I've changed packs for this kit, moving it from a day hike sized backpack to my 60 litre Jack Wolfskin pack.
60 litres ... wow, that's a big daypack! I've been starting to look around for a new daypack (my current one is just a bit too small), but I've been thinking something more like a 30 litre bag would do the trick. I have a 70 litre bag, but that only comes out for multi-day trips.
I'm curious, how big are most peoples daypacks around here?
