Sorry I didn't make myself clearer on what pack I was looking for JP. I'm looking at this model on the Japanese website. This model isn't available in the States.

It does have a front 5L pocket on the front for "helmet" storage. I was just going to throw in another 5L dry sack and use it for food or something.

I would be inserting these drysacks into my "river bag."

It would appear that the Backpack only has 2 pockets. I'm going to go to one of the Montbell flagship stores this weekend in Tokyo and check it out in person. I'm also going to check out the new ultralight spiral down hugger sleeping bag. It boasts a lower weight than the ultralight ss down hugger and I want to see which is more compactable.
