    Stylish, warm and extremely comfortable

    Together with a longsleeve merino baselayer, this will be my go to jersey on dry cold days. Incredibly comfortable but very stylish, I love this jersey.

    This thing breathes like a dream

    I like this thing breathes like a dream. Merino is naturally breathable, and somehow, they made it even better. Keeps you from getting all clammy after a few miles, which is a win. I didn’t expect this from a merino jersey, but it’s got a solid aerodynamic feel to it. Not like a race suit or anything, but you’re not dealing with that loose, flapping fabric either. It feels smooth and close to the body. As long as you’re not riding in heavy wind or rain, it’ll keep you comfortable. Just throw it on when it’s cool out, and you’re good to go. Is a no-brainer if you want something warm, breathable, and not too bulky. It’s one of those pieces that’ll make those early-season rides way more enjoyable. Definitely recommend!

    Really pretty perfect

    I wore this l/s jersey in off-and-on rainy weather for two days in a row. I did have to wash it after the first day, but it dried quickly and was ready for the next day without problem. I had an Isadora sleeveless merino base layer on as well, with temps in the mid/low 60s; I probably dress more warmly than many others. When it rained more forcefully I did wear a rain jacket. This jersey was great. Comfortable, and able to “adjust” to the varying cooler and warmer conditions as the ride went along. I wear a medium, and am 65k, 173cm.

    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.
