Build your trad rack right with the Black Diamond Camalot C4 Package. Black Diamond calls these ten cams sizes 0. 3 6 the gold standard of camming units, and for good reason too. Its double axle design gives each cam a fat expansion range for more versatility in different sized cracks, and it makes each cam work passively without adding any weight whatsoever. The C loop continuous cable stem is strong and durable yet nimble and easy to place, and the thumb loop lets you clip in directly to the cam when you're aid climbing. Black Diamond color coded each cam for easy identification, which you'll appreciate when you're looking for your final finger sized cam amongst a plethora of bigger boys on your harness.
