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 armband is built to go all the way with you from training day to race day.
Trainer starts with a wide, stretch armband that adjusts to fit arms up to 18 inches around. A slide-ring adjusts for a perfect fit, then holds it in place.
Trainer holds your iPhone in a lightweight pocket, perforated and backed with sweat-wicking neoprene to allow airflow that keeps things cool and comfortable. The case's touch-through window for your touchscreen is as transparent to your fingers as it is to your eyes, so you can adjust volume, navigate playlists, etc., with ease, without takiing your phone out of the case.
Keep your iPhone protected no matter what the trail or road throws at you, with a Trainer armband from Griffin.
