A worthy partner for the dark.

Load up your water, snacks, layers, and headlamp in the Black Diamond Magnum Backpack, and get ready for your next caving excursion. The Magnum’s rugged 210D silnylon comes in handy when you’re plunging into the abyss and scraping up against all kinds of who-knows-what. Mesh side pockets and a rear-mounted elastic cord allow for last-minute gear additions when you’re running out the door to catch your ride. The Magnum weighs in at a scant 15 ounces, so it won’t bog you down when you’re getting down.

Great Pack Except for Waist Strap

  • Familiarity: I've used it several times

I've liked the pack except for one significant problem. The afternoon before a 10 day Himalayan trek, one of the waist straps (there are two that meet/buckle in the middle) came loose and fell off. They should be attached more securely. My guide had it replaced with one long strap that was somewhat unwieldy, as I always had to reach way back to buckle/unbuckle it.

Bet it's better for hiking than biking

  • Familiarity: I've used it once or twice and have initial impressions

Wanting a replacement for my old Black Diamond Bbee, I decided to go with a Magnum, not realizing it eschews the yoke-style shoulder straps and webbing handle of the Bbee for a more traditional strap to bag connection. The handle on the Magnum is smaller and made from the same fabric as the bag, attaching in the same seam as the straps. I found this becomes rather uncomfortable when riding a bike. Thus, I imagine the Magnum works much better for hiking than biking or skating.

Perfect size

  • Familiarity: I've put it through the wringer

This bag is the perfect size to fit all your sport climbing gear. This bag fits the following with ease. 70m 9.4 mm bluewater dominator rope, 2 petzl harnesses, petzl grigri 2 belay device, 2 pairs of shoes, 32 oz nalgene, a couple of granola bars, and 3 beers. Sounds like a perfect pack for a great adventure right? Thats because it is. You will have room for all your climbing needs.

Black Diamond magnum day pack

  • Familiarity: I've put it through the wringer

Good little pack. Nice and simple. Large enuf main pocket. It does have a hydration pouch and opening for the nozel so the description to the left is incorrect.

Good pack

I like this pack: Light, comfortable, and fits everything I need for a 10-mile (or more) day in the woods. I have mostly been using it for day hikes and longer trail runs. The cinch straps work great for compressing the pack.

Good pack

Very small bag

  • Familiarity: I returned this product before using it

I needed a bag to keep my climbing harness and accessories in. This bag was far too small for the task so I returned it. Great service on the return, though, thank you!

Just the right size

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I used this pack on a free solo of an ice climb in Pinnacle Gully, Mt Washington. In it I had: A 30 m 8mm rope, 30 m of 4 mm (pull line), MH phantom Jacket, extra pair of gloves, 500 ML water bottle, Headlamp, 2 ice screws, belay device, v-thread tool, several cords for v-threads and a few biners and slings. I had my crampons and ice tools strapped on for the approach. Forget about the elastic cord. The only thing is might hold is a layer that you shed (fleece, etc). While climbing, I didn't even know I had the pack on. The only complaint is the waist belt. One, the buckles didn't hold and both sides fell off in the trunk of my car. I had to tie small knots at the ends so it didn't happen while wearing it. I have a 34" waist and the belt just fit over my light winter layer (heavy base layer and single layer goretex). The waist belt should be longer and the ends sewn so it doesn't fall off.
BTW, It IS hydration compatible even though it says "no" to the left. It has an inside sleeve and an opening for the tube.

Can you strap a climbing rope to it?

Great Pack!

I've had it for a few months using it for taking my climbing shoes to the gym and going on day hikes. Its nicely put together with a very strong material. The straps and back are made it a different material that makes the pack very vented so you don't have a sweaty back.

I'd buy it again its a great pack. It looks good, works well, durable, what else do yea want?

Here's an overview, but more thoughts and many picks on my blog:

Overall, it looks like a very well thought out pack. I haven't tried it yet, but I'm sure it will smush up into my suitcase with no trouble; actually I'll probably just lay it flat. The back panel has a nice airy foam pad to help air move between you and the pack, but it you're hoofing it in the heat, I doubt it will stop you from soaking. The side stretch pockets are a bit too small to securely carry water bottles. The old style was better (this is why four stars).

Nit pick: the front web compression strap differs from the old style (and many other bags) by using really thin, narrow webbing vice shock cord; this looks cool out of the packaging, but cinching it up a time or two tends to twist the webbing and the appearance is not as nice. A decent shot at aesthetic innovation that won't stand the test, I'm betting. On the other hand, the webbing will continue to function well I think, and you don't have to replace shock cord that has lost its stretchiness.

Overall, I'm pretty happy. The new Magnum shows a lot of promise. I'd say it's probably a bit larger bag than I need, but I seem to end up carrying things for LB and daughters on vacation so maybe that's good.
