How to Layer for Sailing: Base Layers, Fleece and Mid Layers

Layer for sailing in three steps: a base layer next to the skin, a fleece or insulated mid layer for warmth, and a waterproof shell on top. This guide explains the job of each layer, lists example products from Musto, Helly Hansen, Zhik and Rooster, and gives the sizing data you need to order.

Layers at a glance

Layer Job Brands in our range

How do I choose?

Match the layers to the air and water temperature, the wind, and how active you will be. Several thin layers work better than one thick one, because you can add or remove them as conditions change.

What should I wear next to my skin?

A base layer sits under everything else. Choose a close fit that does not restrict you.

Musto M 99 / 39

Frequently asked questions

How many layers should I wear for sailing?

Three is a good starting point: base layer, mid layer and shell. Remove the mid layer when it warms up.

What is the difference between a mid layer and a shell?

A mid layer such as a fleece holds warmth. A shell blocks wind, rain and spray.

Is cotton a good choice for sailing?

Cotton holds water and dries slowly, so a quick-drying base layer is usually more comfortable on the water.

What is a base layer?

A base layer is the thin layer worn next to your skin, under your fleece and shell.

When do I need a softshell?

Choose a softshell on dry, windy days when a waterproof shell would be too warm.

What are insulated jackets for?

They add warmth on cold days and nights, and you wear them under a shell.

How should layers fit?

Close enough to stay warm and move freely, with room so your shell closes over them.

Should I size up for layers?

Rooster recommends one size up for Aquafleece. For other garments, compare your measurements with the brand chart.

Do sizes match between brands?

Not exactly. A medium chest runs from 97 to 103 centimeters across Musto, Helly Hansen, Zhik and Rooster for men and unisex pieces.

Which brand should I pick?

Musto and Helly Hansen cover base layers, fleece and insulated jackets. Zhik and Rooster focus on layers for dinghy sailing.

Can I use the same layers on any boat?

Yes. Layers carry over from dinghies to cruisers, and the shell is what changes with the boat.
