This backpack is perfect for all your multi-day expedition-type treks. Featuring a water-repellent outer, your belongings are guaranteed to be protected against the rain while traveling. The top-loading main compartment is spacious, and it is secured with a lid and three quick-release buckles. The pack balances lightweight design, reliable comfort, and ventilation. The aluminum alloy bars located in the back are designed to reduce pressure and allow the back to breathe. The padded and buckled waistband fitted with two zipper pockets adjusts to your hips for load stability, and dual shoulder straps with ergonomic padding provide comfort. There's a slew of attachment loops around the pack for accessories such as an ice tool or a trekking pole.
