The Long Sleeve Jersey quickly became a staple in our winter collection, made from an intelligent Merino/poly mix. These jerseys provide breathable, non-bulky insulation. Ideal on their own or with a short sleeve baselayer for early autumn rides. And they can be easily used as a mid-layer for those frigid December days.

    Great!

    I’m 183 cm 75 kg and size M fits perfect for me. Very good quality and cut! Great feeling on the ride - never too cold or too warm. I highly recommended this piece of kit.

    The signature Long Sleeve thermal jersey is outstanding in so many ways. Fit is perfect and the sleeves don't ride up. Great weight for 40F pairs perfectly with the Thermal vest. Quality is apparent across all of the isadore kit that I have purchased. Bravo!!

    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.
