    Highlights: flexible stem, small sizes

    The Camalot™ Z4 is a revolutionary single-stem cam designed for trad climbers seeking unparalleled reliability and performance. With its innovative RigidFlex stem technology, this cam provides exceptional rigidity in-hand while allowing for flexible placements, ensuring secure holds in a variety of climbing scenarios. 1. Patented RigidFlex stem technology allows for a rigid feel when retracted and flexible placement once deployed. 2. Independently floating trigger wires prevent bending under tension, ensuring consistent performance. 3. Dual twisted cable construction in larger sizes provides uniform flex, while single cable construction in smaller sizes minimizes trigger profile and avoids buckling. 4. Four lobes with a sandblasted finish enhance holding power compared to previous models. 5. Available in sizes ranging from #0 to .75, catering to a wide range of climbing needs, including the smallest cam ever made. 6. Similar head-width to the Camalot C3 design for compatibility with existing gear. 7. Ideal for both crack climbing in the desert and fast-and-light ascents in the Bugs. The Camalot™ Z4 is ideal for trad climbing enthusiasts looking for reliable protection in varied environments. It excels in rocky terrains, particularly in crack systems, where secure placements are crucial. This cam is suited for climbers of all skill levels, from intermediate to advanced, and is perfect for scenarios that demand quick, dependable gear, such as multi-pitch ascents or alpine climbs. Its versatility makes it a must-have for both seasonal and year-round climbing adventures.

    This product is for…

    Trad climbers who want small cams (sizes 0–0.75) that fit shallow, narrow, or horizontal placements where a standard C4 won't go. Hosts consistently recommend them as a second set on a double rack in finger-sized pieces, sizes 0.3–0.75.

    Worth noting…

    Only available in sizes 0–0.75, so C4s are still needed for larger sizes. One host flags trigger wire durability as something to be mindful of, advising against frequent falls on small gear.
