Serious mountain bikers, this DEUTER Attack 18 SL backpack is basically your new safety gear! It's got a TÜV/GS certified removable back protector made from special foam that absorbs multiple impacts - meaning it protects you during those rough falls but bounces back for the next hit. The 18L capacity gives you plenty of space for essentials, and it sits incredibly secure thanks to the high hip fin attachment (no bouncing around on crazy descents!). There's a dedicated compartment for your hydration system (deuter Streamer 3.0 compatible, but not included), plus a fleece-lined glasses compartment to keep your shades safe. Outside, you've got mounts for your full-face helmet, a stowable helmet holder, and compression straps to secure protectors. Designed specifically for women with that perfect fit that moves with you on the bike. Whether you're hitting demanding trails or just want that extra safety on technical rides, this backpack has your back - literally! Quality German engineering that serious riders trust.
