3-Layer Trail System: Protection & Breathability

FAQ

Why use a 3-layer system in trail running?

In trail running, conditions can change quickly. The 3-layer system allows you to adjust your outfit in real time by adding or removing a layer depending on the cold, rain, or effort level. This flexibility improves comfort, limits overheating, and helps maintain a steady effort over time.

Is it always necessary to wear all three layers at once?

No. The principle of the 3-layer system is not to pile on clothes systematically, but to choose the right combination at the right time. When running, one or two layers are often enough. The third layer is used when conditions require it, such as in rain, wind, or cold.

Which Raidlight products follow a three-layer system?

At Raidlight, the 3-layer system is based on technical garments designed to work together. The base layer relies on our breathable SEAMLESS shirt, designed to effectively wick away sweat and reduce chafing. The middle layer uses lightweight insulating clothing, such as the WINTERTRAIL, to provide warmth when intensity drops or conditions turn colder. The outer layer consists of windproof or waterproof jackets, like the ULTRALIGHT WINDPROOF or the ULTRALIGHT 3.0 equipped with the MP+® membrane, to protect against wind and rain.

Each piece is designed to remain light, compact, and easy to combine, allowing quick adaptation to conditions without weighing down the gear.
