World-class construction in our own factory, using the highest quality materials and hand checked Quality Control at every step. The Ozone factory manufactures all our Kites, Wings, Boards, Hydrofoils, Paragliders, Speed Wings and Accessories - the same Quality Control processes are used across all products.


All New Ripstop Material Combination

All New Ripstop Material Combination

The new rip-stop canopy material has an advanced ultra flex coating improving feedback in gustier conditions making for a smoother ride. The new technical rip-stop dacron is super tough, used on the Leading Edge and Struts it improves strength, durability and longevity

Fast Flow One-Pump Inflation System

Fast Flow One-Pump Inflation System

The Fast Flow One-Pump Inflation System makes set up and packing quick and easy. It features single point inflation/deflation and a high air flow rate between the Struts and Leading Edge, with clips to seal the hoses to prevent unwanted air flow in case of damage.

High volume inflate/deflate valve

High volume inflate/deflate valve

A high volume valve makes inflation and deflation quick and easy. Pumping is a breeze thanks to the high airflow rate, while the internal seal engages to stop any air coming out under pressure. Unscrew the bottom of the valve to deflate and pack with ease.

Fool proof line connectors

Fool proof line connectors

Fool proof line connectors prevent incorrect rigging of the flying lines to the kite.

Anti-Snag line deflectors

Anti-Snag line deflectors

The Anti-Snag line deflectors prevent bridles and lines from tangling around the wing tip. Safety is increased when launching with a partner and water re-launch is made easier.

Unique bladder construction

Unique bladder construction

Our bladders are constructed in-house with advanced custom built welding machines. Double layered sections are applied to any potential wear areas.

Direct Connect Struts

Direct Connect Struts

Our Direct Connect construction method improves load distribution between the Leading Edge, Struts and Canopy. Struts are connected directly to the Leading Edge with internal and external reinforcements. This unique construction method ensures clean profiles are maintained with the optimum canopy tension.

Double Stitched Folded Seams

Double Stitched Folded Seams

Sail canopy seams are stitched, folded, and then stitched again for a clean and strong connection of the panels.

Internal reinforcements

Internal reinforcements

What’s on the inside counts too – internal reinforcements for improved strength and durability; such as a Double layered Dacron + Insignia taped Leading Edge closing seam with high strength threads.

Load Distribution Panels

Load Distribution Panels

Dacron reinforcements are used on all loaded areas for enhanced load distribution. This means all loads are spread evenly into the sail ensuring the kite flies and performs at its best.

Low profile aerodynamic Scuff Pads

Low profile aerodynamic Scuff Pads

Leading Edge bumpers are often large and unnecessary cosmetic items. At Ozone we build our kites and wings for performance and durability using the best materials & components available. Any areas requiring scuff protection we use a lightweight durable material with superior abrasion resistance, while keeping a low profile in order to reduce drag and maintain performance.

Reinforced Leading Edge and Struts

Reinforced Leading Edge and Struts

The Leading Edge and Struts are reinforced in high stress areas to ensure the kite canopy remains in shape and performs at its best.

Reinforced Trailing Edge

Reinforced Trailing Edge

Double layer Trailing Edge strip with an internal light weight Dyneema reinforcement – this reduces canopy wear and helps to maintain optimum Trailing Edge tension as designed. The Dyneema line also reduces any potential stretch at the Trailing Edge.

Tuned Bridle Geometry

Tuned Bridle Geometry

We work extensively during our R&D process to develop the size range to feel in tune with each other. Every kite has a unique bridle layout, individually tested and fine-tuned to maximize the feeling and performance.

A clean and simple design, featuring an easy-to-use trim system and our innovative Click-In Loop Quick Release.

Set Up

  • Attach the pump leash to the looped line at the centre of the leading edge.
  • Make sure all one-pump hose clips are open before you start inflating.
  • Inflate using the IN valve.
  • Refer to the recommended inflation pressure located next to the inflate/deflate valve.
  • Do not over inflate above the recommendation.
  • Do not under inflate or it will not perform as designed.
  • Close the top valve cap. Double check the valve is tightened firm and is sealing.
  • Close the protection cover.
  • Close all one-pump hose clips. This isolates each strut from the leading edge, so if you get a puncture in one part of the kite the rest of the kite will remain inflated.
  • Once the kite is fully inflated, turn the kite over and secure the kite using sand or sand bags on either side of the centre strut.
  • Never leave a kite unattended without sand or sand bags on the kite.


