Lightweight, versatile climbing backpack for alpine activities The versatile TRAD 33 S are robust, lightweight climbing backpacks for alpine tours that require clever functions and light weight. The lid compartment has a key holder and space for small items, while the main compartment can be easily accessed via the large opening at the top or the circumferential zipper. On the outside, 420D Ripstop Material with 88% recycled polyamide protects against scuffing in craggy rock terrain. Material loops and ice axe and rope fastenings mean equipment can be securely carried without being unnecessarily bulky. The comfortable back system optimally distributes the load across the back and makes the backpack a pleasure to carry, and the aluminum frame can even be removed for climbing. And the length of the back is designed to keep the neck free during climbing, when you have to keep looking up. Hydration system compatibility, an emergency card and a chest strap with a signal whistle round off these versatile climbing backpacks. BACK SYSTEM: HIGH FLEX CONTACT The back system for this climbing backpack offers a light-weight, removable aluminum frame and a full-contact carrying system. The frame is very flexible, but rigid along the horizontal axis in order to bear as much weight as possible. Thanks to its 3d shape, the backpack fits closely to the back and guaranties great freedom of movement and the best possible wear comfort. ORTOVOX - Trad S 33l Backpack arctic grey
