Mammut&';s Lithium 20L Daypack helps us get out on the trail as much as possible. Sure sometimes we won&';t be able to hike, but wet weather will never be the reason. Mammut made this daypack with a rain cover to shield all our hiking gear from wet weather. We also like Mammut&';s original detailing with the phone pocket that folds out of the hip belt for quick-and-easy access to our phones when we see an animal trotting by. Details:- Daypack designed for rain-or-shine hiking 20L capacity appropriately sized for full days on the trail Air channels in 3D foam offer extra ventilation Detachable rain cover treated with PFC-free DWR Carry system for trekking poles Fold-out phone pocket on hip belt Compression straps secure the load no matter how much is packed
