A new take on an old design, a classic curved nut with a moderate taper, and a trapezoidal head and grooves and ribs on the main face for a better bite in really featured rock. Lighter and more flexible than many nuts on the market making them very stable and so less likely to pull out from rope drag while you are leading a pitch and very easy to clean. The size run includes seven pieces great for alpine climbing or to complement other nuts you might already have on your rack) at a very reasonable price.
