Even the most ardent minimalist will love the comfort and convenience that the Amphipod Profile Lite Trail Runner offers for long training runs. It includes two Hydraform water bottles with easy single handed access and Jett Squeeze caps for quick on the go drinking. The AirStretch waistbelt is breathable and moves with you for unrestricted mobility. An expandable main compartment stores your phone or snacks, and zippered cargo pockets hold keys, cash, or energy gels. The stretchy external bungee lets you stash a rain jacket or extra layer when the weather isn't cooperating. Plus, the pack's smart design ensures it won't bounce or throw you off balance while you run.
