I can't find anything about this pack that I don't like and appreciate. I have backpacks by Marmot, Mountain Hardware and Millet. In Osprey I have an Argon 85, Atmos 65 and this Kestrel 48. One thing I've grown to appreciate about Osprey is the build quality and attention to detail. The Kestrel 48 is the perfect over night pack, although you'll be pushing space limits if you're overnight is in the winter. I don't like to strap a bunch of gear to the outside of my pack so to me, this is a 3 season overnighter. The Kestrel is really versatile and would even do ok as a technical pack. There are two side pockets that would handle crampons and skins and there are proper straps for hauling your boards in an a frame or straight up. There's no dedicated space for avalanche gear or helmet but that's a small price to pay in a pack that is loaded with so many creature comforts and organizational pockets for straight up back packing. The external hydration sleeve is very nice. No more rummaging through your gear to access the H2O. Plenty of compression straps on the side make it easy to secure smaller loads. The sleeping bag compartment is nice as is the rain cover. A 48 liter pack is a versatile size that will get lots of use and this is the perfect example. Flawless.
