Deuter Ascender 13L Hydration Pack Indigo, One Size

The Deuter Ascender 13L Hydration Pack keeps us comfortable, and, more importantly, hydrated, as we run or hike our favorite alpine trail. Two shoulder strap pockets store the two included soft flasks for easy access, while the interior is compatible with a 3L drinking system or bag. The wide, ergonomic vest-style shoulder straps feature an elasticated compression system for all-day running comfort.
