The lightest umbrella is the one you don't need. Is that a saying already? Because if not then it should be… Norse may or may not have had this in mind when developing this hat but whether intentional or not, it helps to make your umbrella obsolete.
The advanced range is a research and development project for the Norse team to feel out new ideas whilst working with some of the industry-leaders in outdoor technology. For this hat they have teamed with a familiar name to all: GORE-TEX®. The company whose slogan is "Guaranteed to keep you dry" doesn't take things lightly; they test every single product that uses their tech, to ensure it upholds the guarantee.
Norse worked in a few extra details like the chin strap, rubber logo and mesh lining to keep the taped seams off your head.
