Summit Pro

For the trips that do not end at the car. Everything Summit does, with a second battery and a swap that takes seconds.

Hut to hut, multi-day traverses, backcountry work where there is nowhere to plug in. 56 km of assisted climbing across two packs.

• 1000 W combined output · 32 Nm per hip
• 28 km × 2 — two batteries, hot swap
• 2,550 g worn weight, plus 480 g per spare battery
• IPX5 · operating range -10 to 45 °C

Worth it if you are out for more than a day. If you are not, buy Summit and put the difference toward boots.
