Whether you're venturing by splitboard or snowmobile, get everything you need for the day to your secret zone with this burly bag. Vertical snowboard straps hold your board when you're bootpacking the last stretch to the peak, and they also serve as a compression system to keep your pack as low-profile as possible. It also has a horizontal board carry option for riders traveling by sled. An easy-access shovel and probe pocket lets you get to your avalanche rescue gear as quickly as possible in case of a slide. The external pole storage holds your trekking poles when you're shredding down, and a padded waist belt keeps the pack from flopping around and throwing you off balance. It's also hydration-compatible so you can keep precious fluids handy, and a fleece-lined pocket keeps your goggles from getting scratched when you're hiking up in sunglasses.
