All measurements given are taken with the garment lying flat, not the body.
The values therefore generally correspond to half of the full circumference (for example, bust or waist width).
To choose your size, measure a similar garment that you own, lying flat, then compare with our table.

Why this T-shirt?
T-shirts are too often made of cotton. The problem?
Cotton retains odors, takes hours to dry, and uses a lot of water to grow.
With the Action Merino range, we wanted to create a comfortable, light and breathable material made with two high-performance and eco-responsible natural fibers: wool and wood.

High-performance merino wool
The special feature of this T-shirt is its composition in extrafine merino wool: a natural fiber of excellence.
Effective control of body temperature
Insulating protection against cold and heat
Anti-odor properties
Fast drying for convenient use
Softness and comfort
Unparalleled feeling of softness
Learn more about our Extra Fine Merino Wool.
We choose an extremely fine 16.5 micron wool, sourced from New Zealand and respectful of sheep (mulesing-free).

Eco-responsible Tencel
The Tencel we use comes from Eucalyptus trees growing in forest ecosystems free from synthetic irrigation, with high efficiency compared to cotton.
The environmentally friendly manufacturing process almost entirely reuses the solvent and recycles the water for subsequent production cycles.
For more details on Tencel.
Tencel beats cotton in every category:
Absorbs and releases moisture more efficiently
Its smooth texture offers superior softness
Uses much less water in its manufacture
Provides better breathability and is more durable

Our difference: a unique technical material
This jersey is perfect to wear close to the body.
55% Tencel - 37% Extrafine Merino Wool 16.5 microns - 8% Elastane
160g/m²
The high-end knitting and manufacturing of the T-shirt is carried out by our partner workshop in Lithuania.
This material was developed exclusively by Seagale: you won't find it anywhere else.

Ultra-soft
This material caresses your skin thanks to its blend of soft extra-fine wool and cool, silky wood.
Our spinner Schoeller in Austria creates a yarn from wool and Tencel fibers by twisting the fibers into a single yarn, an intimate blend of these two materials to bring together the best of both worlds.
The material blend of merino and Tencel creates an optimal climate balance and protects the planet's resources, as wood and wool are renewable and 100% biodegradable raw materials.

Anti-odor
Our blend of merino wool and Tencel fibers naturally does not retain odors.
Air it out overnight and you'll find it fresh the next day: you can wear this T-shirt for several days in a row without needing to wash it.

Regulates body temperature
This T-shirt is naturally thermoregulating for 4-season wear thanks to its clever blend of merino wool and Tencel
You can therefore wear it as a first layer when it is cool, or on its own in very hot weather.
It is therefore also the ideal pajamas for better sleep.

Light and comfortable
This fine and comfortable T-shirt is a real pleasure to wear next to your skin.
The stretch accompanies all your movements for even more comfort.

Eco-friendly
Wool without special treatment tends to felt with washing.
We use an anti-felting treatment called EXP (for EX-Pollution), which allows the wool to retain its structure as new over time, without releasing chlorine which could damage the water cycle.
A responsible, sustainable innovation that meets ecological challenges and the strictest standards.

Your favorite T-shirt
The classic cut and clean lines flatter your figure. The crew neck and patch sleeves complete the T-shirt's elegant and timeless look.
It's the perfect alternative to synthetic T-shirts and classic cotton T-shirts.
We want to warn you: this T-shirt has been our bestseller since 2015 and it is highly addictive.

Sustainable design label
EXP is the world's first wool finishing process to meet the strict criteria of the "Bluesign®" and "Global Organic Textile (GOTS)" standards, and it also complies with the "Okeo-Tex standard 100".
The knitting and production of the T-shirt is carried out by our partner workshop in Lithuania, certified as one of the most sustainable in Europe.
