Here's my packlist for EBC, for what it's worth. About 7 kg in your pack, 2 kg on your body. The magic is the wool. It doesn't stink up when you wear it, so you can pack fewer clothes. Carry no blades, The ULA pack is under the size limit for carry-on, so it comes with you on the plane, no need for baggage check. Have fun. PM if you have questions.
ULA CDT 35- liter Backpack
