Really great day-trip bag
dakine has a well thought-out, detailed bag in the pro II. it's got effective systems for carrying skis, helmets, and goggles. it also has in insulated sleeve for your water, and space for food, layers, and avi gear.
the insulated sleeve can be a little cumbersome as you need to pull your hydration hose out to use it and then push it back up the bag a bit to zip it shut. but it helps prevent your water from freezing. also, you'd be hard pressed to get all the gear you'd need for an overnight trip in the bag. but it works great if you throw it in you larger pack while skinning out and use the pro II for you laps each day.
