Gear Review: Black Diamond Rock Blitz 15L Backpack (and Carabiner Contest)

Black Diamond Rock Blitz 15L Backpack Review


This summer I received the Black Diamond Rock Blitz 15 backpack to review and I’ve since logged about 25 days of multi-pitch rock climbing and guiding and a half dozen hikes with it. Weighing less than a pound but able to carry my full summer guiding kit I found this to be a great multi-pitch climbing pack and only have a couple small tweaks I’d love to see Black Diamond make.

Contest: I’m giving away two Black Diamond Mini Pearabiner Screwgate Carabiners! Read the photo captions below for how to enter!

UPDATE: Contest over! Congrats to Chris B. and Forrest for identifying the climbs!


Let’s start with the manufacturer description:

A worthy addition to any multi-pitch kit, the Rock Blitz 15 is designed to move with you pitch after pitch, carrying all the essentials to the summit. Featuring our signature Blitz-style main opening and a side zip pocket for quick on-route access to a phone, topo, or camera, this pack also has a stripped-down profile for moving fast on big lines. The top closure strap doubles as a rope carry once you summit, and external H2O hose routing gives you the option of staying hydrated on the send. The pack’s EVA padded shoulder straps and back panel make for all-day comfort, while the sternum strap and waist belt are fully removable to save weight on fast and light pushes.

  • External side zip pocket for quick access to guide book / phone / camera
  • Stripped down pack silhouette for moving fast on multi-pitch missions

  • Fully removable sternum strap and waist belt to shave weight when necessary

Sizing/Fit/Comfort

The Black Diamond Rock Blitz 15 only comes in one size. Like most climbing packs designed to be worn while leading multiple-pitch rock it rides high on my 5’9″ build, 16 inch torso. The thin waist belt easily rides above my harness and helps secure the pack from swinging around when moving over terrain. The contoured EVA foam shoulder straps easily distribute the weight of a full kit. My only wish is the sternum strap used a more traditional slide adjust system vs the girth-hitched attachment points it currently uses and that the sternum strap buckle had the built in whistle that most climbing packs use these days.

Performance/Volume/Durability

For a simple pack there is some definite stand out features that made me really enjoy this pack. First off is the 15 liter volume. With careful packing I could fit a full guiding kit in here. For reference this is what I fit inside the pack:

This much gear was a snug fit and I’d either carry or just wear my Black Diamond Vapor helmet to the wall. The 840 denier ballistic nylon held up great to a full season of guiding. While I never hauled the bag up a pitch I did wear it through multiple squeeze chimney’s and the pack still looks quite new. The external side zip pocket is advertised to carry your phone, guidebook, or topo. I actually fit my first aid kit and my phone in it for easy access!

Video

Here’s a quick look at the pack after finishing a day of climbing at Cathedral Ledge.

Black Diamond also produced a sweet little video showcasing this pack and a couple other products. I especially liked how they used the “guidebook/phone” pocket… skip to 1:58 to see the 11th “essential”…

Summary

This is a great little rugged multi-pitch backpack! Not a lot of thrills but simple and effective for what it was designed for! While it’s main end-use is multi-pitch trad climbing I found it great for quick trail hikes around the White Mountains and along the Maine seacoast. It was also quite useful on a family vacation when were walking around multiple seacoast towns. If you’re in the market for such a pack take a good look at this one!
