  • Beautiful Autumn Jersey

    Eero Saynatkari, 30.7.2016

    Looks fantastic, feels fantastic. Longsleeve merino with a light fleece to add a little warmth. Up here in the frozen north it won’t keep me warm too far into the winter, but you can be sure I’ll be sporting this on the last road rides and the first CX meets. Sizing feels pretty reasonable, and runs a bit smaller than the Long Sleeve Jersey. 176 cm with a 100 cm chest, size M fits just right; shoulders are comfy, no flap around the midriff. Maybe an extra cm or two in the sleeves—but in cold weather, that’s more a bonus than anything else.

  • Thermerino Wonderworld

    Richard Wood, United Kingdom, 30.4.2016

    Received this jersey yesterday and had a ride planned out this morning in the unseasonably cold weather in the UK. Was around 6 deg C when we set off and wore a skin and this over the top and was a perfect temperature, toasty warm. Quality is really good and the retro looks were commented on by the rest of the guys I was out with (not often you get blokes commenting really!). It's a super cool looking jersey and the lining is nice. Feels think even though it isn't. This will be a go-to jersey in my locker. I would describe this as an almost perfect piece of kit for cold weather rides.

  • Excellent Jersey - A must have item for any wardrobe

    Joseph Marshall, United Kingdom, 27.2.2016

    With scores of different types, makes and designs of winter jersey's out there to choose from Isadore have pulled no punches with this excellent merino jersey. It's design is simple and constructed well with the super soft and warm lining coupled with the individual style of the reflective spots on the front and rear of the jersey. I have worn it with a long sleeved base layer and was toasty all ride long. If you are looking for a warm, stylish winter jersey then look no further and purchase now as I can guarantee it will be your go to jersey on those cold days in the saddle

  • Once again, great product

    Robert Winkel, Netherlands, 9.2.2016

    This jacket is absolute fantastic. For me the fit of all Isadore jerseys is good, sleeves, body is perfect for me in size S The neck could be a bit wider for me. I love Isadore because of the comfort, design, fabrics and colours. I am very curious about the new collection!
