Laurent, Outshock product engineer, tells how a T-shirt specially designed for judo came about:
"Often, judokas wear cotton T-shirts. A white T-shirt is required during women's competitions. Men may not necessarily want to be bare chested under their uniform. That's why we created a T-shirt especially for judo. We developed questionnaires for our sport partners, and several judokas wore prototypes during the French championships. We also wanted it to be an affordable product. This product was important to me. We're really proud of it."
A collar designed for judo to prevent irritation!
In judo, you often grab your opponent by the collar. And especially at the start of the season, your skin can get really irritated. To limit friction and irritation, we created a T-shirt with a wide, high collar to wear under your uniform. That way you can give it your all from your very first lesson!
A T-shirt that protects your skin and your uniform!
In addition to protecting your neck from irritation, this T-shirt also keeps your uniform from absorbing perspiration, which can cause it to yellow. To quickly absorb and wick away perspiration, we chose a fabric in elastane and polyester on the sides with several ventilation zones. As for the design, the top of the T-shirt is sleek while the white and grey pattern on the rest of the shirt resembles the rice-grain weave on the uniform fabric.
A fitted T-shirt you can forget about!
"To guarantee freedom of movement in a garment, you can design it with a loose fit, but this is not practical for an item worn under a uniform. A fitted cut that follows your movements is a better option." That's why we chose a polyester fabric: it follows your movements naturally. For maximum ease when moving your arms forward, the sides of the T-shirt are made from a polyester and elastane blend for stretch!
A passionate team and a growing community:

    Fantastic under a karate gi

    Really comfortable and keeps you cool during lessons.

    Felt it could be a little longer in the body, but this became irrelevant once worn with a gi.

    So like this t-shirt I ordered 2 more!!

    T-Shirt im Wettkampf

    Jeder Judoka sollte wissen dass es den Herren laut Regelwerk nicht erlaubt ist ein T-Shirt im Wettkampf zu tragen.

    Brand's answer :

    Hallo Herr Kaan,

    Erste, habe ich Sie für meine ungefähre Sprache entschuldigt.

    Ich bin französische und Ich bin Muttersprache Französisch.

    Ich habe Ihre Bemerkung zur Kenntnis genommen und bestätige, dass dieses Produkt für Taiso-Praktiker entwickelt wurde, unabhängig davon, ob es sich um Frauen oder Männer handelt. Es ist auch für Judo Praktizierende Frauen geeignet, die an Wettkämpfen teilnehmen und trainieren. Einige Clubs sind bereit, während des Trainings zu sehen, wie Praktizierende Unterwäsche tragen, um vor dem Wettkampf oder im Winter, wenn die Dojos kalt sind, das Schwitzen zu fördern (abnehmmen). Natürlich ist uns bewusst, dass das Tragen eines T-Shirts für alle Wettkämpfe und Shiais-Männer verboten ist.

    Das Detail unserer Produktseite kann in der Tat zu einer Fehlinterpretation des Lesers führen, und es tut uns leid, wenn Sie geschockt waren.

    Camiseta interior para artes marciales

    Tallas muy bien ajustadas, con libertad de movimientos, transpirable y lo más importante reduce el roce al 100% de los kimonos aunque sean muy gruesos, para mí se ha echo muy buen trabajo!

    A deux doigts du parfait.

    Reste bien collé à la peau. Bonne échange thermique. Pas de souci noté en combat par rapport aux prise de kumi kata.
    Pour ma part, Les seuls points faibles sont :
    - un peu trop juste en longueur, sort facilement du pantalon.
    -un deuxième coloris, entièrement blanc ou bleu pour les compétitions.
    Je recommande néanmoins vivement cet article.
    Ps: si vous avez de grosses cicatrices, il permet un confort car évite les frottements avec le judogi.
