The Mammut Bionic HMS Carabiner will exceed your expectations no matter what you're climbing, whether it's rock, ice, or a bit of both. I-Beam technology uses a special high-precision hot forging method that keeps this biner surprisingly light, despite its conveniently oversized frame. A Twistlock mechanism makes sure your belay is always locked, and a keylock nose lets you unclip without a hassle. Mammut designed the Bionic with a large arc radius that accommodates any safety device or knot without bulking.
