Minimalist in looks but not in features, the Prolighter 25 has a cavernous main compartment that will easily hold everything you need for a day in the alpine. A hydration compatible design allows you to equip the pack with your go-to hydration system, so you stay properly hydrated during the approach. The front of the pack will easily carry two ice axes, and it has a rope holder compression strap to carry a length of climbing rope. A breathable back panel ensures a comfortable fit, while the continuous shoulder straps and hip belt keep the pack comfortable once loaded down with gear.
