With an ergonomic, women specific fit and ventilating features, the Deuter Women's AC Aera 22 SL Backpack will make chasing waterfalls and hiking to hidden alpine lakes all the more enjoyable. The narrower shoulder straps with soft lined edges are set closer together to fit smaller shoulders, and prevent chafing or uncomfortable bulk at the chest and armpit area. The hip belt is positioned and shaped for optimal comfort and support around a woman's or smaller sized figure. The backpack fits torso lengths ranging from 14. 5 to 18 inches, and offers plenty of capacity to hold supplies for a long day hike. After you set out on the trail, the supportive spring steel frame and side compression straps support and balance your load, while the ventilating AirComfort mesh back panel provides breathable comfort. If you're out in drizzly weather, the backpack's water resistant fabric will protect contents inside, and an integrated rain cover offers added protection if the drizzling doesn't let up or turns into a downpour. The backpack is compatible with your hydration reservoir, and includes a reflective attachment for your drinking tube so you can easily find it if you're out on the trail before sunrise or after sundown. Stick items you'd like quick access to in the mesh side pockets and store valuables in the protected zippered lid pocket. Attach tools or carabiners to loops on the lid, and slide your hiking poles through the side pole attachment loop. Once you get to your first waterfall of the day and want to grab your camera from the inside of the backpack, the front panel opens up for easy access.
