S3 Cycling Jacket

First of all, you have to understand that no matter how waterproof a cycling rain jacket is, you will get wet, because condensation forms underneath. So the single most important function of a cycling rain jacket is of course to find the right balance between being completely waterproof and at the same time breathable, so the body can get rid of heat and you do not overheat.

S1 Rain Jacket: A less race-fit jacket, more loose-fitting and easy to pack into a back pocket. The fabric is a little more "stiff" than the two other jackets, TEMPO! Pro and S3. For that reason there are mesh sections at the sides that provide both some stretch and let the body breathe. This is a really good jacket for the recreational rider and excellent for commuting.

TEMPO! Pro Cycling Jacket: The perfect cycling jacket, usable for an endless number of purposes. It is completely aero and close-fitting and super elastic, so it shapes itself to the body. It sits tight - and it is meant to. It protects against wind and water and keeps you warm for as long as you keep moving. If you stand still and have become cold, it will not work until the body generates heat again. It is excellent for cold mornings, or to carry in your back pocket on days when you expect rain. You can use it as a "transitional jacket" with a Merino Base Layer underneath, all the way down to 5-7 degrees, so it is also a jacket you can use on the cold days.

S3 Cycling Jacket should have been called Winter Jacket. Because that is what it is. A super comfortable jacket that keeps you warm and comfortable in almost any winter condition and will let you stay warm across a temperature range from minus 5 degrees to plus 5 degrees. The perfect set-up is to use a C3 Merino LS as base layer - and yes, you read that right. You do not need more clothing for winter rides.

Note that the jacket must fit tight and close.

Because S3 combines wind protection, water-repellent properties and insulating fleece with an elastic construction. It protects the body in cold weather, while the side panels help with ventilation and freedom of movement while cycling.

Yes. S3 has three functional back pockets. The elastic fabric keeps the contents close to the body, while the stretchy pocket openings help hold them in place while cycling.

S3 is developed for winter temperatures around -5 to +10 °C. That depends on your training intensity, the wind, and what you wear underneath. With a suitable base layer you can adapt the comfort to the conditions.

It has a water-repellent 3-layer membrane construction. The Vagotex reference documents at least 10,000 mm water column pressure in the fabric. That is a strong material property, while the jacket's overall protection also depends on seams and construction. For prolonged heavy rain a dedicated rain jacket is the obvious choice.

S3 combines insulation with breathable, elastic side panels that help the body release heat. You can also adjust the ventilation with the zip. At very high intensity a lighter jacket may be more suitable.

Because the jacket is developed for the cycling position. The extra back length gives better coverage when you sit leaning forward and helps protect against spray from the rear wheel. Silicone grip keeps the hem in place.

Yes. Breathability is documented at Ret <= 18 according to ISO 11092. That means the fabric allows the transport of water vapour. The full-length zip can also be opened for extra ventilation.

S3 has a regular fit and is developed as a unisex model. The elastic construction follows the movements of the upper body and leaves room for layers under the jacket. We recommend starting with your normal size and trying it in the cycling position.

The fabric has an air permeability of no more than 5 mm/second. That documents a very dense construction, which limits the passage of wind through the material and thereby helps retain warmth.

The fabric is tested to at least 20,000 cycles in an abrasion test at 9 kPa. It also achieves 4/5 in pilling tests after 7,000 cycles. That documents resistance to friction and fibre knots.

For cycling, S3 offers a range of targeted features: a longer back, movement-friendly fabrics, back pockets, silicone grip and ventilation through the side panels. It is a complete construction developed for the body's position and load on the bike.

The jacket has reflective details placed in several places on the body, which increase visibility when light hits them. The orange colour adds an extra visible look in daylight. Always use bike lights and other relevant safety equipment.

S3 is developed in Denmark and produced in the EU with Italian fabric. OEKO-TEX(R) STANDARD 100 documents that all components are tested for harmful substances, while the STeP-certified sewing facility supports documented production conditions.

You are paying for a specialised 3-layer membrane construction, insulating fleece, elastic side panels, a well-considered cycling fit, YKK zip, reflectors and European production. It is the combination of features, material quality and product development that creates the value.

Because we believe a winter cycling jacket has to do more than just keep the rider warm.

It has to protect against wind and precipitation. It has to handle heat and moisture from the inside. It has to move with the body in the riding position. It has to stand up to repeated winter training. And it has to work as one complete system through many hours in the saddle.

That is the balance the S3 has been developed around.

The protective 3-layer fabric is documented to deliver:

• A minimum 10,000 mm water column according to EN ISO 20811
• Spray test 100
• Max. 5 mm/s air permeability according to EN 9237
• Ret ≤18 m² Pa/W according to ISO 11092
• A minimum of 20,000 Martindale cycles for abrasion resistance
• 4/5 for pilling after 7,000 rotations
• UPF 50+

This means we can document both the protection from the outside and the fabric's ability to handle water vapour from the inside.

The fabric weighs 290 g/m² and combines a stretchy outer layer with 27% elastane, a breathable polyurethane membrane and a soft, insulating polyester backing. This makes it possible to combine weather protection with the freedom of movement the riding position demands.

But the material data is only one part of the story.

The S3 has been developed specifically for winter cycling, with a cycling-specific fit, an extended back, functional back pockets, reflective details and a construction designed to perform at roughly -5 to +10 °C, depending on intensity, wind and layering.

On top of that comes OEKO-TEX® STANDARD 100, which means every component of the product has been tested for harmful substances, as well as production at an OEKO-TEX® STeP – Sustainable Textile Production certified production site.

The fabric is produced in Italy, and the jacket is made in Lithuania.

At the same time, the S3 builds on FUSION's more than two decades of experience with performance sportswear, and on a development model in which lessons from use, production and previous production runs are continuously turned into improvements.

That is why the ambition for the S3 is very simple:

To create the world's best winter cycling jacket for cold, wet and windy conditions.

Not necessarily the warmest jacket.
Not necessarily the jacket with the highest water column.
But the jacket that delivers the strongest overall balance between:

wind protection + water protection + breathability + insulation + freedom of movement + durability + cycling-specific function.

That is the ambition the S3 is built around.

Quote from Christian Moberg, former professional cyclist and current sports director at Coloquick Cycling: In my 30 years in the sport, I have yet to come across a jacket that can handle even the worst days the way the FUSION S3 jacket can. It is both warm and breathable. We have done training rides with the ColoQuick team at minus 15 degrees in the S3 jacket with just a sweatshirt underneath. It has an incredible ability to hold in the heat while getting rid of sweat at the same time.
