Review on River Polypropylene Glove Liner Medium: Ultimate Comfort and Protection by Corey Burgess

Bought to replace a pair of silk linings that were unnecessary. They are slightly thicker than silk gloves but can still easily be worn under a heavier winter glove/mitten. Not only are they a little warmer, it seems like they should hold up to normal wear and tear a lot better. The only criticism is the deduction of one star. I usually wear large ones in most gloves (my hand is 8.5" in diameter) so I bought these. I had to order Wednesday as the gloves are a bit long in the fingers. Judging by the price, I'll probably be ordering another pair soon. Update (11/18/14): Had to buy another pair thanks to my dogs. This time I bought a medium and they fit much better. I've used them at up to 80km/h on a 30 degree day under heavy duty leather motorcycling gloves and they seem to help a little, I would advise 5-10 degrees more. These are definitely liners as they are made from woven single layer polypropylene and do not inherently stop the wind much. Maybe good for running or hiking in over 50 degrees to take away the chills.
