Magnum 20L Backpack

When a long out-and-back is on tomorrow's agenda, the night before is a time of preparation. Most importantly, you need to make sure your alarm clock, outfit, and the Black Diamond Magnum 20L Backpack are ready for an early start, so you aren't fussing with your gear when you should be driving to the trailhead. This pack has a low-profile design so it doesn't slow you down, with enough space for all of the essentials you'll need on the trail. It has plenty of room for your food, layers, and first aid kit—and even your DSLR if you're feeling brave. It keeps your water close in the hydration-compatible sleeve, so you have no excuse for not staying hydrated, and organizes small items in accessory pockets so you can find everything in a pinch.
