UNION

Easy out of the hole yet rolls aggressively onto edge, the Union is the rare shape on the water that boasts its seeming split personality. By maintaining a performance-oriented active wet surface, while adding surface area outside of the tunnel, the Union is quick to find plane and easy to find an edge. Slow the boat, and let it rip.

When it’s time to slow the boat down a few more miles per hour, it’s time to bring out the Union. Following our linear design approach, we take our Vapor shape and add four tenths of an inch of surface area. There’s no point in an easy deepwater start if you can’t aggressively roll the ski on edge and rip after you are up. So, like the Senate design, we protect the tunnel configuration by adding the width outside of the concave, between the tunnel and the bevel. This allows the Union to roll, grip and rip like a pro model ski, even at slower speeds. The Union is pure fun on the water, slower speeds, or rougher water, no ski performs better, from easy-up starts to throwing walls.


PRIME FRONT BOOT

The Prime was designed with simplicity in mind. A bungee lace on the upper allows for mobility while the static lace on the lower provides support. It offers great performance and comfort all while being super price conscious.

ARTP
Built to fit any size foot, the ARTP offers the perfect blend of comfort, support and performance.

SHAPE

Union Shape 
The Union follows suit with our design methods by being four tenths of an inch wider than a Vapor. This extra width gives skiers the chance to feel ultimate balance while learning to ski at a higher level. We challenge you to find a ski that is more fun to ride in open water.  

Tip Rocker 
Starting the tip rocker directly at the end of the flat spot gives the ski more fluidity and makes the transition from turning to pulling seamless. More rocker in the tip helps the finish of the turn happen more quickly and with more stability. 

Flat Spot 
The flat spot is your balance point; by making this point right at the toes of your front foot, you get a balanced place to stand at every single turn. This balance allows you to stand with confidence and make symmetrical turns on both sides of the course.  

Straight Lines 
Our unique straight lines allow the ski to be the fastest on the market. The lack of outside radius decreases drag and lets the ski flow with ease from side to side. In turn, you’re getting more cross course speed than any other ski on the market.  

Rocker 
Rocker defines the pivot point on a ski; we’ve moved that contact point closer to the ball of your front foot, which helps the ski pivot easier. The tight radius quick turns are then balanced with our tail rocker which adds support off the buoy, giving you the ability to build more speed from a wider point.  

Edge Angle 
At four tenths of an inch wider than the Vapor the width of the Union creates ultimate stability. This bigger overall profile allows a skier to ski in control without the risk of the ski rolling too far on edge and making them lose their balance.

FEATURES

  • All-Terrain Core – Most forgiving construction.
  • 100% Carbon Fiber - Consistent flex every time.
