Fuel up and keep going with your CamelBak Octane 12 Liter! It just keeps getting better with improved reservoir flow rates and updated mesh ventilation that helps your body breathe easier while staying snug during bouncy movements. Cargo compression adds to the overall genius of this design, keeping the pack close to you for better balance. When you're going through rough terrain or increasing in elevation, attachments for trekking poles can come in handy.
