Hi all I'm torn at the minute between these two packs. I like the Exos for the lightweight and slightly smaller pack which should tempt me less to bring extra gear I don't need, but I like the Atmos for the extra pockets/compartments/durability. I've tried both on in a size M with weight for about 20 minutes each and they both fit nicely. The Atmos seems a fair bit dearer at £175 vs the exos at £125 which is a consideration but would pay more if I thought the pack was worth it. Thoughts? Anyone owned or tired both on the trail?
