I purchased cheap zippers ($3-5). I do not use invisible zippers. That way, there is more of a gap between the zipper and the material so the fleece doesn't get caught in the zipper. I also use zip ties in the zipper head so I can pull the zipper up and down with mittens on. Luckily I haven't been riding with my club lately. When I used to take the sleeves off on a jacket while riding with the club, it was troublesome to take the mittens off, remove sleeve and put in pocket and put mittens on while keeping up with the group. Now that I have studded tires, fenders and my own customized wardrobe, I'm not sure I would be "welcome" with the group. I know I couldn't keep up.
