Overland track May 28th till June 3rd
tossing up weather to get a new sleeping bag or not. My current one is about 10-15 years old(handed down from dad), its a mountain designs tapered bag with a hood and its 100% down fill. I can not find any tags on it saying what it's rated too or the model. It lives in my swag and I've never had a cold nights sleep in it. I'm planning on sleeping in thermals/beanie and down jacket and fleece pants if need be. I've also got a S2S thermalplus liner. I've put it in a compression bag and weighed it 1.8kg.
I am tossing up weather I should buy a different sleeping bag that weighs a lot less (hoping for around the kilo mark) and one that i'll actually know the rating off.
My sleeping mat it the exped winterlite synmat, R-value 4.9.
So far I've been impressed by MONT brand
