Just thought of a solution - buy a double sheet and get a seamster to stitch in half. Not so difficult was it! LOL.

Double sheet is THICK.

Thought you wanted thin.

Why not DIY?

My upcoming winter trek makes me interested in this thread

What was the outcome? How did it work out?

A cotton sleeping bag liner is available at most Decathlon stores.

A silk sleeping bag liner is better than cotton (lighter / warmer / easier to dry) but I haven't seen one in an Indian store. However it could be easily fabricated by a neighbourhood tailer and using the cotton liner as a template.

Can be easily made from a Kashmir silk saree, perfect size - but make sure to have real silk and not a synthetic pseudo-silk...

Oh well... I shall check in the Noida Decathlon store next week. I understand silk will be better than cotton, but will cotton liner be good enough?

Good enough for?
perhaps if you should state your intended use and I might help with a more useful reply...

I have a Wildcraft bag that works till -10 dec C but is now a few years old. I am not sure if the fillings have still got it in them to keep me comfy at -10. For a winter trek where I expect -10 deg C, I want some extra protection from the cold. Hence looking for a lining (besides, of course, thermals and chemical warmers).

Another use, I am wondering about is washing! Would it be less of a hassle to undo the stitches of a lining, wash it, and re-stitch it to the bag?!

Ok here goes.
A sleeping liner has 2 purposes
1. Warm(er). A good silk liner will add an extra 3 deg C to 5 deg C to the rated bag temperate
2. Clean(er). By ensuring your skin oils or dirt from form your clothes doesn't affect the insulation. Remember a cleaner bag is also a warmer bag.

For a winter trek I would insist on a silk liner. Silk wicks moisture better and is easier to dry as compared to cotton.

Digressing: For a cold weather winter trek I would refrain from taking anything (clothing / gear) made out of cotton. Second, AFAIK and I may be wrong here, wildcraft is an indian company and its sleeping bags are made out of synthetic fabrics and not down. I would have serious doubts about a synthetic sleeping bag keeping you warm at -10 C. Have you tried this bag earlier at such temperatures? If not, invest in a good down sleeping bag for winter treks. And yes, good down sleeping bags are expensive and no, you will not find them in India.

P.S. before you wonder why this crazy guy is berating you for your choice of gear, I have done almost every established winter trek in Himachal, Zanskar and Nepal.

I hope you carefully think about my advice and I hope it helps.

In my humble estimation a cotton or silk liner isn't going to do much for you, considering the temps you'll be encountering. Also understand, if you don't already, that if this "-10 degree C" bag of yours is "Guaranteed" by the manufacturer to -10-degree-C . . . it ain't necessarily so. Manufacturers can play very free and loose with temp ratings.

Have YOU used this bag in -10 degree weather? The REAL rating of a bag is what YOU can put up with.

And no, I wouldn't sew the liner in, or necessarily make it out of cotton. Cotton will hold moisture - sweat/perspiration/respiration - and if wet, will actually exacerbate the cold.

What is the filling in your bag? Down? Synthetic? I'd hold it up to some bright light, to make sure that the baffles actually contain fill that fills the complete baffle, and is not stuck in the bottom of each (which can happen over some years of use).

I too have my doubts, sir, hence asking around No I have not used it before at -10°C. In fact, it'll be my first winter trek.

@inditramp Oh and berating is what I've come here for. I'm grateful for the verbal berating by a fellow community member than a practical berating by the mountains later . The helpful yet firm way in which you've put this across is, IMHO, how we first timers should be put down before we indulge in something that can hurt us. Sadly, many people get defensive when berated and everyone these days is hell bent on sounding politically correct. But I digress.
And I agree that you are crazy! Who covers all of HP, Nepal, and Zanskar :O You sir, ought to post many trekalogues here.

I agree--the real rating will depend on how susceptible I am to cold and how well any bag can retain heat. Thanks for the tip. My bags have synthetic filling that (still!) completely fills the baffles and thankfully is evenly distributed inside.

Down bags are, right now, too costly for me to afford. Can I offset a few degrees by dressing up in three or four layers and using chemical warmers inside? If not, I shall rent something good from an agency.

At -10C, I'd be in nothing but down. Any additional layers (and you'll need more than a few) will add weight for you. Rent a good down bag, be done with it

Hmm... makes sense considering I am generally susceptible to cold and being cold is just plain irritating for me. (Damn! I should've picked a hobby not involving the hills ) Appreciate your guidance.

How do I recognize if what I am being handed is down? Not that I suspect rental agencies but besides curiosity, I also want to do due diligence on my part.

Many down bags, especially, I imagine, rentals, might have more than a few little bits of down poking out of the bag material. Usually it's the end of the feather that does this. Look for these, if you see one sticking out, (Shhhh . . . ) pull it out , see for yourself
