I've owned a Cold Cold World Chernobyl for the better part of 20 years that is finally calling it a day. I'm looking for a replacement pack pretty much for winter day trips. Whilst the CCW pack was outstanding, I seek something with a little more back support, either a plastic sheet or AL stays. If Black Ice Podsacs were still available I would jump on the chance to buy one, but unfortunately they are long gone. I've drooled over Hyperlite ice packs but am hesitant because of the horrific cost as well as the durability, abrasion resistance of the dyneema (cuben fiber) material. Any thoughts, comments, first hand experiences would be greatly appreciated. Thanks!
