Kind of thin sleeping bag to put in bed. The body stays warm all night (even in cold sheets!)
I recommend it to those who are as timid as I am.

Does exactly what it is supposed to do: it keeps you extra warm in cold days and works sametime as a liner. Pictures and measurements are accurate, shipping has been fast. 👍

The item matches the description, the fleece is quite light, very soft, and works great when used with a sleeping bag or on its own in mild temperatures. The zippers are okay and work well.

Product arrived on time and well packaged. Yet to test the fleece bag. Zips appear to be of good quality, and it is a good size. Was nice to receive the carry bag. It is a good size and comfortably fits the fleece bag. The carry bag it is very thin and the zips may not last long. Otherwise good value and quality. I recommend this product ab.
