When seconds count, you don't want to waste any digging around in your pack to find your shovel, shovel handle, or probe. Mammut's Spindrift Guide 45L Backpack has a separate pocket with sleeves for both the probe and shovel shaft so you can quickly assemble your gear and move on to finding your partner. The 45-liter size means you can bring extra layers and food for all-day yo-yo laps or a multi-day hut trip, and this pack has loops for your ice tool and gear loops on the removable waistband. A three-step back length adjustment system helps you get the right length for the shoulder straps, and ski and snowboard carry options secure your planks.
