Herren Ärmelloses Unterziehshirt

The ambient range this piece is built for at a steady riding effort. Wind chill and rain sit outside this measure, so on exposed or wet rides pair it with a shell or an additional layer.

How readily the fabric moves heat and moisture vapour away from the skin. Higher values mean maximum airflow for high-output efforts. Lower values prioritise protection over venting.

The degree of deliberate pressure the garment applies to the muscle beneath. Higher values hold the muscle more firmly for support on longer efforts. Lower values sit closer to a standard next-to-skin fit.

How much of your body heat the piece retains. Higher values suit cold, low-intensity or stop-start riding. Lower values keep you cooler when working hard.

Resistance to rain and road spray, from light shower resistance at the low end to sustained rain protection at the top. Higher water protection generally trades against breathability.

How effectively the fabric blocks wind and the chill it carries. Higher values suit exposed descents and cold headwinds. Lower values allow more airflow.
