Arc'teryx Miura 30 Backpack - 1831-2136cu in

Solid bomb proof pack made for days on the rock. Love the organizer features in this pack to keep my gear sorted.

The quality of workmanship, stitching, straps, buckles, etc. are all excellent. The roll/fold down top is adds strength and durability and the overall full zip setup is great. The bladder pocket is snug and I was afraid I might tear a seam as I jammed my 3 liter reservoir into it, however I was able to get it in and all the seams appeared to be holding well. The snug fit will probably stretch a little and loosen up with time making it easier to store the bladder in future, but the compression it provides will probably always be there ensuring excellent water flow through your hose. Again, the construction is extremely durable and aided me much on my most recent trip to Nicaragua. Completely stuffed my airline didn't give me any trouble carrying it on and although on my national flight it took some effort to stuff it into the overhead bin. Even with this harsh treatment and tons of truck beds, sandy boat bottoms, and rough use as a backrest against trees and boulders, the nylon exterior shows no permanent scuff marks.

The pack is as it appears. If your leaning towards the larger size, go for it. If your not in need of the extra space, this pack served well carrying three pairs of clothes, a henessey hammock, sleeping bag liner, and full size DSLR.

Theres no doubt in my mind that this pack would last years of abuse. The pack is made with burly materials.
The design is unique and takes a bit of getting used to.

The main compartment is big. I loved to idea of gear loops, although I never use them. The bottom of the pack is a kinda weird shape, and you have to shove your gear down there to make it really take up all the space. I love how you can just rip this pack open and get access to all your gear, it also packs up very quickly. BUT its hard to stuff a bunch of gear in this pack, unlike a lid closure you have to stop loading the pack at a certain point so you will be able to close and secure the straps.

Also like the external straps, great for overstuffing the pack and then strapping a rope to the outside.

The external jacket pocket is the perfect size for a puffy.

External key/misc pocket has generous space for all kinds of randoms you carry.

Suspension system is pretty good, although the hip belt is huge and is noticed on high steps and scrambles.

Overall I am liking this pack, and the only reason im really giving it 4 stars is for the fact you cant cram it full of stuff, and the hip belts are just a bit too big.

This bag is awesome. It will take almost any bullet you can shoot at it--by bullet I mean serious abuse from sandstone, granite, etc.

If your looking for an ultralite bag this is not it, but then the muiras are designed for situations and abuse that would instantly vaporize an ultralite pack.

The features are fantastic. I love that the pack completely opens down the side so the whole front of the pack folds down. The gear slings on the inside are a great touch. The belt provides good support and holds the bag tight against your back without getting in the way. The roll top is just cool and is easier than unclipping and removing a top pouch to get into the main compartment. Also the roll top does not get in the way of the top pouch that is there. The removable rope straps are great for attaching lots of rope and it's nice that they can be moved from the back to the top of the pack for comfort or preference.

It is a fantastic bag for the approach hike and depending on how much climbing (or canyoning) gear and rope you need to take I find that 30-35 liters is good for between 2-4 days.

All in all i think it is my favorite bag of this size that I have ever come across.

Arc'teryx does it again . . . of course the Arc'teryx awesomeness also comes with an Arc'teryx price tag . . .

Just got this recently and got outdoors just today with it for the first time: It's pretty sick! I got the large one and I could fit my 60m rope (put in a metolius rope bag), shoes, kneebar pads, harness, cinch, and belay gloves in the main compartment. On the way back I managed to stuff my hoody as well. So that's enough room for a day at the crag.
I didn't get the strap issue the other review mentioned. But yeah the bottom of the bag is a bit narrower, I guess for the style, which I don't mind really.

I'm a huge Arcteryx fan - I have jackets, clothes, packs from them and until now, I've never been disappointed. On the good side, this pack is well made and is likely to last a long time. The hip belt is comfortable and the adjustability of the straps etc... is great. The buckles, stitching are all top rate.

But there are a couple problems. First, when you roll up and then fold down the top of the bag (which makes it pretty weather-resistant - nice!), the straps holding each side down don't pull the folds forward enough, so when you walk with the pack on, it rubs your shoulder/back of your arms. That's not a good design for long walks.

Also, the bottom half of the pack's large storage pocket is strangely small, as if the material is cut narrower there. It means you have to think hard about how you plan to pack. It just seems to be smaller than I expected it to be.

I have the green one and I really like the color - not as loud/neon as it looks in the pictures.
