MSR retooled its iconic Lightning Ascent, a highly regarded mountaineering snowshoe, to perform better and improve durability. So we tried out a pair in mountain terrain to see for ourselves.
MSR knows snowshoes. It began producing its first iterations in 1995, and its designs have always been unique. In 2004, the brand introduced the mountaineering-focused Lightning Ascent line; its toothy aluminum exoskeleton and steel cross members provided exceptional traction in challenging alpine terrain.
These were the first snowshoes with heel lifts, and they incorporated MSR’s unique modular tails to increase flotation when needed.
The most recent update to the MSR Lightning Ascent released in September 2017. The $300 pair specifically addressed one common complaint: The crampon teeth could bend during use in icy conditions. The brand also claimed improved durability in the frame. I tested a pair during a three-day avalanche safety and rescue course in the North Cascades hosted by Mountain Bureau LLC.
In short: MSR’s updated Lightning Ascent – in men’s and women’s – improve on already impressive snowshoes. The traction, durability, performance, and light weight have made them favorites for those traveling in steep and technical alpine environments. And the improved strength only adds to the desirability of these snowshoes.
MSR Lightning Ascent Traction
A standout characteristic of the MSR Lightning Ascent is the fantastic traction. The entire “360° Traction” 7075-T6 aluminum frame, thicker than previous models, provides edges along its entire circumference and is serrated.
Plus, there are two serrated aluminum cross members, and the hinged crampon has two separate sets of teeth. All these features combine to create traction unrivaled by tubular-framed snowshoes. MSR constructs the new “DTX” crampon out of a thicker, continuous piece of martensite steel with altered tooth geometry. This noticeably improves bending resistance on ice.
I experienced excellent traction during the avalanche safety class. Steep climbs and sidehills on consolidated snow, descents on loosely packed snow, and even icy parking lots – I navigated it all with confidence and never felt traction concerns. Both frame and crampon teeth suffered no structural damage, even after crossing and walking down many rocky creek beds.
