Why We Like The Black Diamond Crag 40L Backpack

Whether we're headed to the boulder field, our hometown crag, or the gym, we're loading our gear in the Black Diamond Crag 40L Backpack. The abrasion-resistant material can handle grating desert terrain and sharp wooded areas, as well as keep our nut tool from poking through on crack days. The front pocket secures our keys for the day and keeps our guidebook readily accessible, while the internal organizer makes our tape and balm easy to find.

Nice and light bag

Needed a bag to just pack some light stuff in for day trips, helps all of my climbing gear and had extra room too

Carries the Load and is Comfortable

This pack has the easy access just like you’d hope for a crag bag and gets the job done flawlessly

Workhorse

This thing fits everything for a day of climbing inside. Rack, rope, draws, shoes, helmet. Material feels very durable. I wouldn't hesitate to haul this thing a few pitches, but I mainly use it for single pitch "crag" days.

best gear hauler!

Familiarity:
I've put it through the wringer

The capacity of this bag is awesome. I can fit a rope, harnesses, a few pairs of shoes, and my rack all easily. The front pocket is perfect for throwing in phone/wallet/keys. I love the opening style of the duffle bag and the full side zip, along with large top opening. Even when it's full of gear, the hip belt makes it easy to haul on hikes into the crag.

Very spacious

Easily fit a 70m rope, harness, helmet, shoes, full set of nuts, double rack of Cams(doubles of 0. 3 to 3, 5 offsets, and a number 4), 8 alpine draws, half a dozen extra slings, cordelettes, belay and rappel devices, and extra carabiners. Even with all that, still very comfortable to wear.

Perfect Crag Pack

Just what I was looking for from a climbing pack! Strong straps and back support, with plenty of space for different gear.

Great pack, improved design

I already loved the old version of this pack. It is super simple, lightweight but sturdy enough to get thrown around over sandstone every day. It's comfy enough for a long approach, but nothing extra here. This newer version/colorway seems to have a bit sturdier fabrics without sacrificing weight. Great pack.

Hope they bring this back!

Maybe one of my all-time favourites for gear! This is my go to, especially for alpine climbing. What? Yeah, it's burly enough for an occasional haul. It's simple. It carries all the gear on the approach. And sure, I don't need 40L for the climb, but I really like not overstuffing my pack on an alpine climb. The side zipper makes it super easy to access any of my gear, without worrying I'm gonna drop something trying to access what's underneath. PLEASE BD...keep this puppy going!

Perfect

Perfect climbing pack! Can fit plenty of gear from a monster rack at the creeek, to a sport climbing rack and all the snacks for the more chill sport climbing days. Doesn’t do great hauling offwidth gear but that’s obvious. So run out the off width section and take triple of everything else!!
