Everyone has that friend–the one that squeezes in a visit to the gym like it’s a trip to the bathroom. Since they clearly don’t need a gym membership, this exercise-friendly Belkin FastFit case will make their workouts a bit more musical. The arm band is soft and adjustable and comes with a cable capsule to neatly store headphones. Runners will appreciate the waterproof material and reflective stripe for nighttime jogs. A built-in screen cover ensures protection from the elements but also makes for easy navigation. (Clearly our model needs that gym membership.)
