Range extender: The Brenta 36+6 liter hiking backpack, weighing just under 1,500 grams, is light enough for ambitious day trips, yet offers enough volume for multi-day hut hikes. Compared to the smaller Brenta models, the Ergoshape shoulder straps are slightly more padded. In addition, the hip belt features a zip pocket on both sides, and there are two attachment points for trekking poles or ice tools. The storage space can be expanded by six liters via the height-adjustable lid. But here's where it gets clever: the buckle of the lid compression is detachable, ready to serve as a backup for any misplaced or broken snap buckle. Venturing deeper into its features, the Brenta 36+6 impresses with its Aeroflex 3D mesh back, ensuring excellent ventilation and a sturdy frame that delivers a secure fit in any terrain. Convenience is key with its front access for quick gear retrieval and side mesh pockets accessible without having to remove the backpack. Completing its arsenal of amenities are the stretch pocket on the front, valuables compartment in the lid, integrated rain cover, and a chest strap with hydration tube attachment. Plus, the Brenta 36+6 is armed with Eco Finish, providing PFC-free water and dirt repellency for added durability.
