If you're a mainly piste skier looking for a rugged daypack with a relatively simple but effective design the Capstone 22 is a good option.
With a 22-litre capacity you can easily get everything you'll need into the single main compartment, which has glove-friendly zips and comes with a hydration system sleeve (although note that there's no insulation for your hydration hose so it will be liable to freezing up in colder conditions), and there's also a small zippered outer pocket with key clip for stuff like goggles and sunglasses.
In addition you get a large, expandable panel for additional outer storage, and there's a walking pole holder for summer use.
The Capstone gives a comfortable, stable carry thanks to a tensioned mesh back panel (which also provides good breathability) and a well-padded, wide hip belt and shoulder straps. The hip belt was one of the best on test, and it also has two small mesh pockets, one zipped, the other not - the non-zipped pocket we'd be reluctant to use as anything in the least bit bulky is liable to slip out of this.
The womens' model of the Capstone comes with a female-specific harness and hip belt, so make sure you go for the right model if ordering online!
