So I am looking for a da ypack to fit into my Arcteryx Bora 80. Will the medium be too large to use as a day pack when I am 11 miles into the wilderness?
For a day pack that will pack down to almost nothing, try out the Mountain Hardwear Scrambler Backpack:
I've never owned it myself, but a coworker of mine who I spent several weeks with in the Windrivers swears by this pack, and me and my fanny-pack were always a little jealous of his good style.
Or check out the Marmot Kompressor Plus. Packs down to almost nothing and crams in just about anywhere. I like it better than using the lid from the Bora 80 as a lumbar pack for sure.
