A breathable, waterproof, wool hat? It exists with the Dale of Norway Glittertind Hat. “Ideal for drizzly conditions—moisture beads immediately,” our tester announced after a 12-day trip in the Coastal Range of Southeast Alaska. The head-smacking solution: proprietary DWR, which makes us wonder why all of our hats aren’t waterproof. Note: This beanie runs snug, so it fit under every helmet we tried and kind of looks like a swim cap on its own.
