Armada Antimatter 108 Review: A Freeride Ski Built for Speed and Deeper Snow

Introduction

Armada has reshuffled its lineup for the new season, and the Antimatter line is a new brand within the brand. Some skis in the family change completely, others get new construction or new shapes and profiles. The Antimatter 108 falls into the middle camp: it keeps the same shape, profile, mold, and footprint as the Declivity X 108 from previous seasons, but adds a new construction aimed at softer snow compliance and better suspension in broken, churned-up conditions.

The headline here is a ski that stays strong and composed at speed while rewarding confident, active skiers who want to surf and drift through deep snow.

Who the Antimatter 108 Is For

This is not a gentle plaything for soft snow. Testers describe it as an absolute beast that takes more effort to get on edge than anything else in the freeride mid-100s category. It demands speed and attention, and once it is on edge, the power is there, but you have to work to access it.

That puts this ski firmly in the advanced and expert category. Stronger, more active skiers who know what they want out of a ski will love what the Antimatter 108 offers. If you want something easier and more turny for deep snow, there are lighter options better suited to that job.

Construction and Materials

The Antimatter 108 uses a poplar wood core and Armada’s Speed Metal technology: narrower metal laminates tuned specifically to the width and shape of the ski, rather than the articulated titanal banding of the old Declivity X 108. The result is a smoother overall feel that stays composed without losing power or stability, and the new construction adds a bit more compliance in softer snow plus a nice sense of suspension when dealing with crud, chop, and broken snow.

The ski is not light. Our 184cm test pair weighed almost exactly 2,100g per ski. The flex is ample rather than stiff, with a thick underfoot core profile and slightly capped tips and tails for greater mobility.

Shape, Profile, and Turn Feel

The shape is thoroughly modern freeride. There is very minimal camber in the underfoot zone and very long rocker in both the tips and tails that extends well down the ski with consistent curvature. Taper is significant too: the widest part of the ski sits well down the running surface, aligned with where the rocker starts, with a very subtle, mostly straight overall profile.

That straightness stands out most. In the 184cm length, the ski carries a 24-meter turn radius, which allows for greater stability at speed while making it easy to break free from a carved turn and get the ski sideways. Smeary, drifty, and surfy all apply. It can certainly be thrown sideways and used in a more creative format, but it stays strong and planted when you get it up to speed.

On-Snow Performance: Power, Speed, and Crud

This ski deserves to be in softer and deeper snow and ridden fast. Speed is a friend here. It works incredibly well in crud, chop, and broken snow, and the new construction makes for a smoother, more composed ride in those conditions without giving up the power and stability the Declivity X 108 was known for.

Tester feedback matches that picture: one reviewer noted it motors through whatever is in its way, calling it a ski that eats deep, heavy powder and spring slush alive. Both runs in early testing confirmed it requires speed and more effort than most, but rewards you with real power once engaged.

Things to Consider Before Buying

The weight is the first thing to weigh. At roughly 2,100g in the 184, this is a substantial ski, and the long 24-meter radius means it is not the most nimble tool for tight terrain or low-speed cruising. It also has limited all-mountain range; its best days are in deep, soft, and broken snow rather than hardpack laps.

Buying Advice

Buy the Antimatter 108 if you are an advanced or expert skier with the strength and technique to drive a demanding ski, and if your primary use case is fast skiing in deep, heavy, or chopped snow. Skip it if you want a lighter, easier, more playful powder ski that forgives low speeds.

Conclusion

The Armada Antimatter 108 successfully carries forward the spirit of the Declivity X 108 with a refined, smoother construction. It is aggressive, powerful, and unapologetically built for skiers who want to charge through anything. For the right skier, it is exactly the kind of beast that makes deep and broken snow feel effortless.
