From mid-week dawn patrols to remote ski expeditions, the Black Diamond UltraLite Mix STS skins are ideal for when efficiency and packability are essential. Built with our mohair-nylon mix and a completely updated construction that makes them 20% lighter and more packable, the UltraLite Mix STS provide the perfect balance of lightweight glide and uphill traction. An innovative Dynex™ and aluminum LT tip loop provides a secure and field-replaceable connection, while our reliable STS tail attachment allows for up to 10 cm of adjustment.
