A timeless cycling jersey, cut to a classic design

Product description

The Signature Jersey is intended to offer excellent support during your warm weather riding, whether it’s for five hours at a stretch, or a simple roll to the coffee shop. This is an updated version compared to the first Signature Jersey we released. We listened to customer feedback and made mini-tweaks to the cut and features in order to increase comfort and add practicality. With this update, we have added hypoallergenic silicone tape on the sleeves for better grip to keep your tan lines sharp. We’ve redesigned the extra zip pocket on the back cargo area. And to help keep you visible, we’ve added subtle 3D detailing and a reflective logo on the back.

  • Comfortable, itch-free and soft to the touch
  • Sleeves and side panels comprised of high performance lightweight fabric
  • Excellent temperature and odor control
  • Streamlined slim-fit cut
  • Designed by Martin Velits using his experience from the pro peloton
  • 61% Polyester
  • 36% Merino wool
  • 3% Lycra.

  • Shirt On My Back

    Age MacKenzie, United Kingdom, 8.12.2021 (Signature Cycling Jersey Olive Oil/Chai Tea)

    Honestly I sold my soul and the shirt off my the saying get my dream bike. But the bike needs the best kit to achieve the dream ride. Isadore have come up trumps again with this cycling jersey. Perfect cut and fit for a normal bloke! I am 183cm tall, 100cm chest, 84cm waist and 92cm hips. So I'm quite tall and thin but with a reasonably muscled chest. I am between large and medium on most cycling website sizing charts. So too here. But the support offered online was brilliant and I took the advice to go with a Medium. Nervously to be fair because the sizing chart suggested it would be way way too small. The girl measured the Medium shirt and assured me it would be OK. PERFECT. I bought three! So pleased am I that I have also been back and bought four base layers (equally good quality and fit though I bought one size up on those as recommended) and four Long Sleeved Signature Jerseys also in Medium. Brilliant quality. I've now done several rides wearing base layer, Short Sleeved Jersey and Long Sleeved Jersey here in UK during winter at bang on 0°C. Just brilliant temperature control and comfort. Can't say enough good things. They have my business for life...if this stuff actually does wear out!

  • Signature jersey

    Matthew Spark, United Kingdom, 23.6.2021 (Signature Cycling Jersey Anthracite/Anthracite)

    I'm 103cm chest, 1.75m tall and 80kg. Isadore said size M race fit and L relaxed fit, I got L in anthracite, it's perfect. M would have been too tight. Beautiful item, lovely ribbed sleeves, full zip, real class.

  • Signature Jersey Atlantic Blue

    Des O'Donnell, United Kingdom, 13.11.2019 (Signature Cycling Jersey Atlantic Blue/Black)

    My favourite jersey by some distance. Just replaced a slightly threadbare version 1 after many thousands of kms riding. The version 2 looks just as good with some subtle improvements, looking forward to wearing it in the warmer weather now. Dropped down a size to small (176cm/70kg) and the fit is perfect.

  • Top jersey!

    Miguel van den Wildenberg, Netherlands, 18.10.2019 (Signature Cycling Jersey Orion Blue/Aquarelle)

    I am since July a big fan of Isadore. This is my first Jersey and certainly not my last! Love the colour combination and materials. I am a big fan of merino wool since I have discovered vintage cycling. Size M is just perfect for me: 1.86m/72kg.

  • Really, really good

    Johnny Scholkmann, Denmark, 9.10.2019 (Signature Cycling Jersey Orion Blue/Aquarelle)

    This is my third jersey from Isadore, and it´s really, really good. When the temperature falls, this is the jersey for me. On a 35 km loop, up and down all the time, with 500 hm pr loop, in 15 degrees in Danish fall, with some wind. The first 12 km towards and along the water, cool wind in the head, maybe 11-12 degrees, the jersey does it´s duty perfectly. You don´t sweat, but it´s okay. Then turn into the country, wind in the back, up two steep climbs, 9-12%, each 1 km, suddently 18-20 degrees, the sweat is running, and after one more smaller climb, it goes down again. The jersey function so well all the way, also on the second loop. Even on the third loop, it felt well. Offcause it was´nt dry, but still did´nt get cold downhill. Naturally it require´s a very good baselayer (i´ve several), but still I wonder, how the jersey can function so well, although it´s a bit thicker than many other jersyes. I can strongly recommend this nice, soft jersey.
