The standard when it comes to single-stem cams, the Camalot Z4 is Alex Honnold’s favorite cam, and features our patented game-changing RigidFlex stem design, which as the name implies, stays rigid while placing them, yet flexes when you climb past, ensuring easy handling and less walking for a solid placement you can rely on.
to have a single-stem cam that stays rigid in-hand, but flexes once placed. Behold the patented RigidFlex stem. Thanks to the independently floating trigger wires the Camalot Z4 doesn't bend while under tension and retracted, but once placed allows the stem to move, ensuring a placement that stays put and doesn't walk when pulled directionally. The stem on the larger sizes also utilizes dual twisted cable construction which provides uniform flex in all directions, while single cable construction is implemented on smaller sizes to avoid buckling when pulling hard on the trigger and to reduce trigger profile. Featuring a similar head-width as our old Camalot C3 design, but with 4 lobes that are sandblasted for better holding power, the Z4's are not only an upgrade, but are also available in smaller sizes starting from #0, our smallest cam ever made, and ranging to .75, allowing you to dial in the rack, whether you're gunning for a tips crack in the desert, or going light and fast in the Bugs.

"Love this cam. It is lightweight, easy to handle, and the narrow head enables solid placements in shallow cracks where other cams don't work."
"When the Z4's first came out I was skeptical about this new design, but it really does work as advertised. Narrow head fit into places the C4's don't work. The stiff stem with the trigger pulled for ease of placement and floppy when in the rock for being less likely to shift is brilliant engineering! I plan to continue to use these cams and replace them with the same thing as I've done a few times now. - Eric Gunks Guides & Climbing School"
"The Z4s are the best cams on the market, very versatile, easy to place and compliment the C4s very well."
"Lightweight, easy to place, excellent cam."
"Fabulous cam, allows for confidence in the gear, which is crucial for crushing :)"
". 3 through . 5, easily one of the best cams on the market and even competes with totem cams. The . 75 can be a little floppy but more annoyingly the trigger wires tend to wear out fast. Anything . 2 and below (the single axis cams) work fine but the cam action and floppiness is uninspiring. The . 2 size doesn’t seem to fit in nearly as many spots as a black totem. The . 1 and below seem as good or better than other micro cams to me, although the “sponginess” of the action can be annoying"
"Great especially for vertical crack"
"Lightweight, flexy and a low profile cam lobes. Amazing"
"I wouldn't do it on purpose but I've held my partner on a 20' whipper and it's none the worse for wear!"
"Love these cams! They place so smoothly and I feel confident taking a fall on them."