Do not ride the kite with the one pump clips undone. If you get a puncture the whole kite will deflate! Always close the one pump clips inside the neoprene covers after pumping up. Do not under inflate the kite or it will not perform to its designed trim and will not relaunch easily.

Attaching The Control Lines

  • With the kite on the sand and leading edge facing upwind start to unwind all the lines from the bar walking downwind.
  • Put your bar in the sand with red side of the bar on the right and start untangling the flying lines, walking upwind towards the kite.
  • We label each line with numbers which correspond to the same numbers on the kite. Use a larks head knot to attach the lines making sure the line label system matches >>  4 to 4; 3 to 3; 2 to 2; 1 to 1. The line labels are on the bar, lines and kite to make rigging stress free and easy.
  • The frontlines have stitched loop ends and the back lines have knots so it is very difficult for you to attach the lines incorrectly.

All line to kite connections are made using a “LARKS HEAD” knot.

Always double check your lines before launching. Wrongly attached lines will stop the kite flying correctly and could therefore mean you have no control of the kite putting yourself in a dangerous situation.


Quick Release Connection

The Quick Release is the primary connection to the kite. Make sure you connect to the Quick Release using the finger as shown in the pictures.

Below the Bar Release (Recommended Mode)

All riders should attach their Kite Leash to the Flag Out System. This is the small eyelet on the Stainless Steel Swivel Ring.
When the release is activated, the kite will flag out and fall to the water/ground.

In all situations make sure that all lines are clear of all working release systems and the kite leash is connected in the right way.

Advanced Riders (Use at your own risk, not recommended) 

Riders performing unhooked tricks or who are more confident and have spent many hours Kiting can attach in Expert mode, where the loop part runs through the large eye of the steel ring. When letting go of the bar in Expert mode (without activating the release e.g. missed handle pass) the kite will depower but WILL NOT flag out.

Be aware in this situation, the Quick Release will be out of reach and can therefore not be released. When hooked in and activating the Quick Release the steel ring automatically slips off and the kite will flag out.

1st Stage of  Release

Activate the Quick Release as shown in the pictures. Providing your leash is attached to the flag out system the kite will 100% depower.

Reloading the Quick Release

Final Stage of Release (in an extreme emergency)

In the case of an extreme emergency where you need to completely release from the kite, use the quick release on the kite leash. This will completely detach the kite and control system from the user, and could therefore hit anything or anyone downwind causing damage, serious injury or death. RIDE RESPONSIBLY.

1st FLY 


Launching and Landing

Instruct your partner on how to handle the kite and agree on a sign together for the release and landing. They should hold the kite in the center of the leading edge at the edge of the window and double check that all lines are clear. It is possible for lines to get wrapped around the tip so make sure they understand that all lines must run clearly from each attachment point.

Before you give the signal to release make sure you are 100% confident that all lines are clear. Then give your pre-agreed signal for your partner to release the kite and gently launch the kite to the top of the window.   

Landing the kite use the same principles >> Most importantly keep your head clear, be smooth and controlled with the kite and land before you are too tired or overpowered.

Make sure you grab the correct side of the bar
– we colour code the bar red for left.

Water Relaunching

Once the kite is face down with the leading edge touching the water:

  1. Pull the bar in towards you to increase back line tension.
  2. Pull one of the rear lines (line attached to bar ends) towards your body with constant tension. Look at the kite as you pull the rear line and be ready to release some tension as the kite flips up onto its tip.
  3. Once on its tip the kite will work its way to the edge of the wind window. This requires some skill and finesse in order to not stall the kite backwards onto the water.
  4. When the kite is at the edge of the window make sure you have the bar pushed at least half de-powered and steer the kite gently to the top of the window.

