This is the middle big pack (middle bag size ) of the 3 biggest packs! How's that for fine tuning? Beginning with the CMII The packs increase progressively in size by one inch of circumference. We can help you decide. This truly is a big EXPEDTION pack. Like the other CM packs, the MB is untouchable in load carrying capabilities. Below: A Dyed Full Dyneema MB-CMII. Click image for blowup.

Dan,

I just got back from the trip that my MB CM II was built for. Before the trip, I made a few minor adjustments to the stays, and after that no fiddling was necessary. The pack performed above and beyond my expectations. With my old pack, carrying anything above 50 lbs would wreck my shoulders by the end of the day. In contrast, I was able to carry 80+ lbs (3 bear cannisters, camping gear and climbing gear) in the MB CM II for up to 13 hours in heavy brush and through lots of talus without any shoulder pain or collarbone soreness. After living out of the pack for more than 3 weeks, it becomes very clear how well thought out your design is, and the attention to detail is appreciated.

Regards, Yoav
