To choose your size, measure a similar garment that you own, lying flat, then compare with our table.

T-shirts are too often made from cotton. The problem ?
Cotton traps odors, takes hours to dry, and its cultivation uses large amounts of water.
With the Action Merino range, we set out to create a fabric that’s comfortable, lightweight, and breathable, using two high-performance, eco-conscious natural fibers: wool and wood.
What sets this T-shirt apart is its extra-fine merino wool compositiona premium natural fiber.
Learn more about our extra-fine merino wool.
We use an ultra-fine 16.5-micron wool sourced from New Zealand, guaranteed mulesing-free.
The Tencel we use comes from eucalyptus grown in forest ecosystems that require no artificial irrigation, making it far more efficient than cotton.
Its environmentally responsible production process recovers nearly all solvents and recycles water for future production cycles.
Tencel outperforms cotton across the board:
Absorbs and releases moisture more efficiently
Its smooth texture delivers superior softness
Uses significantly less water to produce
Offers better breathability and durability
This jersey is designed to be worn close to the body.
55% Tencel™, 37% 16.5-micron extra-fine merino wool, 8% elastane
160 g/m²
The premium knitting and construction are carried out by our partner workshop in Lithuania.
This fabric was developed exclusively by Seagale. You won’t find it anywhere else.
This fabric feels incredibly soft against the skin, thanks to its blend of ultra-fine merino wool and smooth, silky wood-based fibers.
Our Austrian spinner Schoeller Spinning Group creates a single yarn by twisting merino and Tencel fibers together, forming an intimate blend that brings out the best of both materials.
This merino–Tencel combination creates an optimal climate balance while preserving natural resources, as both wool and wood are renewable and 100% biodegradable.
Our blend of merino wool and Tencel fibers is naturally odor-resistant.
Hang it up overnight and it’ll be fresh again by morning, so you can wear this T-shirt for several days in a row without needing to wash it.
This T-shirt is naturally thermoregulating for year-round wear, thanks to its balanced blend of merino wool and Tencel.
You can wear it as a base layer in cooler weather or on its own in the heat.
It also makes the perfect sleep shirt for a better night’s rest.
This lightweight, comfortable T-shirt feels great directly against the skin.
The stretch moves with you, delivering even more comfort.
Untreated wool tends to felt over time with repeated washing.
We use an EXP (EX-Pollution) anti-felting treatment that helps the wool maintain its like-new structure over time, without releasing chlorine that could harm water systems.
A responsible, durable innovation that meets the highest environmental standards.
The classic fit and clean lines enhance your silhouette. The crew neck and fitted sleeves complete the T-shirt’s timeless, refined look.
It’s the perfect alternative to synthetic tees and traditional cotton T-shirts.
Fair warning: this has been our best-seller since 2015 and it’s seriously addictive.
EXP is the world’s first wool finishing process to meet the strict standards of bluesign and Global Organic Textile Standard, and it also complies with OEKO-TEX Standard 100.
The knitting and construction of this T-shirt are carried out by our partner workshop in Lithuania, certified among the most sustainable in Europe.

"Ce T-shirt ne dure pas dans le temps, après plusieurs lavages il commence à boulocher et le tissu se détend. Je le mettais pour le vélotaff sur un trajet de 30min, en le retirant il s'est déchiré sous le bras. Le support m'a juste confirmé que le tshirt est très fragile avec l'humidité (pourtant je n'y suis pas allé fort). J'en avais acheté plusieurs mais maintenant ils sont peu utilisé !"
"Super t-shirt, très agréable. Il rétréci à peine au première lavage à 30. Petite tendance à plisser, donc repassage si on le veut vraiment nickel au niveaux des manches. Mais c’est un super produit !"
"Doux et léger, très agréable à porter à l’extérieur car l’air passe et à l’intérieur pour cocooner. Je les lave programme laine 30°et séchage à plat. Ils sont comme neufs. J’adore la sensation sur la peau. Le textile allie laine et viscose de bambou. Aucune odeur ne se forme en raison du diamètre des fibres. Je recommande ce T-shirt."
"J'en porte depuis quelques années, au fil du temps, j'ai varié les couleurs, parfois aussi les coupes qui changent. Ils ont été de toutes mes aventures à vélo, par temps chaud et par temps froid. Léger, sèche vite, un peu d'odeur (ce n'est pas non plus du 100% mérinos), idéal pour le sport ou les nuits chaudes. 1 seul défaut, il ne résiste pas aux griffes de mon chat :-D Le fil s'en va très vite et détériore ce chouette tshirt. Du coup peu d'entre eux ont vécu plus de 2 ans."
"Très content de ce t-shirt Seagale de la gamme Action ! Il est très léger, agréable à porter toute la journée. Le traitement anti-odeur fonctionne vraiment bien : même après plusieurs heures, aucune mauvaise odeur ne s'installe. Confortable et pratique au quotidien. Je recommande."
"Extrêmement doux, mais bien plus long que les autres modèles (avec mes 1.81m/68kg le M est trop grand, comme pour le Pure Merino d'ailleurs). Prenez probablement une taille en-dessous de celle habituelle."
"L’avantage du mérinos Action, c’est la déclinaison de couleurs. Il est doux et agréable à porter. Je préfère toutefois le mérinos Performance, plus adapté pour mes randonnées."
"I really like the touch of this t-shirt, feels good on the skin, like silk. Compared to the other seagale t-shirts i tend to sweat more in this one, especially if there is no airflow, like with a backpack. Fortunately the moment it gets a bit of air, evaporates any moisture in minutes."
"Sehr angenehm zu tragen und gute Qualität"
"T shirt très agréable à porter, doux, à la fois chaud et léger…"
