Introduced in 1971, this timeless form of pro has retained its relevance as the most versatile, inexpensive protection available to climbers. Their unique hexagonal design allows a Hexentric to fit four different crack configurations. This means that a Hex has a comparable range to a similarly sized camming unit, but is lighter and doesn't cost a king's ransom. Extremely easy to place, a Hex can provide surprisingly reassuring placements in terrain where other camming devices fall short.
