This new binding is geared toward backcountry enthusiasts who look to shed as much bulk as possible on the skin track. With a weight of 490 grams per pair, the Alpinist is Marker’s lightest touring binding to date. The Alpinist’s heel offers both a fixed upward release and an adjustable lateral release with a 15 mm range of modification. The toe springs are pre-set to release at a lower setting than the heel, making the heel the catalyst for determining release, boosting the safety factor. In tour mode, the binding offers zero, five and nine degree climbing aid positions. As for the downhill performance, a 38 mm wide mounting plate provides excellent power transmission and a strong, solid feel.
