Two Lululemon hot yoga mat/towel(s) designed to sit on top of your regular yoga mat to give you a non-slip, absorbent surface. One is grey the other is black. $25 each.

The other props are Halfmoon, brand new (no tags). Foam chips are $10 (new are $15), and the straps are $15 (new $20). I have more than are pictured here.
