Why We Like The Black Diamond Camalot C4
Lighter and more convenient than ever before, the Black Diamond Camalot C4 brings the muscle without the heft. Coming in 10% lighter than its predecessor, this iteration saves grams without losing strength and maintains the same camming angle and placement ranges we have come to depend on. Giving the larger sizes stiffer stems, Black Diamond has uniformed flex across the line, so the 6 no longer feels wobblier than the 0.3.

The standard when it comes to cams! Great for all-around trad climbing. Love the new stiffer stem. Feels secure when falling, cam is both sturdy and lightweight

Works like a charm
The C4 is *the* first choice for so many people I know including myself. Its reasonably weighted, priced, and works fantastically.

New C4 feels lighter and smoother
I have not used my new C4 yet on an actual trad climb yet, but in playing with it, it feels very smooth.

I love this protection
It has already saved me twice and it perfectly did its job. I have always recommended BD cams to my friends and colleagues and will continue to do so. Keep up the great work team.

A Staple For A Standard Rack
The C4 Camalots are a great addition to any rack, especially when just getting started with trad climbing. A smooth and consistent trigger action, ability to hold in a variety of rock, and a years of field testing inspires confidence in these cams. My favorite aspect of these over others is that Black Diamond can resling them when the nylon wears out, so you can continue to safely use them for a decade plus! They are not the lightest cams, but unless you are pushing grade or alpine climbing, you won't notice. These are and will continue to be the foundation of my rack.
