    Confort et qualité au rendez-vous

    Le premier point marquant est le confort du tissu : il est doux au contact de la peau, très agréable à porter et offre une excellente respirabilité, même lors d’efforts soutenus. La coupe est clairement près du corps, typée performance, sans être excessive. En taille XS pour 172 cm et 63 kg, l’ajustement est précis, sans plis ni compression inutile. Le maintien est bon et le maillot reste parfaitement en place en position sur le vélo. Côté thermique, il tient suffisamment chaud pour des sorties entre 5 et 10 °C par temps calme. Dans ces conditions, il se suffit à lui-même. En revanche, comme d’autres l’ont déjà souligné, en cas de vent marqué, une couche supplémentaire (gilet ou veste légère) devient nécessaire. C’est ma première expérience avec la marque Isadore, et je dois dire que je suis sincèrement charmé par la qualité de fabrication et le soin apporté aux détails. Mention spéciale également pour le service client : j’ai dû les contacter pour une commande ayant pris du retard, et j’ai été très bien accueilli, avec des réponses claires, rapides et professionnelles. Une expérience fluide et rassurante, devenue assez rare pour être soulignée.

    Perfect fit!

    The material is amazing, super comfortable. I bought a men jersey in size S (175cm, 68kg) and it fits perfectly. Definitely recommend! It is definitely not my last order from Isadore!

    Comfy long sleve Merino jersey

    This is my first jersey from Isadore. It is very nice soft and comfy and it looks fantastic. With a long-sleeve base layer, it is sufficient for riding in temperatures around 8 degrees C. But when it gets windy you will need an extra layer or vest. I have used it so far on 5 rides so I can not say much about durability, but the fabric feels slightly more delicate than Merino from other brands. Im 175m and weigh 87kg size L fits well.
