Thermal Underwear Base Layer Top,black

Very nice for price!

I wasn't expecting much, so was happily surprised by the flattering fit and soft material. A really nice layer for the price. I will wear both as a long sleeved shirt on daily basis in winter and as under layer when hiking or skiing. Size was right on. I usually wear a small or medium in other brands and I ordered a medium and it fits just right.


Very warm and comfortable fit!

Great quality product for cooler climates

I brought this because I went to the Blue Mountains in NSW, I live in QLD Australia, I was thrilled with how cosy warm I was, night and day. Have been washed several times and absolutely no sign of wear and tear. And the purchase price was an absolute bonus. Thank you Decathlon

Additional Product Information


Main fabric: 100.0% Polyester

What is the fit of the 100 base layer?

The 100 base layer comes in a REGULAR fit.It's a classic straight cut suitable for all body shapes.

What are the benefits of polyester?

Polyester is the most-used fiber for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibers can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet.It is limited in its ability to reduce odors.

How to dress to stay warm on the slopes?

You just need 3 layers to keep dry on the ski slopes:- Layer 1 or a 2nd skin, to stay dry. - Layer 2 or an insulating layer, to keep the heat in. - Layer 3 or a protective layer to protect against the elements.

A product-specific environmental rating

The product's environmental footprint is calculated for its entire life using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, pants, backpacks, etc, ...).

Product testing

All Wedze products are created, designed, and developed in the Mont Blanc Valley. They are then tested under the same conditions as you would experience in real-life use (snow, cold, powder snow, etc.). The design teams ensure that the program for which the product has been designed and developed matches perfectly with its use in the field.
