Getting enough to drink is essential during outdoor activities for several reasons. In addition to pure refreshment, proper hydration helps keep you alert, which is important when you are out on the trail. Proper hydration also facilitates circulation and helps your body release toxins and absorb nutrients.

A Camelbak hydration pack is among the most recognized types of reusable water bottle for hiking and camping. The Camelbak Hydrobak 50-ounce reusable water bottle is an excellent choice for shorter treks--it carries enough water for 1 to 2 hours of hiking. This Camelbak water bottle features a low-profile design for maximum stability, as well as a breathable mesh harness and zipper pocket for keys and other small items. In addition, the Camelbak Hydrobak 50-ounce water bottle can be easily refilled using the pack's trademarked Omega HydroTanium reservoir. The Camelbak Hydrobak also comes in a 70-ounce size and both sizes feature reflective elements on the pack and on the harness.