NOTE: If the kite somehow lands nose down but with the tips facing away, pull one of the rear leader lines to help the kite blow around to the correct position then follow the steps above for getting the kite re-launched.

Self Rescue

If you get in trouble out in the water, there is a simple way to self rescue yourself.

Firstly kill the kite’s power with the flag out system by releasing the chicken loop. The kite will flag out and drop to the water.

Lines are dangerous in this situation so make sure you wind the flag out frontline around the bar at least 10x to disable the kite. Then wrap all the lines together onto the bar as you normally would. You will end up at the kite ideally with the lines wrapped tightly and neatly on the bar. Make a few half hitches to secure the lines.

Once you have got hold of the kite you can drop the bar. When you have reached the kite, take hold of the bridle lines at each wingtip. Hold both bridals to use the kite as a sail to get back to shore safely.

Clamcleat Trimmer

To release the line from the cleat teeth, first pull out and down to unlock the line from the teeth, then set the trimmer line to the desired amount.

Pull the trimmer line down to de-power the kite. This is needed if you are overpowered, for unhooked riding, or if you are walking on the beach or snow.

Release the trimmer line away from you to increase kite power.




Trimming For Line Stretch

All lines should be maintained as close to equal length as possible. Flying lines can stretch over time, generally the front lines stretch more as these take the majority of the load.

To check your lines, unwind the lines from the bar and have a partner hold the lines even at the bar end. Taking hold of the lines at the other end, pull on the lines to check they are even. If the lines are not even you may either;

1) Stretch out the shorter lines. Attach the shorter lines to a car hitch or something very solid. Then take hold of the bar and pull with enough force to stretch the line. Do this to any lines that are shorter and re-check that all 4 lines are equal length.

2) Use the Leader Line trimming knots located underneath the bar ends.


  • Detach the flying lines from the kite, and wrap them around the bar ends in a figure of eight. Use the elastic line retainers to keep them held in place
  • To deflate the kite first release all one pump plastic clips. Then gently open the OUT valve on the leading edge. This large valve dumps the air quickly from the kite.
  • Roll the upwind tip in to the centre. Then roll the opposite side.
  • Screw the inflate/deflate valve in and close the neoprene cover.
  • Fold the kite in 3 sections from trailing edge to fit in bag.

Care & Maintenance

Kites are very technical products and are used in the harsh marine environment. If you use common sense and care for your equipment it will look after you and keep its factory trim for hundreds of hours.

Never pump up your kite on a rough surface which may have sharp objects.

Be very careful with your flying lines. If you catch them on a rock or sharp object thoroughly check each one and we recommend you replace your lines. Also make sure there are no knots in the lines. Knots weaken the line by up to 50%.

Once you have pumped up secure your kite with sand or use sandbags  – Do not use heavy objects or even your board, the fins have been known to rip kites.

Never leave your kite on the beach un-used for long periods of time in the sun and wind. The trailing edge flapping and sand hitting the sail cloth will severely shorten the kite’s life. UV also shortens the lifespan of a kite so pack away when not using your kite.

Never pack away your kite wet, only when 100% dry – This will damage the cloth and its coatings and may lead to dye running. This is not valid for warranty.

Never leave your kite inside your car in direct sunlight.

Always clean your control system with fresh water after every session, and reload/release the Quick Release to check the system is functioning correctly. Store your control system with the Quick Release open. Reload the next time you set up your kite.

When inflating the bladders always inflate slowly and ensure the bladders are inflating correctly in the struts or leading edge. If you see a twist or something looks strange STOP pumping immediately and check bladders. They may need re-inserting to ensure they inflate properly.


We supply a repair kit with the following contents:

1. A4 pieces of sail cloth

2. A4 piece of Dacron

3. 1 x length of 50mm wide sticky black repair tape

4. 6” x 3” Tear-Aid bladder repair patch

5. 2 Alcohol wipes

6. One pump clip / hose / hose retainer

If you have a major repair like a tear across panels, struts or the leading edge take the kite to your local sail repair shop. For minor tears and bladder punctures you can easily fix these yourself with the repair kit supplied with the kite.
