but it was a bargain...!

I bought a silk sleeping bag liner off ebay from the Scottish Silkworm.
It's a pretty basic bag, sort of tapered a bit to help it fit in a mummy bag, double-stitched down the sides with a bit left unstitched at one side to make it easier to get in and out and a flap for a pillow. It looks well enough made. That's a description, not a review. There's no point me reviewing it until I've used it.
