CGear Sand-Free Technology, $60. This under-your-yoga-mat mat was designed with military anti-sand technology—it allows sand and dirt to move from the top of the mat through to the ground, but won’t let a speck come back onto its surface. This means you’re free to take the route of your wife and head to the beach for morning sun salutations or hike your moves into the dusty wild on your connect-with-nature camping trip without having to worry about ruining your yoga gear. Bonus: Throw it under your tent or use it for sitting to keep your other gear sand- and dirt-free.
