Also known as the Dynafit® System or Tech, TLT represents the lightest alpine touring bindings available and requires special boot fittings. SCARPA has 10 boots with TLT fittings, including the Terminator X and Terminator X Pro telemark boots (NTN) that are compatible with touring bindings. SCARPA is the only licensed manufacturer using Dynafit®-made inserts, both standard and “Quick Step-In.”
