For those thirst-inducing summer rides, we roll out with the Osprey Kitsuma 7L Backpack. The lightweight build features ridged foam and a center air channel to keep us feeling the breeze, while the contoured shoulder straps and adjustable sternum and hip webbing deliver a stable carry as we pedal through the trees. Thanks to the included 2. 5-liter reservoir, we stay hydrated on the move, keeping both hands on the bar more often than not.
