Reddit reviews Daily Life in Medieval Europe

Daily Life in Medieval Europe may be a bit too general for what you are looking for, but it does include a section on clothing and even includes some cloth patterns if you are trying to make your own medieval clothing.

Another book, Fashion in the Middle Ages may be closer to what you are looking for, but again this is much broader than your specific 'winter/cold weather' clothes.

This book Medieval Tailor's Assistant: Making Common Garments 1200-1500 may be your best bet. From a customer review:
>This book covers everything you ever wanted to know about medieval clothing, from measurements, patterns and materials to methods of construction. It has over 400 illustrations of medieval clothing, and 121 patterns for shirts and smocks, cotes, doublets, kirtles, hose, surcotes, cotehardies, gowns, overkirtles, cloaks, children's clothing, headwear, and accessories.


Sorry I couldn't be of much help other than a few Amazon links, but hopefully one of these will at least point you in the right direction.

Edit: oops! Saw someone else recommended Tailor's Assistant already. My apologies, but let us know if you find anything interesting!
