The Hannah ENDEAVOR 20 is a single-compartment trekking backpack, designed for day trips. It has an anatomically shaped Air vent back system for air circulation, comfortable padded shoulder straps, a detachable lumbar strap and a chest strap with a whistle. Thanks to the compression straps, you can tighten the backpack and it will be more stable and can be carried more easily. All-day hydration is key so you will definitely appreciate the special pocket with a hydrovac outlet. The backpack also has two handles for ice axes or trekking poles.
