So what the heck makes them "Click Wheel compatible?" Glad you asked. The iGlove Multi uses the patent pending Playpoint™ technology on the thumb and forefinger tips, which apparently makes for better Click Wheel contact than your wool mittens. The rest of the glove features silicon printing for enhanced grip and durability.
I like the concept of an iPod-friendly glove, in general, but I'd rather see a glove with a warm, snuggly, waterproof iPod pocket built-in and those fancy fabric iPod controls on top. Now that would be a sweet way to hit the slopes.
