The Tjalve 2.0 Backpack is made from light, recycled polyamide Retina® fabric. The carrying system in combination with the 4-S sternum strap ensures the bag fits close to your body’s center of gravity, and the adjustable shoulder straps and back panel come in 3D-mesh for better ventilation. There’s a lid covered cinch opening on top for easy access, removable waist strap for a snugger fit, two smaller mesh side pockets for stowing accessories, and an elastic cord system for quick attachment of insulation or a shell jacket. The pack is also designed to easily fit a hydration system.
