No matter what your workout looks like, the last thing on your mind should be a leaky water bottle with a bulky shape and no insulation. Meet the Nike Recharge bottle: a bottle made with a tough workout in mind. The durable stainless steel design is vacuum-insulated to keep liquids cold, and the ergonomic shape is easy to hold. Toss it in your gym bag and head out—its leak-resistant lid helps add a tight seal no matter where you go.
