If it chatters - it won't bother you in this functional jacket from Schmuddelwedda. Coated jersey on the inside keeps wind and rain out. A high-closing Schmuddelwedda silicone zipper helps you stay dry and warm. This jacket still follows every movement without any heat, because the fully breathable material and the additional air circulation holes under the arms make it perfect to wear. When it gets dark, that's no problem: light-reflecting piping on the zippers makes you clearly visible to others. Keys and cell phones are also safe as all pockets can be closed tightly with strong zippers.
