Protect your arms from the sun without compromising comfort or performance.

Discover the Castelli UPF 50+ Light 3 arm warmers, designed for cyclists and triathletes who spend long hours training in the sun.

Thanks to their Solare technical fabric, UPF 50+ sun protection, and highly breathable construction, they cover the arms while promoting heat and sweat release.

Lightweight, flexible, and easy to carry, they are a particularly useful accessory for summer rides, long-distance training, and cycling camps in sunny regions.

UPF 50+: high sun protection

When you ride for several hours, the arms are particularly exposed to solar radiation.

The Castelli UPF 50+ Light 3 features a UPF 50+ ultraviolet protection rating.

This rating means that the fabric allows through at most approximately 1/50 of the UV radiation evaluated under test conditions.

It therefore provides high textile protection for properly covered areas.

These arm warmers are particularly useful during long summer rides, gran fondos, and training in intense sun.

They complement the use of a suitable sunscreen on uncovered parts of the body.

Solare fabric: protect without overheating

The distinctive feature of the UPF 50+ Light 3 is its Solare fabric, developed to combine sun protection and breathability.

Unlike traditional thermal arm warmers, their main purpose is not to retain heat.

They allow the arms to be covered while promoting airflow to limit the feeling of overheating during exercise.

This construction is particularly interesting for cyclists looking for UV protection without wearing a long-sleeved jersey.

Excellent moisture management

The fabric of the Castelli UPF 50+ Light 3 uses a polyester base, selected for its moisture management properties.

It promotes the release of sweat to maintain a feeling of comfort while pedaling.

This feature is essential during long rides, when the intensity of the exercise and outdoor temperatures increase.

The arm warmers thus follow the movements without becoming excessively bulky.

Effective hold thanks to silicone

The upper part of the arm warmers is equipped with a silicone elastic.

This finish improves grip on the upper arms and helps limit slipping during exercise.

It keeps the arm warmers properly positioned, whether you are riding on the flats, uphill, or out of the saddle.

The hold is designed to follow the cyclist's natural movements.

Lightweight and easy to carry

The Castelli UPF 50+ Light 3 are designed to be easily carried on your rides.

Their lightweight construction allows them to be stored in a jersey pocket when you no longer need them.

They provide a practical solution for quickly adapting your equipment based on sun exposure and weather conditions.

An alternative to a long-sleeved jersey

Sun protection arm warmers offer great versatility.

Paired with a short-sleeved cycling jersey, they allow the arms to be covered during periods of high exposure.

You can then remove them when you want to return to a lighter outfit.

This modularity is particularly appreciated during long rides and cycling camps.

For what activities should you choose the Castelli UPF 50+ Light 3?

The Castelli UPF 50+ Light 3 arm warmers are particularly suitable for:

• Road cycling in sunny weather.

• Long endurance rides.

• Summer cycling camps.

• Gran fondos.

• Gravel rides.

• IRONMAN preparation training.

• Mountain rides with high sun exposure.

• Cyclists looking for UV protection without wearing a long-sleeved jersey.

UPF 50+ Light 3 arm warmers or thermal arm warmers: which should you choose?

The Castelli UPF 50+ Light 3 prioritize sun protection, lightness, and breathability.

They are intended for cyclists who want to protect their arms from the sun without adding a significant thermal layer.

Classic thermal arm warmers, such as the Nano Flex models, are designed more to retain heat and protect against cool or damp conditions.

The choice therefore depends on your main need: UV protection or thermal insulation.
