Great question! We just launched a new product for that very problem. The Sticky Mat Towel, item 05-53141- it's a fast drying towel ideal for hot yoga and traditional practice. It fits directly on top of your yoga mat with a raised non-slip surface for perfect grip and an added hygienic surface. Another product that I recommend that you try are the 95-9196 Non slip Yoga Toe Sox.

The Stay Put Yoga Mat is meant to be used on the carpet because of it's non-slip backing, so this mat should work for you. The color is a muted red.
