Description

Feels light and direct against the skin. The soft, form-fitting fabric follows your movements without chafing, even during longer trail runs or intense training sessions. Ventilating zones help dissipate heat as the pace picks up.

It works particularly well during varying exertion. During climbs, fast sections, and long bursts of effort, you will notice that heat and moisture can escape more easily, while less ventilated zones continue to provide adequate protection. As a result, this base layer is suitable for cool mornings, mountain training, and use under an extra layer.

Provides extra support when you become fatigued. The snug construction around the back helps keep your posture stable during long runs, while maintaining freedom of movement around the shoulders and arms. Choose it if thermoregulation is more important to you than maximum warmth.

Choose this for active use in varying conditions. For easy training in real winter cold, a thicker base layer makes more sense.

Frequently asked questions

Is this a summer shirt or a base layer?

A thin base layer with long sleeves. Wear it under a second layer in winter, or on its own on cool spring and autumn days.

What's the difference with the 3D Thermo Winter Top?

This Ultralight is thin and meant for cool to mild weather. The Winter Top is a midweight merino layer with a half zip for cold days.

Does it help when I get tired?

There's a postural support in the back that supports your shoulders and open running posture, which you notice mostly in the final hours of a long run.
