I like to use a cover on my bag on my winter adventures, more to keep my bag clean than anything whilst in bothies. I use an Alpkit Hunka. I was wondering if there were any lighter weight options, as I'm not planning on sleeping outside in it. The Hunka is about 330g. and I have seen a PHD cover at 154g which looks like a good option - if a little expensive. Any ideas, for something lightweight, compact which doesn't involve rustling like a bag of crisps. I dare say I could simply do without one and save some weight, but I'm happier keeping my nice yellow bag clean : ). and the hunka does give me a level of extra protection too in my tent.
