These Primaloft insulated mittens are shaped for the female hand (although there is also a similar men's mitten called the Loft Flex Leather Mitt). The upper is made of a wind and waterproof fabric, while inside is the magic. Soft, sumptuous Primaloft feels and behaves like down, only without the problems associated with getting it wet. It's super warm and light and keeps hands warm down to some pretty low temperatures.
The palms of these mitts are leather which has been waterproofed, meaning they are good and grippy but don't let you down if the snow turns mushy and there's a chance of gloves getting damp. These keep hands dry and warm.
They come in a variety of attractive colours and a broad range of sizes too.
