You can't wear the shirt 'til you cross the finish line. And you can't cross the finish line if you don't train. Griffin's Trainer Plus armband is built to stay with you from training day to race day.

Trainer Plus starts with a wide armband that adjusts to fit arms up to 18 inches, and a velcro pull-tab that's easy to grip. Pocket and band are backed with sweat-wicking neoprene, allowing airflow to keep both you and your phone cool and comfortable. The transparent touch-through window allows full control of your touchscreen to adjust volume, navigate playlists, etc. A handy detachable cord wrap lets you keep your earbuds wrapped neatly, even when not in use.

Keep your iPhone protected no matter what the trail or road throws at you, with Trainer Plus.
