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.
Chargement…

T-shirts are too often made from cotton. The problem?
Cotton traps odors, takes hours to dry, and its cultivation uses a lot of water.
With the Evolution range, we set out to create a thicker, fully opaque fabric with a clean, elegant drape, made from our high-performance natural materials.

Our Tencel is sourced from eucalyptus grown in forests that thrive without artificial irrigation, delivering significantly higher yields than cotton.
Its closed-loop production process minimizes environmental impact, with nearly all solvents recovered and water reused in future production cycles.
Tencel™ outperforms cotton in every way:
Faster moisture absorption and evaporation
A smoother texture for enhanced softness
Significantly lower water consumption during production
Excellent breathability and durability

To create a T-shirt that’s both thick and comfortable, we developed a unique double-faced construction.
The outer layer is made from Tencel jersey, a next-generation fabric derived from eucalyptus. Far more eco-friendly than any cotton, it also offers an advantage over wool by being naturally bright white.

The secret behind this T-shirt lies in its extra-fine merino wool composition, setting the standard for natural fibers in terms of performance.
- Controls body temperature
- Provides insulation in both hot and cold conditions
- Prevents odor buildup
- Dries quickly after washing
- Comfortable all day long
- Ultra-soft feel against the skin
Explore the properties of our extra-fine merino wool.
We use 16.5-micron wool, known for its exceptional softness, sourced from New Zealand and guaranteed mulesing-free.

The inner face of the T-shirt is knit with ultra-soft loops of extra-fine merino wool.
This three-dimensional structure minimizes contact points, so it won’t cling to your skin and allows it to breathe more freely.
Merino can then fully do its job, regulating your body temperature for optimal comfort.
And since wool doesn’t retain odors, you can wear this T-shirt for several days before needing to wash it.

In short, we’ve developed an exclusive, premium double-faced fabric.

"Exceptionnel de légèreté et un retombé parfait qui donne un vêtement agréable à porter avec un style passe partout"
"Mon t-shirt préféré de chez Seagale est le Pure Merino, je me suis pris un petit Evolution pour tester car j'avais besoin d'un t-shirt blanc et c'est le seul model qui le propose... Je suis bluffé... le t-shirt tombe parfaitement, la coupe est parfaite comme toujours et je le classe dans mon top 2. Attention, il est plus lourd et plus épais. De mon côté, je le réserve pour l’automne, l’hiver ou certaines soirées fraiches d'été. Gros coup de coeur, j'en ai commandé 3 de plus et je pense devoir en commander d'autres pour être tranquille pour cet hiver."
"I have multiple pairs and they all fit really well on my body, they feel good in any kind of water, are comfortable enough to leave on in doors, and are really good at not holding smells."
"Très doux, il est également plus épais que le performance Mérinos et a un plus bel aspect. Très agréable à porter. J'adore."
"Tee-shirt très bien coupé, assez épais donc parfait pour la mi-saison. Le blanc ne ternir pas malgré les lavages."
"My favourite of the seagale t-shirt lineup as of yet. The thickness and weight of the t-shirt is excellent, gives a nice structure to it, no wrinkles. I was surprised how well it regulates the temperature, cool on a hot day and warm on a cold night. Absolutely love it!"
"Mon nouveau favoris, le basique parfait bien épais et doux. La coupe est top. Même Eric m’a dit « il est chouette ton t-shirt »."
"Très beau t-shirt bien coupé (M pour 1. 74m et 78 kg), un peu epais ce qui donne un beau drapé avec une belle matière. Personnellement je préfère le action ou le évolution pour la période estivale. Attention, le blanc est bien annoncé Ivoire donc ne vous attendez pas à un balance éclatant. Le modèle avec le logo est vraiment blanc lui."
"Depuis bien longtemps, maintenant les évolutions mérinos T-shirt sont mes T-shirts du quotidien. J’ai plusieurs couleurs et je les mets quasiment tous les jours seul. Point. Négatif, il y a des différences au niveau grammage et sur certaines finitions sur les nouveaux modèles donc moins de continuité. Sinon rien à dire grammage est porté parfait, ils peuvent être utilisé dans toutes les situations et ne sent pas."
"Confortable, blanc opaque, respirant, belle texture… C’est simple je n’achète plus que ça depuis quelques années… 👍"
