Which jacket should I choose depending on my discipline?


Winter cycling jacket for good weather

I practice recreational cycling

A fan of bike rides, you practice cycling alone, as a couple, with children or during a weekend with friends. You ride to clear your mind and have a good time quite naturally. Jackets with loose cuts, for maximum comfort will be ideal for you!

I practice Vélo Taf

Have you gotten into the habit of cycling to work ? You're right to do so! So you need lightweight , breathable cycling gear that protects you from the rain so you can get through your working day in the best possible conditions.
For cycling to work, equipment such as rain capes , which are very loose and protect you as much as possible from water without hindering your hips and legs when pedaling.
Gaiters can protect your shoes and other safety features can improve your visibility on the road like Castelli's commuter reflex jacket .

I practice gravel

Eager to go out in complete freedom, you need a jacket that is both lightweight so as not to weigh down your bikepack. You also expect your cycling jacket to withstand the vegetation that you will encounter during your outings.

I practice mountain biking

In the woods, vegetation can be tough on your jacket, so you need to make fabric durability a priority! But that's not all, rain, cold, wind are also important factors. And there is no ultimate jacket that will meet all the criteria, which is why you will have to compromise between durability, waterproofing and breathability.

I practice racing cycling

Performance is your only criterion as a cyclist! This translates into the search for comfort and lightness. The jacket that will suit you best is the one that combines breathability, thermal insulation and a cut adjusted to your lying position on the bike to gain aerodynamics.

Choosing the right outfit depending on the conditions?


In order to practice with maximum comfort, you must respect your body and offer it maximum protection. You will wear a first insulating layer

I'm trying to protect myself from the rain

Castelli offers different rain protections with jackets designed to withstand light rain up to the one that is completely waterproof! To protect yourself from the rain , you must differentiate between waterproof jackets and water-repellent jackets .
  • Water repellents will allow water to slide off the fabric so that it can be evacuated while riding. If water stagnates on the forearms or shoulders, it can reach the lower layers and you will be wet.
  • The raincoats are water-repellent but do not let water in, additional protection on the fabric prevents water from seeping in.
There are different levels of waterproofness, which are measured in Schmerbers.
  • From 1300 Schmerbers , the jacket is waterproof. This corresponds to light rain.
  • For moderate rain, choose a jacket of at least 5000 Schmerbers .
  • For heavier rains, there are waterproof jackets with an index of 10,000 Schmerbers or even 20,000 Schmerbers .
The more time you spend in the rain, the higher the protection you need.

I am trying to protect myself from the wind

To protect you from the wind, there are different equipment, vests or jackets, partly incorporating Windstopper technology . The Windstopper fabric developed by GORE-TEX® makes the clothing completely airtight , thus guaranteeing you to stay warm. Indeed, although the membrane offers protection against the wind , it nevertheless allows perspiration to escape. And by facilitating the evacuation of perspiration, the windproof garment will keep your body and other insulating layers dry and therefore warm ! This is why you will be vigilant on 2 indices when choosing your windproof jacket: the MVTR or the RET. The MVTR or MVT rate which indicates the capacity of the fabric to evacuate water (or perspiration in the case of a cyclist). The higher the rate, the more breathable the jacket. So, from 10000 the jacket is breathable, at 20000 the jacket is very breathable and at 30000 the jacket is extremely breathable. The other side of the coin is the balance between breathability and waterproofness. On the one hand the fabric must allow water vapor to escape from the inside to the outside, on the other hand the fabric must prevent rain from seeping in from the outside to the inside!

I am trying to protect myself from the cold

To protect yourself from the cold, you need to take into account the temperature felt on the bike . Indeed, while in running, shorts and long-sleeved t-shirts can be worn almost all year round, on the bike , speed changes the game in terms of feeling . You also need to take into account your practice and your type of outing. Your body will warm up more during an intense outing than during a family ride.

The sleeveless vest

Among professional cyclists , the vest is a must-have !
Very comfortable to wear, it does not hinder the mobility of the shoulders and arms when pedaling. It is a very good alternative to the jacket in mid-season when the days are cool. The vest protects the torso and back from the cold , but when winter is here, it quickly reaches its limits. Castelli offers the perfect vest for men: Castelli Perfetto RoS

I am trying to protect myself from the sun and UV rays

In summer, when the sun is present in the morning and evening to brighten up your outings, you can protect yourself from UV rays thanks to anti-UV fabric. Sun often rhymes with heat. Choosing a short-sleeved jersey and short shorts is essential to practice in good conditions. If you are very sensitive to the sun and UV rays, you can use sunscreen but with sweating, the protection may not be optimal. This is why there are accessories such as sleeves and leg warmers that protect against heat and UV rays.
