Vest Size Charts

We want you to get the right fitting jacket the first time. Please refer to our size guidelines before ordering your jacket.

**Please note that if your stomach measurement is larger than your chest measurement, use your stomach measurement. Overall fit of a jacket when dry is supposed to be tight. In a neoprene vest you must be able to stretch the vest 2" to 3" to zip it up, if the zipper meets together without having to stretch the vest is too big.

How to pick the right wakeboard?

Wakeboards should be picked according to your level of experienced. Riding a beginner wakeboard is different from experiencing an advanced wakeboard plank.

Rocker curve is one of the roots of the performance definition of a board. Different styles and approaches require different curves. There is no "right" curve that work for everyone. It's all about what feels right for you.

You'll see different boards incorporate varying degrees of these four basic rocker types.

The continuous rocker profile offers a smooth, predictable ride, with flowing transitions into turns. The hybrid rocker profile blends two curves together for improved performance.

The three-stage rocker profile adds a break in the curve for aggressive riding style and a flatter center curve for speed and rail control.

The five-stage rocker profile gives the rider an extra straight-up kick off the wake without the braking effect of a traditional abrupt three-stage bottom curve.

Bigger boards are a great option for slow speed rides and for beginner wakeboarders.

The appropriate board size depends on weight, skill level,
and volume of the board. The more you weigh, and the
lower your skill level, the bigger the board you’ll need.

One liter of volume floats one kg weight.
In order to factor in your skill level, multiply your Skill Level Factor x Your Weight in kilograms to get your recommended volume in liters.
1 Lb. is approximately equal to .45 kg.
When in doubt, lean to the next board size up.

SKILL FACTOR:
Beginners = 2
Intermediate = 1.7
Advanced = 1.3
Calculating Board Volume:
(Your Weight in lbs. X .45) x Skill Factor = Target Volume
Example:You are a beginner and you weigh 195 lbs.
(195 lbs. X .45) x2 (Skill Factor) = 175.5
Your board should have a minimum volume of 175.5 liters.
