Very comfy. Lots of pockets. Cool trampoline back (more air than the bigger Jades) to keep to prevent sweat... rigid X-stays which makes it easy to carry. 2 mesh zip hip pockets. Hipbelt feels great hugging hips and putting the weight onto my legs and off my back. Adjustable shoulder straps, load lifter, and chest strap. Front vertical pocket, a drawstring top covered by a top cap with zip on top and underneath (bigger Jades only have one on top) Has a fully separated bottom compartment, unlike bigger Jades... too small for a sleeping bag but maybe a sleep sack or other quick access things. Vertical zip quick access pocket, a horseshoe zip for accessing the main pack quickly without undoing the drawstring and top lid clips, to get something small out. Mesh pockets on the side good for water bottles and the compression keeps the water bottles secure so it doesn't fall out or rip pockets. Unlike bigger Jades, it comes with a rainfly in its own compartment. Standard hydration pocket, two loops for axes, walking pole loops. Top is not detachable like bigger Jades, and there aren't any sleeping pad hookups for the outside (like bigger jades). Comes in S and M, no XS, I use the XS in other Gregory, but this one in S feels fine. Not an adjustable back length like Osprey. Narrow profile so it's a bit lengthy, so if you have a helmet on it might be hard to look up, but not horribly restrictive. Use this for climbing, not backpacking. Haven?t had to carry all the gear plus a rope, but I think it can. Roomier than my bookbag and doesn?t feel like the zipper will burst. If I were to backpack with a tent, sleeping bag, and climbing gear I'd go w/ a bigger pack.
