I'm considering trying (read: attempt) to design a pair of riding gloves for cold-weather riding. Not quite fashionable, but that's not a priority in my book. They would be based on these old pilot mittens. I tried on a pair this morning when the security guard told me I'm nuts for riding in 34 degree (and windy) temps. He picked these up 20 years ago and still uses them. I likey. But they need fingers.
