How does this compare with the Mountain Hardware Ghost. I have looked at the specifications and most of them are close to identical. What have you heard from past customers?
I noticed the out shell is composed of different material. How does this affect its resistance to water and which one would be better protected?
I am specifically looking to purchase one of these bags for an expedition on Denali.
I've been doing a ton of research on bags for Denali and the Alaska range--I plan on attempting Denali in the next year or two. AMS (Alaska Mountaineering School) which does Guided Denali expeditions (pretty much the experts of the Alaska range) recommend the MH Ghost as one of the bag options. They also recommmend the Marmot Col EQ. I've looked at Marmot vs. Feathered Friends vs. Western Mountaineering vs. Mountain Hardware. They're all good bags, but Feathered Friends and Western Mountaineering are better when it comes down to the small details. For example, Marmot Col EQ (-20 bag) weighs 4 lb. 4 oz. Feathered Friends -40 bag weighs 4 lb. 4 oz. Also, from asking around, seems as though Marmot's Membrain waterproof shell doesn't breath nearly as well as eVent (which Feathered Friends uses) or the barrier W. Mountaineering uses. It all comes down to $$$, though. If you're spending $600+, ya might as well just drop the extra $100 and get a FF or W. Mountaineering bag.
