Camalot Z4

Black Diamond continues to lead the charge on innovating camming devices. First there was the original Camalot, which still continues to be regarded as the gold standard of camming devices everywhere, and then they started lightening things up with the C3, X4, and current Ultralight models. Now, the Camalot Z4 replaces the X4 as Black Diamond's most technically advanced camming device specialized for smaller cracks like the splitters in Indian Creek, or even if you're going light and fast in the Bugaboos. Black Diamond designed the Z4 range of Camalots with BD's top trad athletes to ensure everything any climber could ever want in a cam. Finally, climbers can now squeeze a single-stemmed camming device without the stem bending over, and not just that, every different size has the same flex for a consistent performance. The heads are narrower than previous Camalots as well, and they're easier to place and clean in tighter constrictions. Black Diamond sandblasted the lobes for better holding power, and added a new Dynex sling with a unique colorway that's easier to pick out in a rack full of older Camalots.

  • OmniFlex construction ensures uniform flexes across all sizes

Great lightweight cam in certain sizes

These cams are really awesome, everything you could want in a the .3 size and up. Unfortunately the action feels too gummy in the single axle sizes-the trigger pull isn't long enough to feel how closed the lobes are.

Z4 .1

I used to be an alien guy, now the Z4 covers my rack at the micro end. I've got full confidence to go for it above these tiny but well made cams!

Very versatile

I bought these for my first trad rack and I love the flexible stem. They make tricky placements much easier and confidence inspiring than the rigid stem cams I used before. 5 stars for sure.

One of my favorite cams

Z’s are my go to for smaller sizes. I love how they have the flexible stem but are still easy to place. Great piece of gear.

Lightest trad

Great gear. I just bought a rack of ultralights. Went down to Moab to climb some sandstone. Had a great trip, climbed and biked. Perfect trad rack.

The standard

Camalots. Used everywhere. They're the standard. Bought a couple extra for an upcoming climb, they always perform.
