What Our Gearhead® Experts Are Saying: “I’ve used this pack for quick pre-work ski laps where stopping is not an option. The vest-style fit keeps it glued to my torso, and the ski lasso lets me stash skis without taking the pack off, which honestly saves time and energy when things are cold and fast.”Early mornings move fast when there’s snow on the skin track and limited time to get laps in before the day starts. We built our routine around efficient systems, and the Firn 18L Backpack from Osprey quickly became part of that flow. Whether we’re skinning straight from the car or transitioning on a windswept ridge, this pack stays tight to the body and never feels like it’s slowing us down. The Firn 18L Backpack is designed for movement-first ski days where access matters as much as stability. The vest-style harness spreads weight evenly for comfort during long climbs, while on-body pockets keep skins, tools, and essentials within reach. A front avalanche tool pocket stays organized and fast to deploy, and the innovative ski lasso system allows quick ski carry without breaking stride. Every detail is focused on keeping transitions smooth and momentum intact when the window for skiing is short.
