Every year, we expand the color range of our PASSION and MOTION collections so that everyone can find a shade that suits them. The minimalist PASSION collection and the more visually striking MOTION collection have both found their fans, yet we regularly encounter requests for something bolder, more vibrant — and that is Fearlessly.

We are returning to a collaboration that brings colour, vibrancy, and energy to our clothing. Introducing our new PosterLad art collection, based on the "Purple Glow" graphics by digital artist Vratislav Pecka, aka PosterLad. His signature style is once again unmistakable – colourful minimalism, simple geometric shapes, and compositions that feel lively and harmonious.

Introducing the PosterLad collection, named after its designer. He is a digital artist who has been creating illustrations for more than eight years and has 900 posters to his credit. He describes his style as ‘colourful minimalism’, which is the spirit of this collection. He tries to make a simple visual impression through an interesting combination of colours and composition of individual shapes.

Cyclo-cross, the city of Tábor and the Kalas brand have been inseparable for several decades. In celebration of this, we decided to bring a unique form to this mutual fusion and commissioned a limited edition jersey named “TÁBOR - HOME OF CX”.

Introducing Fearlessly, the bold and original limited edition jersey design created by Lenka, our graphic designer and keen cyclist. It's a design that differs from current trends; a design that wants to be seen. Let's hear from its creator. Meet Lenka.

With the arrival of autumn and winter, cyclists face a period of unstable weather and frequent changes in conditions, which often brings uncertainty when choosing what to wear for riding in colder months. Cold, wind, rain, and snow — this mix of weather moods can easily lead to feeling either too cold or, on the contrary, overheated, which results in excessive sweating and discomfort during the ride. In the following layering tips, we will outline how to dress properly during transitional seasons and ensure the necessary comfort on your rides.

The insert, known among cyclists as the 'chamois’ or ‘pad’, is probably the most important part of any pair of cycling shorts. The quality of the pad is crucial for comfort and performance when cycling. A properly designed pad minimizes pressure on sensitive areas, provides ergonomic support and helps prevent blisters or abrasions. That's why our shorts and tights only feature pads from Elastic Interface, the world-renowned leader in this field. Years of experience, a proactive approach to development and the brand's exquisite materials ensure maximum comfort in the saddle.

We are continuing the tradition of effort to support cycling and will donate all proceeds on Wednesday, 3 December, to youth projects. So, if you buy any product on our eShop on this day, you will also contribute to the support of young Czech talents.

In cooperation with our R&D, we have prepared some basic advice and tips on how to take the best possible care of your cycle wear. How to use, wash and store properly. Please remember that proper product care plays a crucial role in maintaining the performance and comfort of your kit. To ensure your Kalas gear stays in top condition and lasts for many seasons, it's essential to follow these guidelines. However, please don’t forget that these are general recommendations and the most accurate information on how to treat the product can always be found on the label of each garment itself.

When choosing the right cycling gear, proper fit is key. Our customers often have questions about the fit of cycle wear, such as, “How tight should my cycling shorts be?” or “How should I choose the right size for my cycling jersey?” Our advice is that proper fit is essential for both comfort and performance. Your cycle wear should feel snug but not restrictive, allowing freedom of movement while providing compression benefits.

Our goal is to constantly push cycling apparel to the next level so that every rider can enjoy the best possible riding experience. Over the past year, we have focused on improving materials and cuts, resulting in products that offer greater comfort and better performance. Another highlight for the coming season is an expanded size range – a new size 0 has been added to the custom options, ensuring our clothing fits an even wider variety of body types. That’s why we’ve put together an overview of the main updates, key changes, and proven features.

If we want to cycle when the weather is drizzly or rainy, we have two options. Either we hop on the indoor trainer and do a workout from the convenience of our own home, or we step out of our comfort zone and brave the weather outside. Both options offer benefits, but those who venture outdoors should consider a more substantial layer of clothing.

We constantly strive to improve our clothing to meet the high demands of modern cycling while providing maximum comfort. For 2024, we've added off-road FREE RIDE and BMX jerseys to our range, expanded our skinsuits collection and improved some accessories. Here is a comprehensive overview of the main new products for the upcoming season, their main changes and proven features.
