The Fenix's all-in-one strap is made from bombproof TPU so it won't soak up water or freeze, and is super easy to slide into via the reclining hiback. Active Strap Tech raises the whole rig automatically when the hiback is reclined, making it even quicker to get locked and loaded. Heelside response is accelerated via our legendary PowerTriangle, created between the high-tensile steel cable, the asymmetric hiback and the base section.
