While I have gone to frameless packs for my three season packing, I have stuck with my trusty Osprey 60 liter Atmos for snow camping.
Now I am wondering if I can go lower that the 4 plus pounds the Atmos weighs. But I still need to be able to strap onto the outside of the pack the following items
– snow shovel blade and handle (disassembled into two parts)
– snow shoes when walking with boots
-crampons when walking with snow shoes
– trekking poles when moving with the ice axe
– wag bag
Depending on the length of the trip and how much common gear I am carrying, the pack needs to carry 18 to 30 pounds.
I fill up most of the Atmos' main bag but could probably get by if the main bag held 50 liters if the extension tube and other pockets added storage. The ULA Catalyst looks possible but I cannot tell from the photos on the web if there is room to strap on snow shoes and snow shovel.
Any suggestions or recommendations?
