I used this Cocoon merino wool sleeping bag liner 52 nights on my 1100 mile walk from Dover to Cape Wrath. I absolutely loved it – it was so cosy, and warm enough to use by itself at times in the summer. It’s not especially lightweight at 282 grams but I find the merino wool controls my body temperature well. I always use a sleeping bag liner or wear clothing inside a sleeping bag to stop sweat from damaging the bag. Merino wool is best for this and will not smell bad after continuous use when you’re unable to wash it. I highly recommend the Cocoon merino wool sleeping bag liner for long distance wild camping trips. Read my Full Gear Review here.

You say the merino liner was enough on its own in summer – what do you think the comfortable temperature limit is for it on its own? Since that’s not its primary purpose, none of the shops give any indication. I was considering it as a fastpack option for some long distance runs. I sleep fairly warm and wear a layer of clothes to sleep. Of course, it’ll be down to individual comfort but I’m curious how you found it.
Hi Ella,
Interesting question. I love the merino liner because I don’t need to wear clothes in it when it’s hot. It controls my body temperature well, and also protects my down sleeping bag from sweat. I wouldn’t use a sleeping bag liner if I was going to wear clothes in it; I would wear merino underwear instead, to protect the sleeping bag. I guess the merino sleeping bag liner I have may add about 3C+ to a sleeping bag, but is in no way windproof if used on its own. You could add a breathable outer/bivvy bag and it may be usable down to say 15C, or a lot lower if wearing clothes as well (or used in a windproof inner tent) I’m not sure though, sorry.
I think the best option if you’re going to be wearing clothes is to use a lightweight quilt.
Many thanks for your message, its caused much thought.
