Wild Country Zeros

The smallest two sizes are designed for aid placements only, and we found them most useful in shallow horizontal cracks where we could view all four cam surfaces. (Because the cams and their expansion range on the tiny units was so small, we found it difficult to see all four cams in vertical cracks.) All six sizes feature cam stops and extendable Dyneema slings, and the #3 through #6 sizes proved to be exceptional free-climbing pieces covering the finger sizes.
Pros: Innovative stem/axle connection produces less leverage than any other cam tested; smallest cams available; cam stops on all sizes. Editors' Choice Award.
Cons: Trigger bars are small.
