Ok, I already have a backpack, and know what to go for etc.

This is more an issue of size.

I’ve got a 90L backpack. massive to be honest. Maybe a bit too big. It was handy bringing stuff over to the UK to work and what not, but its the traveling bit that might be the trouble. Its starting to wear a bit – it is a blackwolf cedar banks – the daypack no longer connects to the main pack.

Seeing as I’m going in summer – there wont be a need for so much heavy items (like jumpers/jackets/pants.

So my question is do I stick with the 90L pack and leave it with lots of extra/empty room (to fill up with souveniers etc) or do I downgrade to a smaller pack size to make life a bit easier on the road?
