CamelBak Kickbak Glacier 20 Ounce, 1 EA

This insulated vessel does triple-duty as a coffee mug, a water bottle, and a pint glass. The KickBak’s vacuum insulated, double-walled design keeps drinks cold for 8 hours and hot for 4. The lid is also designed to switch between hot and cold drinks: it flips back to offer small opening for sipping, and a larger one for chugging. Plus, it snaps easily into place to stay out of your way while you rink.
