We started off in Europe with big 65L & 60L backpacks. I lovingly referred to them as “the monsters.” I struggled with mine but we were not doing too much walking and they held all of our camping supplies.
Sleeping bags are too heavy and bulky to carry. A good sleep sack can keep you warm while taking up significantly less space.
If you do use some, do your research and look into airport policies on carrying them on. Some airports let us walk on with them while others made us check them. Also, get a pair of gloves to prevent blisters on your hands.
– 2 dry-fit shirts – 2 pants options – I wore yoga shorts and Capri length exercise pants.
You will need a jacket. Something made for exercise but can keep you warm. Once again we went with Smartwool.
It rains. It only rained three or four days total for us and we were very lucky. Being wet was not fun. A good lightweight rain jacket can make those rainy days a bit better. Make sure it packs small!
