I saw first saw this pack in a local shop, and I was mostly intrigued at first because of the brand's reputation. After checking out some bits on the internet about it, I snagged this pack and awaited some opportunities to use it.

The pack takes a while to properly "understand" and fit to your body so the weight sits centered on your back and doesn't cramp your left shoulder. I discovered that the waist-strap buckle can be slipped through the large D-ring which connects the waist-strap buckle to the shoulder strap. This shifts the waist-strap from behind the D-ring to the front of it, and this makes the pack substantially more comfortable (for me). The pack, otherwise, is adjusted by tightening the shoulder and waist straps and remains set in place quite well. It's easy to forget that there's a pack on your back even after a looong day.

There is a bit of a learning curve in figuring out how to pack the Quiver due largely to its irregular shape. I was troubled at first, but after a week or so of random town adventures I became a pro, and realized how well the pack accommodates cramming and stuffing. The zippers are sturdy tough stuff and the pack itself seems to encourage the zippers to close when its packed.

I've used the pole-strap clips sparingly, but when the load is wide enough, there's no way they can come unclipped without manually unsnapping them. One downside is that there is a clearly defined limit to the diameter of what they can hold, as the shock cord/plastic apparatus absolutely refuses to stretch beyond a clear, well-defined limit. Clever working, however, can allow the clips to accommodate anything from a machete to a shovel. There are other ways Arc'teryx could have implemented a feature such as this, but by no means are the clips bad or useless.

The hydration slot within the main pouch is cramped and is hard to fit my 2.0L bag into; however, it can be inserted in there overloaded well past the marked "full" capacity if the camelbag is completely placed inside the pouch before one attempts to slip it into the (very tightly fitting) sleeve. The opening for the hose it also very tight. Shock cords which sit on the back of the shoulder strap just above the pack can be used for whatever the user envisions, but are useful for guiding the hose. There is also a rubber O-ring which is clipped onto the lower shoulder strap to stash the business end of the hose.

The last thing worth mentioning about this pack is how easy it is to access the pack's contents while still wearing it. Just unclip the waist, slip it under the right arm, and it sits comfortably on the chest, and zips back easily even with cramped loads.

Overall, I would give this pack a 4.5, but that's not possible and I don't think it deserves a 4 because of how swift and easy the pack becomes after a small learning curve. It can even be slipped onto a large backpacking pack and kept centered by virtue of its own straps. I have no major issues with this pack, and the only complaint I could register would be that there's no sub-compartmentalization within a pack to keep something like keys or a wallet in a definite location. This, however, is extremely minor and can be worked around just be keeping a small baggie inside for such things.

I got the Terra 60 to partly replace a 5600 cu. in. Kelty bag I had (which I can't complain about it all). I just wanted something smaller and sleeker, since I would get myself pinned in dense shrubbery while going off-trail with the bulk of the larger Kelty pack, and I felt that 5600 was silly overkill for a night or two out. I really would have given this pack 4 1/2 stars if it were allowed.

One of the main reasons I picked the Terra was the stretchy material the side and back pockets are made from, which is durable and protected by some incredible zippers.

The main compartment is, of course, top loading and has a bag division at the bottom; however, this is something to nag about... as the divider itself does not zip shut within the bag; rather, it has 3 elastic loops that connect around oblong connectors. It serves the purpose well if you happen to store like things together in their own organizer bags (clothes in a compressor, tools in a mesh, food in another bag, etc.) If you are ever in a hurry and don't do this, though, expect your items to wind up in the sleeping bag compartment, promised.

There is a spot for a hydration bladder with a well-designed hook, at least for a name brand Camelbag. I'm not sure if it works as well with other brands, but I'm sure it does. Also, there is most definitely a hole for the hose to come out of the bag (as some of these reviewers have not been able to find...), but it comes out near the left shoulder, which is unusual but it's not an issue. The hole itself is pretty tight, and if you have any hardware on the end of the hose, it will have to be removed to pass it through the hole.

The top pouch is fixed to the bag and cannot be removed for use as a day pack, and it is fairly small. I usually stuff this part of my other bag full of things I might definitely need quickly: rain jacket, gloves, toilet paper, med kit, etc. I can stuff most of what I would like in the top, and the rest is able to fix in the stretchy side pouches, so this is really not too big of a problem.

Water bottle mesh pouches on the bottoms of the sides are large, accommodating, and have shock cord loops attached to them, of which I had one outright fail on the maiden voyage with this pack. The little clips that attach the free ends of the shock cord somehow came unclosed, and I was able to fix this, but it seems that it could happen again, so I don't use this particular function of the pack.

My biggest problem with this bag, though minor, is there are no bottom straps to attach a sleeping roll. For the life of me, I can't figure out why this wasn't added. What designer thought this pack was big enough to stash a sleeping roll inside? There are 4 loops on the bottom of the pack that one can pass his own straps through to mount a pack (which I did), and it works just as well; however, it still is bothersome that this was not something that was already on the pack.

The size medium bag fits me very well; I am a 5'7", medium build guy, and after some very minor and easy adjustment, this thing sits on my hips like giving a supermodel a piggy-back ride. All the adjustment straps were well thought-out and have loops at their ends for easy tugging.

Aesthetically, this bag ain't half bad to look at. I've received many compliments and it has helped to convinced some of friends who are newer to the adventures of backpacking to get large packs too. I personally chose the cave black color, and its green highlights look amazing in complement, especially given that my bedroll is a thermarest with a matching bright green stuff sack.

In conclusion, there were 3 minor problems with this pack: the sleeping bag compartment divider, a shock cord failure, and the lack of built-in straps to accommodate a bedroll. These three things are all minor, and hopefully will not deter everyone who reads this, because this pack is otherwise amazing to wear, sleek to off-trail in, and spiffy to look at.
