Evolution Revelation rated for 20, wide cut. Packs down small.
Six Moon Designs Trekker. It stays in the large side pocket.
I hope I never have to use a bear canister. The Norwegian/Swedish bears hasn't developed a taste for Snickers... yet.
Yeah, it is a bit of a squeeze. Find myself considering volume AND weight.
On load lifters:
It appears that the Gorilla 2012 does not have them.
Checked my order and the site now. I have a Gorilla 2012 and the pictures and specs on GG shows no load lifters. Yet my particular pack has them - they even work. So I guess I got some sort of hybrid or test product. No complaints from me :)
... or you know, locking closer at pictures, I think van Peski may have sent me a Mariposa... two pocket on the right, one long pocket on the left AND load lifters; that's my pack alright.
Well, that answers your question, then. The Mariposa has rather more volume than the Gorilla. Which means I am doing something wrong when packing.
20 hours later...
Scratching two compression sacks as per BPL suggestions and fiddling with the compression straps left me with room for a couple of six packs - if I where so inclined.
So with the right gear, the Gorilla might be a perfectly good seven day pack, but the Mariposa is a bit more flexible.
