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.

Comfort in the saddle, why we only use the best padding for cycling shorts

Comfort in the saddle, why we only use the best padding for cycling shorts

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.
