Feather IndexSignature
7.5The MX88 carries the weight of its Double Titanal construction — 1,912g at 174cm places it among the heavier builds in Group 1. That weight is purposeful: the Hollowtech EVO technology extends material reduction into the full shovel area, saving weight where it matters most without compromising the structural integrity of the tip. Austrian craftsmanship and a race-inspired sandwich construction reflect a deliberate engineering philosophy rather than a cost-driven one.
Arrow Efficiency ScoreSignature
9.2The MX88 leads Group 1 in turning radius versatility. With a 14m radius at 160cm extending to 20.5m at 188cm, no other ski in the group offers a comparable range of arc options across its size run. Double Titanal delivers exceptional edge hold on hardpack and groomed terrain, while the Infini Core AMTN — a Poplar/Beech woodcore blend — provides the damping needed to stay composed in chopped and variable snow. The MX88 is equally at home railing tight groomers and exploring off-piste terrain.
Turning Radius Versatility
9.5Radius range of 14m to 20.5m across the size run — the widest spread in Group 1. Short arcs, medium carves, and long-radius GS-style turns are all within reach depending on length selection.
On-Trail Reliability
9.2Double Titanal and Full Sandwich Sidewall construction deliver precise edge hold and stability on groomed and firm snow. The Fast Grip Shovel and Tail geometry enhances contact at turn entry and exit.
Off-Trail Reliability
8.8The Early Rise Technology and Infini Core AMTN woodcore provide sufficient float and maneuverability in variable and off-piste conditions. The 88mm waist limits deep powder performance but handles chopped and backcountry terrain with confidence.
Technical Specifications
Expert Verdict
The Kästle MX88 earns the Group 1 Winner designation for September 2026. No ski in the 88–90mm category matches its turning radius versatility — a 14m to 20.5m range across the size run means the MX88 adapts to the skier rather than demanding the skier adapt to it. Double Titanal and a race-inspired sandwich construction deliver the edge hold and stability that firm-snow and groomed terrain demand, while the Hollowtech EVO shovel and Infini Core AMTN woodcore provide the composure needed when conditions deteriorate. Manufactured in Austria with a construction philosophy rooted in alpine racing heritage, the MX88 is the most complete all-mountain carver in Group 1.
