Dakine makes a lot of handwear, and they know what boarders want. Their Targa women's mitten has been around and is newly updated. Mittens are just a good idea as the temperature drops, being a lot warmer for the weight than gloves.
The Targa is a slick, high quality design, with a full leather grip and waterproof Gore-Tex insert. The inside is a soft fleece and the whole mitten is very low profile. The cuff is slim fitting with just a little bit of adjustment via a rip-and-stick tab, and the back of the thumbs are nose-friendly for de-snotting.
The mitt is obviously designed for boarders and others who prefer the high speed, low drag inside-the-sleeve design. The Targa is tough and serves well in double-digits, just be aware the low bulk equals low loft so you may want to go a size up and wear a liner glove for cooler temps. The only other downside is the price; you're clearly paying a premium for style here and getting a light duty mitt at a heavy duty price point.
