Debut Merino Air Jersey

Lightweight and breathable merino jersey with effective thermoregulation for summer riding.

Explore More

Merino wool is soft to the touch and prevents overheating even during hot summer days, maintaining its properties even when sweating. Silicone tape all around the entire lower perimeter keeps the jersey in place, and 3 back pockets provide plenty of room for snacks and small valuables. Complete with one-way YKK™NATULON® zipper and reflective logos. We used leftover materials from previous seasons, including zippers and silicone tapes, to make this jersey an extremely environmentally friendly piece.

Find me a better jersey for the money

Easily the best bang for your buck of all the jerseys I’ve owned. And I’ve owned many. Please release more subtle earth-tones!

Another great jersey

Like all jerseys I own from Isadore, it fits like a second skin. I am 75kg and 1.78m and wearing size S. It fits tight but still comfy. Great fabric and style. I am happy that Isadore still offers plain, decent designs. The only thing I am missing is a small zipper pocket for my key/money/cards. Also the smell is very industrial. Combines nicely with the Light Sleeveless Baselayer in size S.

Debut Merino Air Jersey

The colors are awesome (as with any other Isadore product)! The material feels great to use—soft and nice to the touch, warm, but also well-ventilating. I like that the debut line is stretchable and adjusts to the body shape. The pockets are great and can easily expand. A minor downside is that some threads are already visible after just a few road rides. By the way, I'm 182 cm and 98 kg (with a body shape resembling that of a rugby player), and XXL fits me the best. It was quite a hassle to find the correct size for me, as I don't have a typical road rider's shape. I got four products from Isadore and can recommend them to anybody (already thinking about other purchases).

Excellent Jersey Great Value

Very comfy jersey at a good price. Love colour looks more expensive than it actually is. No zip pocket but that’s not essential for me. Bought size XS which is a great fit for me - can’t fault it! 175cm 55kg

Perfect essential jersey for summer

The size guide was helpful and on point for me (182/68 - S). The fabric is great for summer rides, breaths perfectly, the fit is comfort-focused rather than race.
