Product Customer Reviews

I bought this in orange. Very slight quality control issues on an inner seam but nothing functional nor a deterrent to this exceptional value. 86% merino long sleeve for $45. I would love to try the short sleeve merino shirts but I really dislike the two-tone color theme Decathlon does with some garments. As we say here in the US, it looks really cheesy.
Bought this for backpacking and quickly found it works well as a layer for cool/cold weather golf as well. Comfortable, great fit and plan on ordering a few more.
Dries super fast too. I washed it in my washing machine on delicate and then hung to dry. It was dry in about an hour I was so surprised!
Hello Stephan!
Thank you for taking the time to write to us about your product experience.
Wishing you a fantastic day :)
Thanks & Regards,

Very cosy comfortable top.
Super, warm, light and cool feeling all in one. Great product, would have liked less branding but this is a small issue for a pair of scissors.
I've used these baselayers when mountain biking. They are easily as good as other makes that cost twice as much. I can't fault them and the fit is as described.
brilliant base layer for the money, I have two now and more to get, the older one has had loads of washes and still in good shape no sign of shrinking. the wool makes it warm and not a sign of BO, so can wear for days when out on adventures,
After one wash the product in question developed a hole in the right shoulder. A poor quality product in my eyes, stay well clear. When I approached decathlon I was told I could get a refund or exchange, only if I come to a store or fill out all paperwork and send back for a refund. Very inconvenient and this has tainted my opinion of Decathlon.
Really good quality top, very warm, fits slightly smaller, washes great.
After using Icebreaker tops and leggings for a few years I was surprised these tops are so well made. I prefer them over my other brands now as they are softer and a better fit and a bargain at around half the price. I'm really impressed with these tops. The two I have are now nearly a year old and have been worn and washed a lot and are looking fine with no signs of wear.
Ok
Good quality and price.

Additional Product Information
Composition
Main fabric: 86.0% Wool, 14.0% Polyamide ; Yoke: 98.0% Wool, 2.0% Polyamide
How have we reinforced the durability of our merino wool t-shirt?
We use a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibers and protect them from rubbing and cuts without affecting their properties.
Odor control
Wool from Merino sheep naturally controls the spread of bacteria that cause bad odors. This Merino wool T-shirt can therefore be wornseveral days in a row and means you can take less clothes when backpacking making for a lighter backpack!
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 quicker.
Tip before use
For a softer feel, wash your T-shirt before first use.
How do i wash my 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 and NEVER tumble dry unless you want it to shrink by 1 or 2 sizes!For more information: https://www.forclaz.fr/conseils/comment-laver-mon-tee-shirt-de-trek-en-laine-merinos-tp_1550
Product testing
In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team, tested this T-shirt for 4 days in the southern French Alps (Lus La Croix Haute). On the agenda, wind, rain, a bit of snow, a bivouac... and a lot of fun! We were then able to make the final modifications and validate it for use for mountain backpacking.
