivalent shorts made by Asics, Brooks, and Mizuno (also great shorts, incidentally)
Rides up a tiny bit, but not enough to be a bother. Material is a little...silkier...than I'm used to, but some people might like that. Good price. Only other running underwear I've found that I like more (for a reasonable price) is the Asics ASX bikini.
Not too expensive in price, but not too cheap in quality, either. I like that it has two brightness settings. Haven't used it for extended periods of time outdoors yet, but it seems like a good entry-level lamp.
So...I'm a fairly small person (5'1"-ish and slight-to-medium build. I'm Asian, if that helps.) Normally, I wear a small for t-shirts, maybe a medium if it's a women's/athletic cut shirt. I ordered a medium and it was a bit tighter than I like, but workable. Then I put it in the dryer...on WARM (and the dryer in my dorm is not very warm...half the time my clothes don't even come out dry). The shirt came out significantly shrunk, particularly in the shoulders.
Moral? Buy at LEAST one size up, maybe two if you're not sure/have a warm dryer/have muscle-y shoulders :)
