nice
this bag was exactly what i need for a weekend or a few days trip. its small so after having your tent and bag in it their is only a little room for clothing, gear, and food. i back country hiked in the Smokeys for 6 days with it. rained and snowed on no problem. didn't even have a shell on over it. would recommend it to anyone. best suited for climbers with all the added luxuries to suit them.

Great pack for what its desgned to do
Again, Osprey has come up with a great pack. Think of this back as a gym bag for climbing. it doesn't have lots of pockets or quirky use less stuff. it has just what you need to get your gear to your climb site and back. the fit is great and very comfortable. there is enough room in the main compartment for your rack, rope, harness, crampons, and extra layering gear. the top is easy to adjust for different size loads and has a couple or really nice pockets to keep smaller gear close at hand. If you are someone who likes a separate pocket for different gear, this is not the pack for you. This is also not as good of a summer pack as other osprey designs, as the back pad is a closed foam type to keep moisture from soaking in when you put it in the snow. All and all a great pack that I highly recommend for your next ice trek. love the haul loops by the way and the waist belt lock system to keep the belt out of the way when wearing a harness. its on of the main reasons I got the pack and its worked well.

Osprey Design + Altrec Price= greak pack
I bought this for one of my sons after researching lots of packs. At 38L it is perfect for three season backpacking and climbing, with expandability for winter sports. The removable bivi pad and frame sheet make this back double as our go-to day pack: Z compression helps there too. Simple and impressive styling round out this great pack. Only one issue is the Hypalon racking loops, they are more work then necessary, a simple rack would have made this pack 5 stars.

Sizing Chart
Osprey Packs Sizing Chart
Step 1 - Pack Sizing
All Osprey packs, save the transit bags, are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).
Step 2 - Hipbelt Sizing
To determine your hipbelt size measure around your hips, not your waist. A properly fitted hipbelt rides centered over the hipbones and needs to be very snug; after all it will be carrying the bulk of the pack's weight. The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the pads when securely tightened.

ErgoPull
Nearly all Osprey hipbelts use an exclusive ErgoPull design. It creates mechanical advantage to provide extra leverage in cinching down the hipbelt. The ErgoPull design also draws tension along the top and bottom of the belt, not through the center, so it distributes pressure more evenly over the padding and relieves direct pressure on the hipbones.
Step 3 - Harness
Osprey Crescent & Luna, Aether & Ariel and Waypoint packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size, but your best bet is to try one on. A properly fit harness should terminate 2 to 3" beneath the armpit. Webbing should not touch the body. By breaking the hook and loop connection and sliding the harness up and down the backpanel the torso length can be adjusted up to 3". (see illustration).

Step 4 - Overall Fit
Once you have the correct size pack, harness and hipbelt, and the torso length set properly, it's time to put some weight in the pack (20 to 30 pounds of well distributed weight will do) and dial in the fit. First, snug down the hipbelt and harness. Connect the sternum strap (A) - position it about 2 inches below your collarbones and snug it down lightly. Finally, tighten the load lifter straps to draw the load solidly against your back. The lift straps (B) should come off your shoulders at a 45 to 60 degree angle in Osprey's ReCurve and Ethereal Suspension packs. In other models these straps serve more as compression straps and ride flatter; they may even angle downwards.
In a good fit, there should be no pressure points and no gaps between your body and the pack. With Osprey's ReCurve packs, final tweaking may involve custom fitting the aluminum stays to your back.
