I've volunteered for my regional Search and Rescue outfit and of course, the only packs I have are made out of tissue paper and weigh next to nothing. I will be doing ground SAR… and we had a serious hurricane here a few years ago… so I imagine there will be a lot of deadfall to climb over, wiggle under, push through, etc.
Since I started out from day one as an ultralight backpacker, the only packs I know anything about are of the tissue paper variety (GG, MLD, etc.). I could just go to the local MEC but I think that might be the other extreme… bomb proof packs that weight 5 pounds empty. Surely there is a middle ground.
Any recommendations for companies and / or fabrics to look for? We may sometimes be called upon to be self-sufficient for an overnight… but never longer than that. Most of the time we would just be on 3-4 hour tasks. So I wouldn't have to carry a TON of gear.
