PrAna Sutra Pant, $68. You may be tempted to walk out the door in your baggy old gray sweats, but try to resist: slightly tighter clothing allows an instructor to better adjust your pose so that you max out the benefits. These pants are stretchy enough to let you move, baggy enough that you don’t feel like you’re showing off too much, come in earthy colors and they’re made from hemp fibers which are naturally odor resistant.
