Osprey Bottles and Flasks

Choose reservoir size based on your pack's hydration sleeve capacity and trip duration. Common sizes are 2L, 2.5L, and 3L. Also check if you need an LT or LS type for your pack's clip system.

Use warm water and mild soap or a cleaning tablet. Rinse thoroughly and dry with the reservoir open. Never use a dishwasher or boiling water.

Wrap the tube in an insulator or blow water back into the reservoir after drinking. Keep the reservoir close to your body to maintain warmth.
