So generally these don't go together if you're doing SAR you're carrying far more gear than you would for ultralight. However due to a tiny primary residence. I need to really condense down to one pack for SAR, backpacking, and lower key Alpine touring and mountaineering.

Looking at the 60L Mariposa from gossamer gear. Z pack arch haul 60, and hyperlite Mountain gear Porter 70. I don't need the pack to be the best at any one thing I just needed to be a good backpacking pack first and a serviceable pack for other activities

I won't be doing rope work, and generally we'll be carrying a small first aid kit, I am required to carry a foam sleeping pad, large poly tarp, and everything else you would put in a 48-hour pack for sub freezing temps winter conditions.

I would like a pack that would allow me to carry poles, one ice axe, and possibly touring skis or snowshoes. Those items aren't for Search and rescue there for recreation

I'm not sure if this is a realistic ask. But I figured I could at least try.
