Great crag bag

  • Familiarity:I've put it through the wringer

I've had this bag about a year and have probably had it out 50+ times now. I've used it for both sport and trad climbing trips, on approaches ranging from easy 15 minute walks to 1.5 hour hikes. In terms of capacity, it easily holds everything you need for sport climbing including a 70m rope (inside). For trad climbing with a full rack, carrying a rope inside would be a squeeze but it is possible. The rope can be carried outside the pack but I've never tried it. I prefer to carry my rope in a separate bag on my chest and my rack in the Neon Gear 45. In terms of quality, all of the zippers are still working smoothly, the plastic buckles are in tact and there are no tears in the material. The included rope tarp is a little small but totally usable. My only real complaint is about the waist belt. On some of the longer approaches it starts to cut into my sides and becomes a bit uncomfortable. I'd like to see some padding like you see on some of the Osprey packs. Other than that, I love this thing and will most likely be buying another one when it finally wears out.

Top Notch

  • Familiarity:I've used it several times

I have been in need of a larger climbing pack for some time now and after quite a bit of research, it had to be this bag! I can fit all the gear I need for a whole day on the rock (Rope, chalk, harness',shoes, biners as well as a windbreaker some rain gear and food) with room to spare. The internal pockets are excellent for keeping your gear organised so you can grab gear in a hurry.

the Ultimate Rock Cragging pack

  • Familiarity:I've put it through the wringer

I've been using this pack for a few years now, it's not flimsy. Plenty of room to carry multiple ropes, rack, harness, shoes, food, water, helmet, puffy. Lots of pockets and internal gear loops to organize gear. Top load pack w back zip to create duffel/rope bucket options.

Highly rec if you need a crag pack.

Great pack, seems a little flimsy

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

The 30 liter version of this pack is my goto pack for my local crags or going to the gym to climb. I have to admit... I've beaten the thing to death, and have yet to have any durability issues with it.

At a casual glance it seems a little flimsy. The main zipper is a standard, low gauge zipper that always seems ready to blow. The circular zipper on the back of the pack is nice... however, its also a small gauge, flimsy zipper that appears a little too weak for its job. The top compression strap holds a rope well, but with adequate compression it pulls very hard on the stitching, which doesn't appear reinforced. I've stopped carrying a rope on the pack. If I need to carry a rope I'll bring my Black Diamond Speed 40, or just carry a rope bag.

Inner rack loops are nice, and the outer daisy chains hold gear and shoes well. The back access is convenient, but a little frivolous. I suspect the zippers will be the first to go since the rest of the pack is bomber. The inner pocket and chalk bag are nice as well, and the included rope bag is definitely worth using, and adds value to the pack.

All in all its a great pack and carries very well. The 30 liter is also a good choice if you're sticking to local crags or the gym.

Great bag

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

Bought this a couple months ago as a gift for my man and he loves it. I did A LOT of research into different bags for climbing and this seemed to come out on top. We work where we can't get to climbing spots very often and have only used it twice but it's been great. He found it comfortable and it fit our gear nicely. We've only gone for a couple short day climbs (fairly short approach at Grassi Lakes, Canmore, AB) but it's doen the trick!

Minimalist meets functionalist

    The opposite of David I love packs that have 100 different pockets for me to catalogue and organise my gear (climbing as well as miscellaneous). The Black Diamond Demon Duffel had caught my eye previously, but the fact that it only had one full length internal pocket kind of put me off. The Mammut Neon Gear 45 is the perfect blend for me of minimalist sleek design, while retaining the best features of a technical pack. The two pockets in the lid, and the "Chalk Bag Pouch" allow those with a mild case of OCD to organise their gear for easy access, while the enormous main compartment will easily swallow a rope, three pairs of shoes, chalk bag, harness, 12 draws, food, water and a shell for those nippy winter days. The internal gear loop is handy for organising belay devices and the like, although it is definitely not designed to carry more than about 10 draws (I keep mine in a separate pouch and store them in the main compartment instead). This is the perfect crag pack for sport climbing, but if you are into your trad you will probably want to look elsewhere. I haven't tested it out on any excessively long approaches yet, but so far the U Frame and padded back panel have been extremely comfortable. My only negative (hence the 4 stars) is that the zippers on the back panel stick occasionally which can be very frustrating. Hopefully they will wear in with longer use, but this is a very minor drawback to an otherwise flawless pack. If you are into your sport climbing and bouldering and looking for the perfect crag pack, you need look no further.

    Ultimate Sport-Climbing Backpack

    • Familiarity:I've put it through the wringer

    I am allergic to backpacks with too many "useful straps and pockets" because I find that, most of the time, they just get in the way, and add unnecessary weight and more components that potentially will break. With that said, this backpack has all I want and need in a day-use sport climbing back pack. I can comfortably pack a rope (in the integrated rope bag), Chalkbag (also packed in the integrated pouch that neatly clips to the inside of the bag and keeps the rest of your stuff free from chalk), 15 quickdraws and belay device attached to the gear loop in the back, a pair of climbing shoes, harness, water bottle, jacket and other small accessories I find useful. To create more space in the pack, I just take out the rope, and attach it to the strap on the top lid or in a separate rope-bag. Now, if I would go trad climbing or do anything similar that requires more gear, clothes, food, accessories etc..., I would go with a different bag. But for me, for everyday use, back and fourth to the Sport-climbing crag, I find this perfect . It has a bunch of useful features, but really has no extra crap that gets in the way.

    Comes with a rain cover, but forgive me...

    Comes with a rain cover, but forgive me ,I can't for the life of me, figure out the right way to "attach" it.

    I would say - yes, that's what it is! But I think the associate in store said it was a rain cover too? It's not a BIG deal or a deal breaker in anyway. The bag fits my painting easel perfectly (with room left over) which was the whole purpose to it. Hopefully I won't be needing rain gear when I'm out painting! :-)
