Whatever winter hiking looks like for you, warmth, comfort, protection, and traction are non-negotiable “must-haves.” So KEEN built an insulated, waterproof, grippy hiker that checks all the boxes. All hike. No compromises. The Circadia Polar has everything you need, and at a good price point, it leaves some money for hot chocolate!

• Better Leather: Environmentally preferred leather upper is lighter on the planet.
