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.
