Sleeping bag liners

[Tomwoodbury]

So…. Some of you may have seen my quilt for sale on here which I find a bit chilly on colder nights. I was wondering if there was a sleeping bag liner anyone could recommend that would be able to make the quilt usable once the temps drop. Is there such a thing that has a comfort rating “upgrade” stated.

Cheers

Yes but I wouldn't believe the majority.

A thin summer sleeping bag beneath the quilt will likely be your best bet.

I use a sea to summit reactor which does add a bit of warmth.

Which sleeping mat are you pairing the quilt with?

I asked a similar question at the start of the year. If I remember correctly the general consensus was that while some would help by a few degrees, some of the claims were pretty optimistic. Joe's shop had a budget thermal version, not tried it though.

Thanks all. I have a thermarest neo air lite or something like that. It’s paper thin almost, so maybe that’s my problem.

Tbh I think a thicker quilt is the answer as I don’t want to carry multiple bedding items and I hate the bulkiness of bags on the bike.

A quilt won''t really work without a decent mat. The 250 is a cracking piece of kit that's easily supplement with a few clothes as temps drop in the "shoulder" seasons, if necessary (IMO/E).

If it were me I would get another mat as whatever quilt you get there is nothing else stopping the heat loss to ground and you risk having the same problem. heck someone local to you might lend you something to try.

I'm a big fan of Exped stuff and don't know the neoair mats very well.

Edit: if it's the same as the one I just googled then R=4.2 so maybe it's not the mat

SOL escape bivvy not the nicest next to skin but i sleep in clothes so not an issue - also allows you to get in filthy [or damp] and not dirty [wet]anything
Lighter than most of the other options and not that spendy

I've never got on with a bag liner, they're so annoying when they wrap around your legs and get twisted in the night, I prefer to pack separate merino base layers for sleeping in.

^ yep

Exactly my experience too. And not really any warmer in my (limited) experience.

Ditto ... it makes the horrible cold liner they seem to love in sleeping bags more bearable !

[Bearbonesnorm]

Out of interest, did / do you strap the quilt to the mat? I find that sometimes, it can cause the quilt to 'pull tight' which can flatten the insulation and cause cold spots.

[Dave Barter]

Just to say that I use a bag liner in all my bags (don't like quilts) not to keep warm but mainly to keep the bag cleaner as I'm invariably very stinky when I get in it.

To add warmth I'd be inclined to wear a down jacket/ gilet or thermal base layer. I love my superlight down jacket which takes my cumulus 200 bag down to a very comfortable 0 degrees.

Without the jacket it would be comfortable down to 5 or 6 degrees.

Even a very warm sleeping bag or quilt (also with down clothing) is only as warm as the mat you're using it with.

I try to find places with a soft ground that will trap some air like a field or open grasslands or a forest with loads of leaves or needles rather than naked dirt, rocks or snow.

Same here. Mine is a selfmade 7D Nylon bag to protect bag/quilt from dirt. Full length and weighs 60 g. Must be about 9 years old and despite the very light & thin fabric
& not taking care, it's still fine.

Is anyone using any kind of reflective or foil ground sheet with their mat?

I use a Sol brand emergency blanket as a groundsheet underneath the tent inner but I imagine it has almost zero effect on boosting the warmth of my bag-air matress combo. I use it mainly cos its 100% waterproof, lightweight, cheap and means I'm always carrying an emergency blanket should i or someone else need one.

My mat has an R value of 2.3 which is pretty decent, no?

I think that would class as a 3 season. Do you take a spare set of baselayers to sleep in?

[Tomwoodbury]

Yeah, tend to sleep in trackie bottoms when it’s cold.

Folks, remember that EN/ISO* sleeping bag ratings assume that you are wearing some form of base layer. From memory I think the standard (actually a criterion) uses a track suit rather than thermals.

*EN13537 is now ISO23537 (ISO adopted it in 2016)
