I just watched a YouTube vid on sleeping bag liners and thought what a hassle this guy is making getting in to it!
So I thought I'd ask what others thought of liners and what they actually wear when in there bag, I my self dont use liners i just wear a pair compression tights and ls baselayer which for me keeps me roasting hot as I am a very hot sleeper, would any one else like to share there night wear with us?

Merino Leggings and shirt with Rab Down Socks, depending upon bag maybe a beanie too. Same as setup regardless of location, just use different bags! The only liner I've ever had which I can rate is a Macpac Down Liner, discontinued now. Also works great for alpine hut climbing on it's own.

Helly Hansen Lifa top & leggings
Down Jacket if it's cold
North Face hat

would any one else like to share there night wear with us?

I tend to kip in whatever I rode in minus outer layers, will stick a down jacket on if it's very cold. Can't be bothered with carrying spare clothes just to sleep in.

Others tend to carry some rather special sleeping attire ... here's flatfishy getting ready for bed on a trip earlier this year

is that outfit waterproof, and he no longer requires a bivvy bag?

Wait til you see this years!!!!

Depends how cold it is!

Normally some fetching Y fronts but if it's cold, i've slept in a trackie bottoms and a fleece. Have just bought a thermal base layer for my Xmas jaunt.....

I always use a liner to protect the bag and keep it clean. Other than that it depends on how warm/cold it is. Anything from naked to Patagonia capilene bottoms, Craft ls baselayer and Ibex merino beanie and socks.

Last summer a couple of times I was so tired I got into my bag in my riding kit. Great Basin and Gila Wilderness were two I recall.

Another Lifa base layers user here, with M&S merino socks to keep the sleeping bag nice and clean. If I'm wet I'll change into the dry sleeping/evening wear once I'm camped up; for me this is the main advantage over a silk liner.

I have a down vest, down jacket and a fleece beenie that Ill have with me depending on the season. My winter bag is -18'C so its rare I need to boost its warmth though.

In the bivvybag I'll often also wear a headnet (read headnet not hairnet ) to keep the slugs/earwigs off!

Told you so ^^^^
