If you like carrying your hydration on your back, but not much else, the women's-specific Sylva 5 is your pack. An included 2.5-liter reservoir keeps you from going thirsty and a separate main compartment lets you bring along the essentials. Perfect for pedaling in hot and humid climates, a trampoline-style AirSpeed backpanel creates a comfortable fit and a breeze at your back. The BioStretch harness offers superior stability with wing-shaped shoulder straps that mimic the natural arc you assume when you're in a riding position. An integrated removable raincover keeps your stuff dry and attachment points exist for your helmet and tail light.
