Towels are essential in a hot yoga class — well, if you don't want to be slipping and sliding around on your mat. Add the Yoga Jaci Yoga Mat Towel and Hand Towel Combo Set ($24) to your shopping cart. The towels, which have over 800 five-star reviews on Amazon, are made from a superabsorbent thin fabric that soaks up sweat, while staying put on your mat.
