21Virages Demarrage Unisex

You only realise how good a base layer is when you are without one. If you are not wearing an undershirt, your cycling jersey gets clammy with sweat and you cool down as soon as you start a descent or come to a standstill. The 21Virages Demarrage long-sleeved base layer prevents this; it wicks moisture away from your skin and keeps your body temperature consistent, even if the intensity of your ride varies.

The base layer is seamless; it has as few seams as possible and these are flat and smoothly follow your movements. This means nothing chafes, not even under the back pockets of your cycling jersey or the waistband of your legwear. The stretchy fabric sits snugly around your body, which is exactly how it is supposed to be: Only a base layer that makes direct contact with the skin can wick away moisture effectively.

The Demarrage base layer has a unisex design and a rounded neck, so it sits neatly under any cycling jersey.

The Demarrage base layer is intended for the colder days of autumn, winter and spring. If you are riding on really cold winter days, take a look at the 21Virages Active Core base layer.

Seamless design

The Demarrage Unisex base layer is knitted with as few seams as possible. Fewer seams mean fewer areas that can chafe, no matter how long your ride.

Thermoregulation

The fabric wicks away sweat quickly and has a thermal effect. It keeps you warm when you cool down and dry when you are working hard, so your body temperature remains stable.

Flat seams

The seams lie flat against your skin and move with you, so you will not feel them under your cycling jersey.

Ideal for:

• Pairing with any cycling jersey, short- or long-sleeved, for road, gravel and mountain biking;
• Men and women – this undershirt is unisex;
• Layering – worn under a windbreaker or winter jacket, it will keep you dry and warm.

Not suitable for:

• Use as a standalone top – it is designed to be worn under a cycling jersey;
• Riders who prefer a loose, baggy fit – the base layer should sit snugly against your body.

Not sure about your size? Here’s how to check:

Measure your chest circumference at the widest point and compare it with the size chart to choose your size. The undershirt should fit snugly without feeling too tight. If you are between two sizes, choose the smaller one; a loose-fitting base layer wicks away moisture less effectively.
