Biking and birding in winter

[PamNY]

I'm sure all of TE's Wool Weenies would also encourage you to wear wool on your outings. Most of my winter wool cycling base layers have zippers so I can adjust the warmth factor as I toodle along. If I stop somewhere for more than a minute or two I can quickly zip up everything to stay as warm as I can, then unzip as needed when I'm pedaling again. Works like a charm, especially when combined with a good-but-light windproof outer layer.

Thanks for this advice which has worked really well already. True, it's not really cold yet, but I have had two major bird events which were damp and/or chilly and I was totally comfortable because of my zippered wool layers. I admit I was skeptical about wool at first but now I'm sold.

Also thanks for the detailed advice on chemical heat packs.
