Why We Like The Black Diamond Stone 45L Backpack

Black Diamond's Stone 45L Backpack gets our climbing gear to and from crags with a super comfortable carry using padded straps to keep our shoulders prime for the climb and a removable padded waist belt if the crag is only a stone's throw away. A drawcord skirt opens the top access wide, so we can stuff gear in without a hassle, and Black Diamond added a full-length side zipper for easy gear retrieval. The Stone also has a removable floating top lid when we want to pack in a little less weight. We strap our climbing rope to the outside of the pack with the tuck-away strap, leaving more room inside for a full trad rack, harness, shoes, food, and layers.

Great, sturdy backpack!

Use it for everything everyday since 2 years! Travel, crack, multipitch, ... Great: Sturdy, good to expand/compress, removable hip belt, love that you can clip chest belt with one hand! Not perfect: not waterproof, inner material peels off

2 way zipper makes the difference.

Bag has a 2 way side zip that can be opened from the top for easy loading or from the bottom for quick access. Makes for a solid crag bag or comfortable to carry for a distance which is what I was hunting for. Lighter weight than the mission bag. Gear loop on the waist belt would be nice. Seems just big enough to fit rack rope shoes harness and helmet along with some other things inside the pack, even more space with the rope on the outside.

Great Day pack

This Pack feels great under heavier loads. Has enough space to carry all the equipment you need to the crag. Or even use it as a hiking/backpacking pack. Only thing to make it better is to add buckets to the pack lid with long shoulder straps added to turn the pack lid into a send bag for the actual climb. 5 out 5

Really good beginner pack

Good pack to start cragging with as a beginner but still have features for bigger climbing trips later on. Enough space to carry everything with the rope on top. Love having the top pockets for keys and snacks. Very comfortable to wear and hike with thanks to good back support and strap adjustments.

New crag pack

Got a small pack and am happy to say it fits perfectly around my waist and torso. Well cushioned so will work well once I get all my gear/rope in the bag. More pockets than I expected and lots of room in the brain of the bag. Deducted a star because it doesn’t have a clear pocket for the water bladder so I’m worried about my climbing year puncturing the bag.

Great Bag

The construction of the bag is top notch and it holds a lot. Fits my 60 meter rope in Burrito bag, harness, shoes, gloves, belaying gear, chalk bag, clothes, food, scratch mat, tarp, and misc. things like phone and keys. It has a space for a water bladder too. Solid bag for the gym or the crag.

Quality Backpack

I recently purchased the Stone 45 because I realized that I needed a backpack solely for going outdoor climbing. My regular backpack just wasn’t cutting it. After a day of trekking with the old pack and a sling bag for rope, my upper back was extremely tight and tense the next day or two. However, the Stone 45 comes with a brace so that you aren’t leaning forward to carry everything. The material is strong and I like the ability to open the pack via zipper in addition the stuff sack style.

Seems great so far

I love bd packs. They are often simple and just what you need. I had the old epic 35 and the zipper finally broke this summer. Was sad to see they don’t carry that pack anymore. I thought the stone 45 seemed comparable. I have it and haven’t used it but these are initial impressions: it fits well and the design is sleek. Seems a bit heavy the material is pretty thick, I was disappointed about this but it should hold up well. I also wish I’d had the comfort, shifting shoulder straps, though it does seem pretty comfy. I will likely use it for all kinds of things but not climbing: I Love my crag 40 for that. Hoping to use this for short backpack trips. Seems like a great pack.

Bombproof Crag Pack!

Great pack. Absolutely bombproof. The fit based on the sizing chart was spot on. Plenty of pockets/straps/clipping points. The perfect size for toting a rope, trad rack, harness, shoes, helmet, etc. to the crag. More quality gear from Black Diamond.
