For quick drops into the backcountry on trail runs or hikes, Deuter created the Attack 18 SL Backpack. The Attack is outfitted with all the necessary technology to keep you enjoying the open air outside, rather than worrying that you forgot something or don't have enough water. This pack is hydration compatible so you can have your reservoir just a sip away. The helmet carrying option is helpful when you don't know what could be falling from above. You also are always prepared with this pack's raincover that conveniently packs into the pack. The Deuter Shield System is also up for the task of keeping you safe. With injury-prevention technology, the Shield alleviates weight and resists impact if you were to fall, so that you can just get right back up and keep on booking it.
