As you train for that epic summer summit, look to the Ratatosk 3. 0 30L Backpack from Klattermusen to tote your gear across low- and high-elevation trails. Stacked with usable features like elastic gear straps and attachment points for trekking poles and an ice axe carry, the Ratatosk helps keep all your external gear organized while the roll-top feature adjusts easily to the amount of gear you're carrying inside the pack. As for comfort features, the padded backplate and removable hipbelt help make small adjustments to give you maximum comfort on the trail so you can focus on where you're placing your feet instead of the hot spots building on your shoulders.
