"When I travel, I love to check out yoga classes in new places, but using the used rented mats totally skeeves me out — as a yoga instructor I've seen far too much that I'd rather practice on the bare floor than down dog on a used mat! My solution is this Manduka Pro Travel Yoga Mat ($68). It's lightweight, foldable, and offers the tacky grip I love from my Manduka Pro mat. I'll either use it on its own or lay it on top of a borrowed studio mat for extra cushioning. — Jenny Sugar, staff writer, Fitness
