The Ironwood is part of our Outdoor Collection, but what does that mean? It means we created this collection specifically with campers and outdoor enthusiast in mind. As you noticed we don't do things like everybody else so we created our own blend of twisted fibers that keep you cooler, pull moisture away faster, and are 37% more durable than anything in the current market. We combined our signature air channel cushioning, anatomical fit, and performance meshing technologies to bring you our most thoroughly considered collection to date for the outdoorsmen and weekend ramblers who take to the hills as often as they can. Are you ready for adventure? We thought so.
