Its hard to find a big pack designed for splitters and skiers. I have made more than 6 different packs and here, I am submitting my most recent creation. I call it the Ultralight Chief. It is a 3888 cu in (63 liters) backpack, not counting the top pack. It is designed to carry more than the gear you need for multi-day winter excursions, because we all have to carry our favorite adult beverage along with all camping and ski/split gear, right? That's a lot of stuff! The Ultralight Chief weights under 3lbs with HPDE frame sheet and aluminum stay.
