Everything you need to know about cycling jerseys

Say NO to cotton

Although a cotton t-shirt is comfortable, it is not the most suitable piece of clothing for any exercise, cycling included.

With increased physical activity, you sweat and cotton absorbs the sweat like a sponge. The problem is that is stays wet and takes a long time to dry. This is causing not only that you end up with heavy, smelly and sticky cloth stuck to your body, but also that you get overheated as a cotton t-shirt offers zero cooling effect.

On days when it’s a bit chilly or when you are going downhill, this wet cloth gets very cold very quickly, which is just the right recipe for a nasty cold.

What should the right jersey look like?

A jersey is not just a fashion or show-off accessory. Jerseys are made of performance fabrics such as lycra, merino, wool, polyester, spandex or nylon, or a combination of these materials. They are designed to dry fast and evaporate your sweat away from your skin, which not only keeps you dry but also cools your body.

There are many different jerseys to choose from, depending on what type of cyclist you are or want to become.

Road cycling jerseys

Typical features of a road cycling jersey are a full length zip, pockets on the back and optimized cut for riding in aero position. This usually means that the front of the jersey is shorter than the back.

First and foremost, your jersey should fit the right purpose. You won’t use the same jersey for a race as you would use for a social group ride.

Race fit

This kind of jersey is made to be aerodynamic. It fits tightly to the body to reduce the aerodynamic drag and to help the air flow the right way, which increases the speed of the cyclist.

Race jerseys are used for racing, long climbing or for triathlon. Typical features are really tight fit, sleeves elongated almost to the elbow, short front panel, and very light, thin and technical fabrics. For this purpose we recommend a jersey Climber’s 3.0 from the Italian brand Castelli which is exceptionally close-fitting and aerodynamic.

Performance fit

Still quite tight, but not as aerodynamic as the race jersey. The fabric is close to the body, but not as short at the front. Materials are usually a little thicker and more elastic.

These jerseys are perfect for everyday training, social group rides or endurance rides.

Loose fit

Loose fit must have a straight cut. If you don’t feel comfortable in a tight jersey, this is the right choice for you. It is made for leisure cycling and is perfect for those sunny café rides.

Mountain bike jerseys

Aerodynamics doesn’t play such a big role in the case of MTB jerseys. It is true that you can often see cross-country cyclists wear tight jerseys, but this is an exception. MTB jerseys should not restrict your movement, and they are made from tougher materials, as you are more likely to fall.

The cut is similar to a t-shirt but made from technical fabrics, to wick the sweat away and to keep your body dry. They are also loose as you are likely to wear body protection underneath.

If you are planning to cycle in the forest, you might consider long sleeves, which will protect you against branches.

A cycling backpack with all the necessary little things for the journey naturally belongs to a longer ride. So don't forget the ventilation panels. MTB jerseys usually don't have back pockets, because everything fits in the backpack. For example, try the extremely popular MTB jersey Fox Ranger SS or POC MTB Pure LS Jersey which is a long-sleeved alternative.

How to choose the right size?

Be careful with Italian sizing

Choosing the right size can be tricky, as sizing really varies from one manufacturer to another. In general, Italian made jerseys are usually smaller than the European or US ones.

Italian size tables are different, meaning that you will very likely need a size or two bigger than your standard size. It is very important that you measure yourself before ordering online to avoid disappointment and having to return your jersey.

Ideally, you should try the jersey on in a store before buying if you are not familiar with the brand.

Which jersey is the best for summer and which for other seasons?

In summer go for short sleeves and light sweat-wicking materials. Choose from our wide range of short-sleeved jerseys.

During spring and autumn focus on short-sleeved bike jerseys, which you can complement with arm sleeves. When you don't need them, you can put them in your back pocket. Alternatively, try a jersey with long sleeves without thermal fleece. When cycling in the forest, you can take the Edge jersey from Northwave, for example.

If you cycle a lot or if you plan to cycle a lot, a must-have is Gabba by Castelli – Gore-Tex® Jersey with short sleeves. A waterproof yet breathable jersey, ideal for rainy days. Don't forget to pack a windbreaker and/or gilet in your back pockets.

When cycling in winter it is extremely important to know under what conditions and in what temperatures you will ride your bike. At temperatures up to 15 °C, a winter cycling jersey with thermal fleece is sufficient, for example Pro Thermal Mid Jersey by Castelli. In combination with a windproof or waterproof jacket or gilet, it is more or less guaranteed that you will neither be cold nor too warm. We especially recommend the waterproof jacket Castelli Emergency 2 Rain and the windproof gilet Pro Thermal by POC brand. Both can be folded very easily into the back pocket of your winter jersey and fulfil their purpose perfectly.

However, if you want to cycle in any condition, it is worth investing in a winter jacket.

What features should a road cycling jersey have?

Front zip

Full length zip is a must. This is not just to put the jersey on and take it off easily, but mainly to regulate your body temperature.

When you are really hot and sweating, for example when climbing up a hill, you want to be able to unzip your jersey for better cooling effect. Once you have climbed that hill and are ready to descend, zip it up to protect your chest from cold air.

Premium jerseys have a “zip garage” which is a small piece of fabric that prevents your skin from being irritated by the zip. Also look for Camlock® zip, which allows you to fix the zip in a certain position and doesn’t let it slide up or down.

Back pockets

Usually you will find three back pockets on a jersey. These are very useful for things such as phone, keys, snacks, money, but also for foldable jackets, gilets or warmers.

Visibility

It is a good idea to wear bright colours so you will be seen well from a distance. However, if you are a fan of darker colours, make sure your jersey has reflective features, so you will be well visible in the dark.

Silicone grippers

Popular features are silicone bottom grippers which keep the jersey in place and don’t allow it to slide up. It may happen that the silicone grippers on the hems of the sleeves sometimes irritate the skin.

If you have broad shoulders, pick loose sleeves.

Take a look at sets

However, the jersey alone will definitely not be enough for you. Cycling equipment includes the whole set, which can consist of trousers with cycling liner, gloves, socks or caps.

Choose from our website and combine, whether by design, budget or brand. We don't recommend focusing strictly on one brand, but be sure to buy what fits you best and makes you feel comfortable.

Try, for example, cycling sets - a combination of a jersey Castelli A Tutta Bordeaux and trousers Agu Essential Bibshort II Men with socks POC Seize Short Sock Garnet Red.
