Warm camisole vest in merino wool

Well made merino base layer, fits well, comfortable and non irritant. Astounding price.

Warm under layer

Merino vest - soft and warm as a base layer. Only available on black but It would be nice to have other colours.

fantastic tank top

I bought one in blue a few years ago and haven't stopped wearing it. I only wish you did some other colours, and I would buy them all.

TECHWOOL women's merino wool base layer camisole

Very nice product, soft fabric, washes well, cold wash, in liquid soap flakes, no softener required. I bought the 'small' & the straps are too loose, I'd buy XS next time. Therefore only wear the top in the garden & not for hill walking as intended.

Tank top

Very good as a sleeveless base layer for warmth.

Excelente camiseta!

Super cómoda y ligera, durable, bonita, calentita. Sólo le bajaría un poco más la sisa y que es un poco costosa, pero de resto, perfecta. Me encanta. Es de esos productos que reconfirman la calidad Decathlon. A1!

Camiseta interior cálida para ambientes fríos.

La camiseta es muy cálida y es también cómoda. Talla ligeramente más ajustada de lo que pensaba, pero en realidad se adapta bien al cuerpo.

Additional Product Information


Main fabric

  • 95% Wool
  • 5% Spandex

Origin of the wool

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing.

Sizing and fit

This tank top has a fitted cut for enhanced moisture transfer to the outside of the fabric. Select your usual size or 1 size larger if you prefer a looser fit.

A score for comparing products' environmental impact

The environmental impact of the product is calculated based on its entire lifecycle and using different indicators. A 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.). Decathlon is committed to displaying the environmental information of its products. Web: Informative video:

How to wash your merino wool t-shirt

We recommend that you machine wash your Merino wool T-shirt at 86°F on a normal cycle, preferably with liquid detergent. Dry flat. NEVER tumble dry unless you want to end up with a Merino T-shirt fit only for a doll! For more information:



Product testing

We've tested the material in a climate-controlled room in order to determine its performance level. The results highlighted the heat-regulation properties of wool. Indeed, after making a physical effort and sweating a lot, wool helps to maintain a consistent body temperature while synthetic fabrics cool down faster. The unpleasant cooling or "freezing effect" is therefore reduced by the Merino wool.

Superior quality. Unbeatable prices.
