Hi all. I will soon (in a few weeks) leave home for the CF. I have tried to pack lightweight. I changed from my Osprey Talon 31L bought in 2017 for the Portugese camino to an Osprey Tempest 24L after trying several other more lightweight backpacks. To my surprise the 24L is somewhat more heavier than the 31L. Anyone who know why? Not a big issue, just curious. Both are nice backpacks. Buen camino
