Mountainsmith sleeping bag liner

  • Familiarity: I've used it once or twice and have initial impressions

I have no problem with the liner, however the size stated and represented on the package is not correct. My liner measures 72"x 32" not 78"x 36" as the stuff sack shows. That said I did wash warm water not hot and I did not measure before washing, but there's no way it should have shrunk 4" on the horizontal and 6" on the vertical from a wash. I am 6'2" so when I lay in the liner it only comes up to about the top of my shoulders and tends to creep down a bit during the night. It's comfortable and protects enough of my bag so no worries. Only 4 stars for not being the dimensions as advertised.

Great liner

  • Familiarity: I've used it several times

I love this liner. I have used synthetic liners before and I don't like the feel of them. This one is in pure cotton and feels great. Great value for the price.
