Suzanne asked what I wear on my hands to keep them from freezing. Here is a photo of my wind bloc fleece mittens, rain overmitts if needed, and chemical hand warmers for frozen rides ;’-). Mostly I wear the mittens alone but am always prepared with more. I find that mittens work better for me than gloves. The fingers keep each other warmer than if they are separated in gloves.
Wearing the fold back mittens allows freedom to take photos and ease in shifting and maneuvering around the handlebars, and using my phone map app or answering the phone if need be.
