Uphill hiking is about to get a lot more comfortable when you hoist the Deuter ACT Trail 20 SL Daypack. The Aircontact Trail (ACT) system at the back gives you padding where you need it while a middle channel pumps fresh air through to help dry out perspiration. The Slimline Women's Fit System (SL) is perfect for ladies or dudes with shorter backs with its comfy, contoured shoulder straps that are narrower and shorter, and a padded hipbelt that can change angle to fit male and female hip profiles.So you know this Deuter backpack will be comfy, now on to the features. You have full access to your gear through the 2-way zipper on the front and lots of extra stashing-and-lashing options with a top lid, a front stretch pocket, side mesh pocket, zippered side pocket and trekking pole and ice axe loops too. The hydration sleeve accommodates a 3 liter reservoir (sold separately) and a hidden rain cover deploys from the bottom pocket if an unexpected squall rolls in. Premium German engineering and craftsmanship make this 20 liter pack the perfect carry-all for an easy dayhike with the family or a quick solo ascent of that peak you've been eyeing from your campsite.
