How to choose a base layer

Pick the material by how much you move and how long you'll be out.

 

Merino

Merino moves moisture away from your skin, and Woolpower says wool keeps you warm even when damp. Good for cold days and trips of several days.

Honest note: Merino costs more and needs gentler care.

 

Synthetic

Polyester base layers move moisture away from your skin and dry fast. Good for hard, active days, and the cheapest way to start.

Honest note: It dries fast, but on a multi-day trip synthetic usually starts to smell sooner than merino.

 

Mesh

A merino mesh holds warm air next to your skin when you stop and lets moisture out when you move.

Honest note: Mesh only works with a close-fitting layer on top of it.

 

Woolpower weights: Lite is a thin layer for milder weather and high activity, 200 is a terry base layer for cold weather, and Woolpower recommends 400 over a thinner base layer in extreme cold.

Who it's for: Hikers, Defence League members and conscripts, and anyone who spends winter days out in the cold.

What goes over your base layer?

Your base layer is the first layer. Over it goes an insulated mid layer, then an outer layer that keeps out wind and rain. Our layering page shows how the three work together.

Common questions

 

Should I choose merino or synthetic?

If you're out for long days or several days in a row, choose merino: Woolpower says wool keeps you warm even when damp, unlike synthetics and cotton. If you move a lot and want a base layer that dries fast, synthetic works well, and it costs less. Merino costs more and needs gentler care.

 

What do Woolpower Lite, 200 and 400 mean?

They're Woolpower's fabric weights. Lite is a thin rib knit without terry loops. 200 is the classic terry base layer, worn directly against the skin. 400 is a thicker terry that goes over a thinner base layer. For socks Woolpower puts it simply: the higher the number, the thicker and warmer the sock. We carry Woolpower Lite and 200 base layers and Liner and 400 socks.

 

How should a base layer fit?

Close to the body. Aclima recommends something soft that fits snugly next to the skin, and Brynje recommends snug-fitting wool or synthetic garments. Wear a close-fitting layer over mesh. Size charts differ between brands, so check the product page or try them on at our showroom.

 

Do wool socks work in boots?

Yes. Woolpower 400 socks are made to be worn with boots, and Woolpower says wool keeps you warm even when damp. Woolpower recommends boots that are big enough, room to wiggle your toes and laces that aren't too tight. In the cold you can wear a thin sock next to your foot and a thicker one over it. If your boots are tight, choose a thinner sock.

 

How do I wash merino?

Use a wool programme and wool detergent, no fabric softener, and dry it flat. Aclima and Lasting say not to tumble dry. Wash temperatures differ by brand (Lasting 30 °C, Aclima 40 °C), so check the care label. Often an overnight airing is enough.
