Questions riders ask
Is this vest legal on a jet ski in my state?
This colourway is Level 50S, approved to Australian Standard AS 4758. Level 50S is accepted on a jet ski on smooth and enclosed water (rivers, lakes, dams and sheltered bays) in every state. Queensland requires Level 50 once you're past smooth water, and Tasmania requires Level 100 or above beyond sheltered water. Rules change by state, so check yours before you launch. Our guide covers each state.
What's the difference between Level 50 and Level 50S?
They float the same. Level 50 comes in high-vis colours, so you're easier to spot, and it's the one Queensland requires past smooth water. Level 50S comes in every other colour and is the ski, wake and tow vest on smooth water in every state. Neither will turn you face-up on its own, so both are for riders who can swim, with help close by.
What size do I need?
Measure around the fullest part of your chest, under your arms, then check your weight against the chart under Find my size. Snug when it's dry is right. It settles in once it's wet, and a loose vest can ride up or slip off when you hit the water. The test: zip it, clip the buckle and lift at the shoulders. If it rides up past your chin, it's too big.
Is this an impact vest?
No. It's a lifejacket, approved to AS 4758 and tested to keep you afloat. An impact vest without an AS 4758 level mark isn't a lifejacket, so it doesn't count where one is required on the ski or behind the boat.
What if the size is wrong?
Swap it or send it back for a refund within 21 days of purchase. Sale items are the exception. Returns and exchanges has the steps.
How do I look after it?
Rinse it in fresh water after every sesh, dry it out of the sun, keep it away from fuel and store it hung up, not crushed under the esky. Check the zip, buckle and foam before you ride, and replace it if it's torn, crushed or badly faded.
