As a counselor at a BSA camp in Maine, I probably did a solid 2 miles of walking around every day, and needed to take my gear with me. I took this pack with me with probably around all 30lbs of my essential gear inside it everywhere I went, and I have to say over the 2 years that I have had the pack through all the applications I have used it it has been very comfortable. It has seemingly infinite space to me, there's always a place to put something if needed. Contrary to other people's reviews I find that the mesh pockets are not too small for Nalgenes, I carried two with me on a daily basis. The zippered bottom was also extremely convenient for the sudden downpours we seemed to get when we least needed them, you could just unzip it and grab your raingear. Amazing piece of equipment that has stood the rigors I put on it.

Used the pack for my flight to California,easily fit into overhead compartment. Then used it while hiking for two days in Yosemite. Enough room for all liquids, food, and extra clothing. Lid pocket good for keys, sunglasses, and money storage. Used side pockets for GPS and Cellphone. Small centered pocket good place to store trail maps. Mesh side pockets are nice, carried two extra large containers. I like the narrower fit and feel of this pack!

A great pack for day hikes and one-nighters. Very comfortable on the shoulders and around the hips, and it stays nice and cool on the back. A couple downsides are that it's just a tad small on me (5 foot 11, 175) and the waist belt tends to ride up, and the mesh pockets dont quite fit a nalgene. All in all though, it's a good pack.

Love this pack. Took it down to the Hocking Hills this past weekend and it worked great. Two changes of clothes, sweatshirt, and a fleece. TONS of utility straps and loops, many of which are reinforced. The stretchy pocket on the front held a pair of slide-on shoes and the port hole on the bottom of the pocket prevented the stink from building up too much. It's not listed in the specs but both sides have stretchy pockets as well. Perfect for GPS, knife, map, compass, or flask :) I could take this pack out for two and probably three days with plenty of room for supplies. Nice and light and the waist and sternum straps ride comfortably. Dig this pack. I'd recommend it to anyone.

I used this backpack on many day hikes in the whites and Maine
also I have used it for trips
this is everything i ever wanted and it is also a top loading pack
the only down side to it is that the side mesh pockets are a little bit too small for a Nalgene water bottle until they stretch

This is a great pack, but I found the shoulder straps and hip-belt to be a bit firm at first. I would suggest loading it and going for a few local hikes to "break it in" before relying on it for an overnighter. Don't get me wrong though, I love this pack.

I just got the pack from SAC and I have only looked at it in the living room but it seems like it will be perfect for single day mountaineering trips. I was able to fit my crampons, helmet, a few jackets, and a 60 m rope in this pack and I still had room to spare. The frame seems like it should be capable of handling heavy loads. At first appearances this pack is exactly what I'm looking for and I'm exited to test it further in the field.

I use this bag when skiing to carry my first aid kit, extra clothes, water, and lunch(I hate leaving the slopes.) It is able to carry all these things with ease. Once, with the upper lifts on wind hold, I managed to attach my skis to the bag in an A-frame. I really love it.

Hiked with terra30 up Washington.
Tthe only thing that is a down side is the mesh storage pockets.
They are a little small for nalgene bottles.
Also if you are hiking with other people the top pocket facing you can be a drag but those don't weigh down on the performance
