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.
A T-shirt designed to take on the longest days, the most unpredictable weather, and the toughest conditions, without ever compromising on comfort or style.
With our Performance range, we combined the softness of merino wool with the strength of Cordura to create the most durable wool T-shirts, quite simply.
And with its long sleeves, it goes even further with you.
An extra-fine 17-micron wool, carefully selected for its exceptional softness and unmatched natural properties.
And because transparency matters just as much, our wool is guaranteed mulesing-free and certified Responsible Wool Standard.
To ensure exceptional durability, we used a premium polyamide: Cordura. This fabric is a well-known textile innovation, recognized for its resistance to abrasion and tearing.
On this T-shirt, we use two types of Cordura:
- A staple fiber (like merino), which can be spun together with wool
- A continuous filament fiber, used to wrap and protect the structure as a whole
It all starts with a tight twist of merino wool and a discontinuous Cordura fiber.
A compact, homogeneous blend that forms a semi-finished yarn far stronger than 100% wool.
This interwoven core is 73% merino wool and 27% Cordura. Already tough. But we go even further.
Around this semi-finished yarn, our spinner Südwolle wraps continuous Cordura filaments using a complex process.
This is what gives the yarn its extreme strength, thanks to its tough outer sheath.
Final composition:
52% extra-fine merino wool – 19% discontinuous Cordura – 29% continuous Cordura filament
Anti-wear, anti-pilling, and anti-fatigue: this high-tech yarn delivers a long-sleeve T-shirt that never gives up.
It keeps its clean look, smooth feel, and flawless structure, even in the most demanding conditions.
Ultra-light yet tough at the same time, it folds into a corner of your bag and fits seamlessly into your everyday life as well as your luggage.
The perfect companion for demanding adventurers.
Merino wool works wonders against odors. Even after several days of wear, this T-shirt stays fresh.
Fewer washes, more freedom.
This technical jersey combines the natural softness and comfort of merino wool with the extreme strength of Cordura.
Performance and comfort, with no compromise at 140 g/m².
Thanks to its hybrid merino and Cordura construction, this long-sleeve T-shirt manages moisture perfectly. It quickly wicks away sweat, dries fast, and delivers exceptional comfort in all conditions.
Merino wool adapts to your body for optimal comfort in any season.
In winter, it’s the ideal base layer, keeping you warm while wicking away moisture.
In summer, it keeps you cool and helps protect you from UV rays.
This long-sleeve T-shirt blends seamlessly into any outfit and adapts to every activity: city life, sports, travel, or downtime.
A clean cut, a technical fabric, and a look ready for anything.

"Grand fan de leur t-shirts et en particulier des manches longues : je les ai presque tous testés! Cette itération tient ses promesses. Super coupe et un tissu technique incroyable. Un peux moins chic que les premium merino tshirts donc le parfait complément. J’en ai pris deux direct."
"T-shirt manche longue de très grande qualité, doux, avec toutes les propriétés du mérinos. Une fois qu’on a testé ça on ne peut plus porter de coton."
"hyper-confortable et solide"
"très satisfait. De plus, depuis 2 ans, je suis. passé de la taille M à la taille S sans effort et sans perdre un seul kilo,"
"Ces t shirts manches longues sont parfait en hiver. Je les mets en 1ere couche sous les chemises et quand je fais de la randonnée ou du ski. Très agréable et doux, très léger, fin parfait à glisser sous la chemise. Je suis juste pas très fan de la couleur, une sorte de vert chiné noir alors que les couleurs gris clair et bleu canard d’avant étaient très belles. J’en avais plusieurs qui dataient de 2021 et je les ai jeté récemment, l’elasthanne ayant complètement lâché. On verra combien de temps il va tenir. J’ai l’impression que les manches sont un peu plus renforcées."
"Particulièrement fin. Sèche très rapidement. Logo à la fois présent et discret 👌"
"Belle coupe droite que permet de gagner en confort et plus intéressant à un usage quotidien. J’aime bien le tissus, que as un belle élégance avec le bleu nuit. Je trouve le cou trop ouvert, m’empêchant de vouloir le porter au bureau, ce qu’aurait été sympathique. Cou cheminée ou plus serré pour la V2?"
"Ce cadeau de noël à mes 3 fils a été apprécié, d’autant qu’ils connaissent la Marque Seagle. Personnellement j’ai été surprise que le sens des mailles partent en travers devant sous le col."
"Un très bon t-shirt manche longue Très bonne régulation de la température: agréable à porter en ballade en ville comme lors des activités plus sportives Et une très belle coupe si vous vous êtes un peu athlétique 🙂"
"Matière agréable à porter, moins absorbant que l'Action Merinos mais j'espère cette fois : autrement plus durable. À voir dans le temps et au fil des lavages donc."
