Editor's Pick: When you're too lazy to put together a top and bottom for the gym, just throw on this one piece and head out. The fabric wicks sweat and dries fast, so you won't feel sticky after a full round on the machines. The cut is fitted but not tight, and it barely rides up during squats or stretches. Pair it with sneakers and go straight from the gym to the grocery store, and it packs down small in your bag.
