We imagine a world where everyone stays warm, regardless of the conditions. Far fetched? Not really. It all starts with your base layer of clothing. We’ve devoted more than a century to developing products that keep you comfortable from chair lift to campfire.
What’s so important about our base layer? Glad you asked. Base layer is the protective layer you wear closest to your skin. It creates the insulating effect that’s needed to keep you comfortable in the cold.
The ColdPruf Base Layer product line has been developed for comfort and warmth in all cold weather environments, whether at home, on the job or enjoying the outdoors.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
