Cap Type

All of our "FastFlow" bottles use the SureSnap® valve, the best on the market. This valve controls the flow of water effectively and precisely. When you press down, water squirts out of the mouthpiece.
Plus, the anti-leak mouthpiece can stay open while riding without water dripping onto your bike's frame.

SureSnap® valve

The mouthpiece is 100% watertight in closed position. Use this position for mixing the isotonic drink in the bottle or for carrying it in a bag.
Once on your bike, leave it open. The SureSnap® valve prevent leaks. Drink quickly and safely!

How to use the FastFlow valve

There’s nothing worse than a plasticky taste or smell in a water bottle. But this is the case for most cycling water bottles. 
We tested numerous plastics before finding just the right one, which is supple and has a neutral taste and smell. When blind tested against bottles from other leading brands, ours were the most neutral-tasting.

No more plasticky smell or taste.

Clean the water bottle thoroughly after each use. If you use isotonic drinks, rinse all parts of the bottle, cap, and mouthpiece to make sure there is no liquid remaining inside. Use liquid detergent and a long brush to clean the bottom of the bottle. 
Dry well and store with the cap off. Otherwise, mould could develop in the bottle.
Do not put in the dishwasher (particularly above 70°C).

Hood

Our jacket is equipped with a 2-layer membrane. The film applied to the inside of the fabric stops water coming from outside, but also wicks away perspiration. 
This ultra-technical component has a waterproof factor of 10,000 Schmerbers and can thus withstand the pressure exerted by 10,000 mm (400") of water.


Run in the rain without getting soaked!

The breathability of a product is measured by its Thermal Evaporative Resistance (TER).
The lower the resistance (and therefore the coefficient), the more breathable the fabric. Our waterproof jacket also has a breathability index that's lower than 6, so we can affirm it's definitely breathable... And that's just as well, because:why protect yourself from the water outside the jacket only to sweat more inside?

A breathable product for even greater comfort

To allow air to circulate freely, we've equipped this jacket with vents at the upper part of the back.

Discrete and effective ventilation points

The adjustable hood adapts to your body beautifully so that it follows your head movements.

Adjustable hood

Did you know that the intensity of your activity, the height profile, and the weather conditions should influence the choice of your different layers of clothing? 
This is the right order, which can be adjusted according to the parameters mentioned above:
- Layer 1 is breathable and wicks perspiration away to the other layers.
- Layer 2 is insulating, protects you from the cold and keeps you warm.
- Lastly, layer 3 protects you from the wind and/or rain.

stay dry with the 3-layer technique

Nathan, our designer, has left nothing to chance: from the design and choice of colour to the accessories and strategically-placed vents, each detail has been carefully designed and perfected! 
With its subtle and modern lines, and technical and precise finishes, this jacket combines technical quality with simplicity... Perfect for your runs, and much more!
