These are the warmest and most comfortable mittens you'll find anywhere! They are made with 100% heavy weight alpaca and then lined with a warm and soft boucle fleece. These are the mittens I choose to wear on the mornings when it is -20 degrees in the morning and I have to go out to the barns to do alpaca chores. They are made right here in the USA with fleece from our alpacas and other USA grown alpaca fleece. I highly recommend these wonderful mittens! A size small wil fit most women's hands. A size medium will fit a larger woman's hands.
