Why this T-shirt?

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.

High-performance merino wool

What sets this T-shirt apart is its extra-fine merino wool compositiona premium natural fiber.

Efficient body temperature regulation
Insulating protection in both cold and warm conditions
Natural odor resistance
Fast drying for everyday ease
Softness and comfort
An unmatched soft feel

Learn more about our extra-fine merino wool.

We use an ultra-fine 16.5-micron wool sourced from New Zealand, guaranteed mulesing-free.

Eco-friendly Tencel

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.

Learn more about Tencel.

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

The best of both worlds

An exclusive blend of merino wool and Tencel

What sets us apart: a unique technical fabric

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.

Ultra-soft

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.

Odor-resistant

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.

Regulates body temperature

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.

Lightweight and comfortable

This lightweight, comfortable T-shirt feels great directly against the skin.

The stretch moves with you, delivering even more comfort.

Eco-friendly

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.

Highly versatile

Designed for all your adventures

Your go-to T-shirt

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.

Sustainably designed

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.

Reviews

Bon t shirt, le tencel

"Bon t shirt, le tencel donne cette sensation de fraicheur qui est un plus pour l'été ! Sur le site internet il est dit : résistance 4 étoile, mais la réalité est plutot 2/5, en effet le tissu est très fragile, donc à manier avec précaution (j'ai déjà des éfiloches juste en ayant légèrement frotté contre une surface rugueuse). je recommande sans souci, et la marque Seagale est gage de qualité, tant sur la matière première que le lieu de fabrication. Et les couleurs sont justes sublimes !"

— Gérôme L. (4/5)

J’ai acheté deux de ces

"J’ai acheté deux de ces tee-shirts pour remplacer ceux que j’utilisais habituellement pour dormir, et je ne suis pas déçu. La matière est extrêmement agréable à porter, on l’oublie presque, tant il est léger et confortable. Il ne retient pas les mauvaises odeurs, ce qui est un vrai plus. Bref, une excellente surprise. J’en commanderai certainement d’autres pour le même usage."

— Jérôme M. (5/5)

Action Merino : mon t-shirt référence depuis 2019

"J’utilise le t-shirt Action Merino de Seagale depuis 2019 et j’en suis toujours aussi satisfait. La coupe taille parfaitement, le confort est excellent au quotidien et la qualité est vraiment au rendez-vous même après plusieurs années d’utilisation. Les couleurs sont également très réussies et tiennent bien dans le temps. C’est clairement un des meilleurs t-shirts que j’ai pu avoir : polyvalent, agréable à porter et durable."

— Mathieu G. (5/5)

Comme d'habitude, tee-shirt très agréable

"Comme d'habitude, tee-shirt très agréable à porter : léger, bien coupé, la matière et les couleurs rendent très bien. Attention aux tailles cependant : je commande des tee-shirt et des polos depuis 2022, toujours en taille M, mais pour avoir les mêmes mesures je suis passé à la taille S. Regardez-bien le tableau des tailles pour être sûrs ! Sinon le retour est toujours au top, rapide et efficace !"

— Fabien D. (5/5)

Comfortable, light weight, and cool.

"Comfortable, light weight, and cool. It bought it right before a work trip during a hot week and it was just what I needed. It's super light and packed down small in my suitcase, but kept me comfortable and didn't pick up a bunch of body odor after hours in a hot office. I'll definitely be getting more of them."

— Wylan W. (5/5)

Un confort indescriptible et plus

"Un confort indescriptible et plus jamais une seule odeur de sueur sur mes t-shirts. C’est clair, je ne porte plus mes t-shirts en coton et j’en suis à ma troisième commande chez vous…. toute la gamme est vrai agréable !"

— Sébastien S. (5/5)

Le produit a avoir

"J’en possède plusieurs de différentes couleurs c’est le t shirt à avoir, notamment quand on commence l’expérience Seagale. Bon produit pour le quotidien et les sorties. Confort tenue et durabilité suite au lavage. 👍"

— Florian (5/5)

Ivoire is the new white !

"Fan de la matière. Parfait par ces fortes chaleurs. . zéro problème de couture de mon côté et pourtant certains sont très vieux. . mais de mon côté, je ne fais pas de sport avec (ou très exceptionnellement). Ce sont juste mes basiques de tous les jours et pour ça, ils sont juste parfaits. Il n'y a pas mieux."

— Lionel J. (5/5)

Cela fait plusieurs fois que

"Cela fait plusieurs fois que j’achète des vêtements chez SEAGALE et je suis réellement ravi d’absolument tous mes achats"

Positives: It does not feel

"Positives: It does not feel as good as some 100% merino T-shirts, but it is pleasant to the touch, and its durability is greatly improved, with little pilling despite my using it without restrictions and in situations I would not risk a 100% merino T-shirt. Negatives: The price is a little high considering that it's only 52% merino wool and 48% Nylon. The 6. 6 Nylon is more expensive than regular nylon, but probably much cheaper than merino wool. For me, size M is the better fit, but the armholes are a bit tight. In the L, they are perfect, but the fit is not as good for me. If not for the fit issue, I would give it a five-star review."
