The Guide 34+8L Backpack is designed for mountaineering and climbing. It features a high-denier nylon blend that balances strength and weight. The lid extends to provide an extra 8 liters of capacity. Removable hip fins reduce weight, and a zippered hip belt pocket offers quick access to small essentials. External bungees secure ice axes and trekking poles, side straps allow vertical ski carry, and a helmet mount attaches to the exterior.
