Thanks Jordan!
I ran the MR Nice Metcalf for about 6 years. Sold my entire MR set up for a new Kifaru. I always had my 80mm STS on the zipper access side of the bag and rifle on the other. I would attach the Kifaru medium stove to the middle outside of the pack. It had a similar strap lay out as the Cavern, Crater and Muskeg. If its possible? I would like to see how the Cavern looks with the snow collar folded over and no top lid with about 5 days worth of gear and a Kifaru stove attached. I think freeing up that extra space in pack with the spotter on the outside is going to be a game changer! Thanks again for the help
