Product Reviews

Suits my skin, smell nice and feels warm. Can be used as base layer, though expensive. Hope, it will not fillet/corn out at elbow area.
inexpensive merino wool base layer - Great!
Please improve quality. I bought the product to wear during winters in the UK. Although it is made of merino wool and does the job, there is a big hole in one of the sleeves.

No advice yet but for me is great !
Merino wool base layer at less than half the price of Icebreaker. 2 sets (top and bottom) served me very well over 8 days walking around in Tokyo this winter. Good product, highly recommended!
Thank you for taking the time to leave a review for the Mountain Trekking Merino Wool Top. We are glad that this product served you well! Yes I believe our products are not only affordable but it is technical as well. Hope to see you around in our stores soon!
Cheers!

This was again an awesome and value for money purchase. It kept me warm in the chilling, windy, rainy, snowy winter of Europe
Very warm on the bicycle, good cuff for hiding the zip
Used it on a 6 day hike to Pindari glacier, in the Himalayas. Gained altitude of 12,000 feet. Great base layer. Fits perfectly and feels warm when weather is chilly. This is the first base layer I have really enjoyed wearing (have been hiking in synthetic base layers since 2010).

What are our commitments in favour of animal welfare?
We only use wool from Merino sheep bred 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: https://www.forclaz.fr/merinos-2019-bp_4128
How did we improve the durability of our merino wool t-shirts?
We use a BETA-SPUN yarn structure, i.e. the merino wool fibres are coated with a fine sheath of polyamide filaments to protect them from rubbing and cuts, without affecting the properties of the wool.
Odour control
Wool from Merino sheep naturally controls the spread of bacteria that cause bad smells. This Merino wool T-shirt can therefore be wornseveral days in a row and means you can take less clothes when trekking making for a lighter backpack!
Reducing the "freezing effect"
After exercise and heavy sweating, 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.
Advice before use
To make the component feel softer, don't hesitate to wash your T-shirt before first use.
How to wash your merino wool t-shirt
We recommend that you machine wash your Merino wool tee-shirt at 30° 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:https://www.forclaz.fr/conseils/comment-laver-mon-tee-shirt-de-trek-en-laine-merinos-tp_1550
