Thread: What size pack do I need?

I used to use an old external frame Hallmark of about 40l and managed to get by.
The I got a 90 litre for a birthday and have it bulging at the seams sometimes. I think packs are like sheds - no matter the size you always manage to fill them up.
Staying in a hut requires quite a bit less gear than camping, and having someone else along cuts down on the gear each person needs to carry as a lot of stuff you only need one.
