You want a lighter rack for alpine approaches, but most climbing companies assume you mean you want a smaller rack. Camp USA understands, which is why the Photon Carabiner is a lighter full-size carabiner for all your climbing needs. Optimized with a phenomenal strength-to-weight ratio, the Photon keeps the weight down without inhibiting the carabiner's overall strength. It features Camp USA's new SphereLock nose to reduce clutter between the gate and nose.
