The Challenge is a bomber harness that is perfect for groups, ropes courses, gyms and mountaineering.  It's been made larger, enabling it to be worn over bulky clothing or for multiple users of varying sizes.

The Challenge was redesigned in 2007 with a new buckle system that makes it a snap to adjust.  Straps always remain doubled back, and release and adjust very quickly.   It even includes two gear loops that can be repositioned. Although the Challenge features a wide adjustability range, it still comes in two sizes.  CE & UIAA certified.
