Wool Travel Sleep Sack

I've used it several times

Just got back from a Trans-Siberian railway trip. This was probably the best investment I made for the trip! The train stewards gave fresh linens for the sleeper cabins, but this bag was just an added off clean warmth that was easy to use, but not too much warmth. I wish they didn't use snaps as the mechanism to close the side opening, sometimes would roll over onto them under my hip or shoulder, but otherwise, great piece of travel gear - won't travel without it again.

Added those few extra degrees of warmth

I've put it through the wringer

kept me warm when it got a little colder than my bag could handle. Would buy again

Does the job.

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

Hard to write a detailed review about a glorified sheet. It fits my Western bag well, is comfortable, and easy to wash.

You Need a Sleeping Bag Liner

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

I never thought about needing a liner until a friend put it in perspective. It would be like wearing a pair of pants commando style without ever washing them. Our bodies sweat and shed skin cells and other gross things when we sleep, and a liner protects your sleeping bag against that, decreasing the need to wash your bag which greatly wears on the life of it. Simple purchase with big impact.

Does this liner have a zipper to help get in and out of it?
