In hues inspired by nature, the Sierra Sport Canteen is the perfect companion for your workouts. Holding a generous 20 ounces of water – or other liquids – for maximum hydration, it features a wide mouth for ice cubes and a folding carry loop. It was designed for durability with triple insulated stainless steel to keep cold drinks cold for 25 hours. Corkcicle's quick-sip cap makes it easy to sip as you exercise.
