    These jerseys are very comfortable, warm and stylish. Very happy with the 2 I have so far. Worn in dry 4 degrees with a sleeveless base layer and signature rain gilet.

    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.
