1 jacket, 3 uses, a whole range of technologies. When the winter months and colder weather is upon us, we need to don some warm clothing if we don’t want to give up on hillside hikes and long dog walks by the reservoir even on rainy days! The first way to wear this type of 3-in-1 jacket is as a waterproof in wet weather. The second way to wear the jacket is to re-move the jacket altogether so just the inner cosy fleece remains, and the third way to wear the jacket for ultimate warmth is to layer up and wear the two zipped together.
