Silk bag liner?

Post by jamiep »

Decathlon have one for only £25 that is only 110g. Do these add warmth and worth the but of extra weight? Or gimmick? And I was thinking it could also be useful with just a bivvy bag for a summer long audax brief kip

Although a silk liner will add some warmth, you'd be better off buying a thermal liner or better still a sleeping bag with an additional 110g of down in it :wink:

While that's true from a warmth perspective, I think they're useful if you're manky and don't want to get your expensive new down bag the same. Saves having to wash your sleeping bag as often (which helps it last).

<Edit> would need to be pretty warm in the summer for the liner to work on its own. Might be ok with a warm jacket though.

I always use one on a race for the aforementioned manky legs reasons, but they do add a bit of warmth too. I wouldn’t use them with just a bivi though as the windchill would remove any benefits.

Perhaps look at a SOL Escape for emergency use as it’s about the same weight as a bivi and liner?

Bought one of those from Decathlon this Sept and used it during TNR. My bag is on the limit on that ride higher up and the liner did seem to help. Not particularly warm but worth it for cleanliness and a couple of degrees (?) bonus. Feels like a good buy for the money.

Also been thinking about Audax kip kit recently, the liner doubled up on my lower half, a jacket and a light bivi bag would be ok for an hour or 2, not bad at ~300g plus the jacket. Will prob just go with the jacket though. Power naps not sleeps.

The Decathlon one's decent. Some good ones on ebay from Hong Kong too.

Based on the absolute state mine's been in a few times after bivvys it's definitely worth having one to keep your bag/quilt clean.

I always use a silk liner. Dirty down loses its effectiveness pretty rapidly. Frequently washed down is similarly affected. Any additional warmth/insulation provided is only a welcome side effect.

For very frequent outdoor sleepers I fully believe in liners, but stopped using silk as it would last only a year or even less.

I often am quite dirty when I sneak into the bag/quilt so I use it mainly for keeping the worst of muck from my down filled lovelynesses.
My self made liner weighs a scant 60 g.
From experience I can say that with it's use I can squeezes much more use out of the sleeping kit.

My self made quilt - 2.5 y old - has seen 140 - 150 nights and besides smelling like a salami is still going quite strong. Will wash it for the first time soon. Before liners my sleeping gear needed washing after about 40 - 50 nights.

I like getting out of my biking kit ASAP once I've stopped otherwise I get cold quite quickly so carry a lightweight set of thermals, pyjamas effectively, does the same thing regarding keeping the dirt on my body from getting into the bag.

I do have a silk liner but it can get quite twisted up around me :oops:

This

Apart from a good airing and the occasional wipe down with a damp cloth, this is how I keep my sleeping bags clean.

Thats exactly what I do. It also means I can have evening attire that is dry and so I can chat/socialise/wander as appropriate

I'll often wear wet socks and leave my feet in my shoes, unless they're properly soaking, and warm/dry/talc my feet before putting bed socks on and getting into my quilt/bag

Ah! I forgot the "wafting" :grin:

Ben, talc on feet is worthwhile, the state of my feet after the HT550 wasn't nice :o

That's a very impressive ratio of time spent under the stars!

When using my down bag, I always take warm wool bed socks (115g), and either a silk liner (trimmed slightly - 90g) if going minimal, or HH merino 'evening wear' (385g for top & bottom) for colder or more sociable rides. Add a synthetic balaclava (40g) and down booties for cooler conditions (95g) - my feet get cold quick, so better to do this than take a warmer bag. Won't bother with a liner if using the 1 season synthetic quilt, as it's easily washed.

I've got one. I don't remember it costing that much!

Essentially it's the same material as a synthetic base layer. So it's does add some warmth* but is heavy/bulky and behaves like a synthetic base layer if it gets wet or you sweat in the night.

I tend to take a cheap cotton** liner for the keeping the dirt off purposes and leave my bag to do the job of keeping me warm.

*I think. It wasn't consistently warmer but there are frankly too many variables to take into account (length of ride, food consumed, type of shelter, exposure of pitch etc. etc.)
** I think it's cotton.

I have one of those decathlon liners. It's ok, but mine has ripped quite a bit from me trying to get out of the thing. As others have said - its good for keeping the sleeping bag clean and does make a fair bit of difference warmth-wise. We just use our silk ones in summer and have reactolite liners for colder weather.

Where did you get your down booties zerodarkbivi? We camped out in frosty weather last night and I def need some.

I always wear jim jams so it wasn't about keeping the bag clean but about a warmth boost. And the option of a light audax power nap system. Seems there are ones for a tenner in eBay so I'm gonna give it a try

Montane do some quite nice synthetic filled ‘hut slippers’ too

I got those as felt that it’s a better material for footwear.

It's worth noting that the standard for sleeping bag temperature ratings, EN13537, assumes that the individual is wearing some form of thin thermal layer. I believe the actual garment used is a track suit.
