For fast-moving alpine missions.

Load up the Black Diamond Blitz 20 Backpack before conquering demanding alpine routes where fast-moving efficiency is essential. The Blitz 20 features Dynex material for weight savings and rugged durability required for alpine and climbing use. The pack's 20-liter capacity reduces excess bulk, but without cramping your ability to carry all your climbing and alpine gear on demanding routes. Its strippable design includes a removable waist belt and bivy pad when saving every ounce is crucial to success.

The one-handed closure facilitates quick, easy loading on time-sensitive routes and grueling approaches. Hydration-compatibility promotes convenient drinking when you're pushing yourself at high altitudes. Moreover, there's a waterproof top lid pocket for safely storing your sensitive electronics, GPS devices, and maps when it's raining and snowing heavily. Pick Pockets carry your ice tools externally, making this pack a great addition for tackling mixed routes and ice climbing alike.

Stellar little pack!

  • Familiarity: I've put it through the wringer

This pack is the perfect size for a summit pack or for single day / super light alpine adventures. The lid closure is simple and reliable, the internal 'ninja pocket' is incredibly handy, the lid pocket is waterproof (as advertised), and the ice tool attachment is the best I've ever used (simple, secure, and I can get an axe out without taking the pack off). I've used this pack for rock climbing, alpine climbing, hiking, travel, and ski touring and it has been perfect for all but ski touring (ski carry is possible with addition of a strap through the ice axe sleeve , but it's a little fussy). I've even managed to pack enough to do some 2 day climbs (bivy, no tent). I generally don't use the waist belt (which is easily removable) and I've found the shoulder straps to be well shaped and quite comfortable even when the bag is packed to the brim. The exterior fabric has been quite durable, but it does show dirt.

What isn't good about this bag? The body of the pack is absolutely not waterproof and after a little bit of use it is hardly even water resistant. If I could change one thing about the bag it would be to switch to a durably waterproof fabric. Second, the back pad while technically removable (for use as a sit pad / emergency bivy), it is not practical to use it this way. I would prefer if it was easier to remove (like Cilo Gear packs, for example). That's it really.
