The reflective material on the inside of these gloves doesn't seem to have an advantage as they are no warmer than similar liners without. I also had a stitch that came undone on one of them after just a month or two. However, they are still in use. I pinned the seam and instead of using it as a lining I slipped it over a pair of knitted gloves to protect it from the wind. At least it wasn't a total loss.
