The slide thing is interesting, but what's the "4" for??
As you might expect, we end up needing gloves for many games up here, especially after mid October. I started using some diving or scuba gloves last year, and they work like a charm. As long as your hands are moving, it retains most of your body heat and they allow maximum dexterity, making the downs strap easy to handle.
I have used it to -25C (10 to 15 below F?) with success, but it might be too warm for the odd night you guys from Texas might "need" it.
