We went out to a local sports store called Decathlon and bought 22L and 30L bags with hip straps and sent our monsters (with most of our items) home.
Sleeping bags are too heavy and bulky to carry. A good sleep sack can keep you warm while taking up significantly less space.
You will need a jacket. Something made for exercise but can keep you warm. Once again we went with Smartwool.
We went with The North Face Hedgehog sneakers. (They have male & female versions.) They were perfect for us. If you do any research for this trip, make sure to do your research for your shoes.
My recommendation is Smartwool. They were thick, kept sweat away and protected my toes and heels.
Your feet go through enough. Do not add athlete’s feet to your laundry list of pain. Small lightweight shoes will save you.
