Essentially a mountaineering harness, this year's Challenge is larger, enabling it to be worn over bulky clothing, or for multiple users of varying sizes. The 3SO buckle system is easy to use and doesn't require doubling back. It even includes two gear loops that can be repositioned. The Challenge is also a great choice for gyms and ropes courses because of its bomber construction and easy adjustability. New for 2004, we have added the Dino, a children's version of the Challenge.
