Leroy's review

I wore the short sleeved merino base layer on a 12 mile back packing walk on the Wold Way. It was a hot day and I was carrying my 33 litre back pack. The base layer wicked moisture away efficiently and I did not feel uncomfortable despite the weight I was carrying.

Possibly the best product Decathlon sell. Just as good as branded stuff twice as expensive. Love the anti odour properties

“Top” value

Merino for this price is excellent

Too delicate

I'm very disappointed with this T shirt as it's already got several runs in the material about 4 inches long. Hardly lasted any time & the material is too delicate for hiking use.


Great tech T-shirt, used for MTBing, walking and climbing. I’ll be getting another few

Stylish and Comfortable

Well fitted top, soft and comfortable and dries really fast after washing.

Great T-shirt (and no pong!)

Bought this for a trek in the Atlas Mountains knowing that there would be at least three days without showering. Comfortable, reasonably quick-drying and it really didn't pong at the end of it all. The only negative was the slightly itchy stitching for the cable on the sleeve. A quick un-pick with my penknife and problem solved. Really impressed, especially at the price.

Great sports shirt

Ideal for bouldering, comfortable and good sweat wicking

Stay cool

I thought I'd try out merino tshirts to see if they do what they say regarding breathability and no smell after a day of cycling in 26 degrees in and around the city. I was kept cool and the shirt wicked the perspiration away..and no smell!! I hung on a line to air for a day and used it again..I will buy more ..good price too considering some companies.

Not odour free

I bought this only because it's meant to be good at minimizing odours, but even after one day's wear, it smells under the armpits.

Great shirt

This shirt keeps me very comfortable when doing outdoor activities in the winter. When doing strenuous activities (e.g. snowshoeing) at a few degrees below zero (Celsius) I am comfortable with only this shirt on my upper body. I'll get more of these for next winter.

Enjoying so far. First merino wool shirt I’ve owned. Will see about durability. Price point seems almost too good to be true but alas the decathlon way.

light weight

light and warm. But it causes itchy on my skin if I wear it for a long day.

Additional Product informations


Main fabric

  • 11% Polyamide
  • 89% Wool


  • 11% Polyamide
  • 89% Wool

Sizing and fit

This T-shirt has a slightly fitted sports cut to help wick away moisture to the outside of the fabric.Select your usual size or one size larger if you prefer a looser fitting T-shirt.


Use of a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibres and protect them from rubbing and cuts without affecting their properties.

Origin of the merino wool

We only use wool from Merino sheep raised on farms in South Africa that do not practise mulesing.We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment.We have full traceability which allows us to guarantee the origin of the wool.More information: visit our website

Odour control

The components used reduce bad odours. Laboratory tested according to the ISO 17299-3 standard.Main fabric: 89% merino woolInserts under the arms: 98% merino wool

Reduction of the freezing effect

After exercise and sweating heavily, Merino wool prevents evaporation helping to maintain body temperature by absorbing the majority of the body's moisture. This therefore reduces any unpleasant chilling effect.Conversely, a synthetic material lets the body temperature go back down again faster.

Tip before use

For a softer feel, wash your t-shirt before first use.

How to wash your merino wool t-shirt?

We recommend that you machine wash your Merino wool T-shirt at 30°C on a normal cycle, preferably with liquid detergent.Dry flat and NEVER tumble dry unless you want it to shrink by one or two sizes!For more information: Visit our website
