Jinwrote a review of Deuter Airlite 22L Backpack on June 16, 2016
Familiarity: I've used it several times
Love having a smaller pack that I can use for shorter hikes and excursions. It is large enough to fit up to a full 3L water reservoir of any brand and still has plenty of space for other stuff in the pack. the pockets on the waist straps are great for holding small items. There is a system that keeps the bulk of the backpack away from your back so there is airflow on your entire back. That's a nice touch. Would definitely recommend this or anything in this series to anyone.
