A fine-tuned rolling pet for climbers who like to move fast in the mountains, regardless of the terrain. It is light, practical, waterproof and just right for your jacket and warm sweatshirt. The shoulder straps are not only comfortable, but also perfectly designed, as they save space in the backpack thanks to their pockets. Poles and drinking bottles have their own pockets there and are handy when their time comes. You don't even have to slow down. The durable material, taped and welded seams and the roll-up system of the lid prevent rain and splashing water, so you have everything dry even if you get caught in the rain. Ergonomic vest-style shoulder straps will keep you comfortable even when jumping over rocks.
