These are solid, the only negative is if you have for skiing at all, make sure there is no water in the nozzle, it'll freeze up fast. just blow air back into the line & you'll be all set. If you try softly chew the ice to get it free, the rubber will rip & water will leak out. This why it good to keep a couple extra in your pack. I like the Black Diamond & Mammut skiing packs,they have camelback zippers on the shoulder strap so it'll have a less chance of freezing up.
