Greatpack for snow touring / ice climbing gear carry - Mountain Hardwear BMG 105 OutDry Backpack

I read a comparison story featuring this pack being taken around the world to various climbing locations. It was an impressive promotional piece.

I bought this pack for the waterproofing and large size. I had previously used a 70 litre Mammut Trion pack for snow touring. But on the last trip I was rained out and the pack contents (not in dry bags) were soaked despite a rain cover and with all the ice climbing gear, weighed down with things hanging off a too small pack.

I have only used this pack only once for an extended snow camping and snowshoe trip where I carried in a lot of weight. Given the simple big bag shape and lack of moulded body forming design, I expected it would be uncomfortable. But surprisingly it wasn't. In fact it is the most comfortable pack I own and I am not sure why. From the look of it you would expect it too be unwieldy when fully loaded to 105 litre capacity but it sits well on my back, maybe because it is wide and fat rather then thin and long.

Anyway, I would recommend the pack for its extreme waterproofness, lightness and carrying capacity.
