The Treeline features Atlas's Spring-Loaded(TM) Suspension, a patented design that allows for impact absorption, natural side-to-side flex and deeper crampon penetration for an uncompromised stride. Comfort and security come standard with the Wrapp(TM) MTN binding which utilizes the BOAA(R) Fit System to provide a fast, precision fit with on-the-fly adjustability. The variable forming of the aluminum Reactiv(TM) frame changes from a cylindrical to an elliptical shape to increase strength where the frame bears the greatest load for a stiffer, more responsive snowshoe frame. When coupled with soft, smooth Nytex decking the Reactiv frame provides ample flotation and stability in deeper snow. Hearty, reliable traction is a hallmark of our all-mountain snowshoes and the Treeline is no exception! The forefoot grip of the All-Trac(TM) toe crampon and Advanced Aft Traction provide the necessary grip on varying snow conditions.Size: 25, 30Snowshoe Series: All MountainTerrain: All MountainSnowshoe Category: All Mountain SnowshoesHeel Lift: Yes TechnologyReactiv(TM) Frame: Reactiv-Trac(TM) construction integrates the perimeter aft stability of serrated traction rails with Spring-Loaded(TM) Suspension and the flex of an elliptically formed nose, allowing the binding, crampon, and frame to conform and articulate independently with the terrain.Wrapp(TM) MTN Binding: The Wrapp(TM) MTN binding blends Atlas' proven Wrapp(TM) series design combined with BoaA(R) Closure System crafted for All-Mountain snowshoeing use. Providing a secure fit each and every time, the simple twist of a dial delivers consistent precision when the terrain gets technical.All-Trac(TM) Toe Crampon: The time-tested geometry of our All-Trac(TM) toe crampon provides traction in all directions. Wider traction tabs on the sides and corners complement sharp front and rear points for confident hiking.Stabilock Aft Traction: The weight-activated, StabiLock Rear Traction optimizes weight distribution to its serrated traction elements, for sure footing on the most technical terrain.Spring-Loaded(TM) Suspension: Precision-focused, Spring-Loaded(TM) Suspension's (SLS) patented design, suspends the snowshoe close underfoot so it can move freely with its intended articulation, absorbing impact, flexing naturally side-to-side, and allowing deeper crampon penetration into the slope for a compromised stride.Size ChartSIZELOAD*25"120 - 200 lbs30"150 - 250 lbs35"180 - 300+ lbs*Load = User's Bodyweight + Gear
