Just bought this pack and it's awesome. Perfect size, not too bulky and still fits everything you need and has a low profile so it stays close to your back and is pretty easy to get on lifts with. It fits a water bladder without a problem and the insulated sleeve works well. It's nice how you can open it fully it makes it easy to access everything. It can fit a shovel, probe, extra goggles, gloves, hat, shirt and bladder without a problem. If you're looking for a low profile pack that will work well in the backcountry and can also be used without a problem at the resorts this is the way to go. Avalung is always a plus to have as well.
