The medium sized mama bear to Evoc's gear crushing CC 16L papa and minimalist CC 6L baby bear, the CC 10L Bike Hydration Pack is perfect for day long rides where you want to bring food, water, and a layer along for the trip without dealing with any extra bulk. The main compartment zips open to reveal a reservoir sleeve capable of holding bladders up to three liters and enough room to stash a layer and some snacks. A top pocket keeps your sunglasses safe, while another compartment holds your tools and a stowaway helmet carrier keeps your lid secure when you're in transit. Evoc made sure the CC 10L was tough enough to stand up to trees, rocks, and the occasional tumble by constructing the body from rugged 210D nylon ripstop and the bottom from 600D polyester. It increased water resistance by treating both surfaces with polyurethane, and built the straps from a combination of 3D AirMesh and cushy Atilon foam. The back panel uses Evoc's Air Pad system to keep air flowing between your back and the bag, and the lightweight hip and sternum straps keep the CC 10L from bouncing around when you're getting gnarly.
