Warm Skin

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.

Great value

inexpensive merino wool base layer - Great!

Not worth the price

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.

Excellent value!

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!

Love this base layer

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).

Product information


Main fabric

  • 14% Polyamide
  • 86% Wool


  • 2% Polyamide
  • 98% Wool

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:

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:
