Product description
From cool spring mornings and shortening summer days to early autumn evenings. Made from the finest Merino wool and recycled polyester. This combination of materials will insulate you from the cold but offer enough breathability for comfort in warmer temperatures. The recycled polyester increases elasticity and improves fit, while the Merino wool ensures efficient wicking of excess moisture, excellent thermoregulation and prevents odour. The hypoallergenic silicone gripper on the sleeve keeps your tan line under control, and the back pockets provide enough space for snacks during long hours on the road.

Mr
Very nice top. I was concerned that the fabric might be itchy but it isn't at all. Have worn on three hour rides and is very comfortable. XL fit is perfect for me (86 kgs, 185 cm). Not suitable for the hottest of days but ideal for most summer days in Ireland.Show full review -
Signature Jersey Atlantic Blue
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.Show full review -
Nice product and very good customer service
I am very satisfied with the Jersey, and I have bought two of them (in different colours). I think that the materiel is perfect for the danish weather. Regarding the size I read in the reviews that the product was a bit small. So with my 188 cm. and 86 kg. I choose size XL. When I tried them I thougt they very to big (compared to what I like when I ride). I think they were a little loose around the chest, shoulders and neck. After have them exchanged to size L I am very satisfied with the fit. I guess it is a matter of what kind of fit you like - I like it a bit tight and therefore size L is the rigtht for me with my dimensions. Concerning the exchange proces I am also very satisfied. I experienced a very good customer service and the employee, Natalia, was very helpfull and they did what they could to make the exchange go as soon as possible. I will definitely buy from Isadore again.Show full review -
Nice Bike Gear
I ordered the Signature Cycling Jersey Atlantic Blue/black in size L, since according to the sizing table a "large" would fit. After receiving the shirt, it was just to tight. The exchange went very well and quick until I received it in size XL, which fits perfectly. My size is 190cm / 84kg. The material is a bit thicker than other bike shirts and feels great. I weared it for a 3 hrs ride in about 25 degees temperature and it was perfect. Recommend it fully.Show full review -
Nice Shirt
I’ve bought this shirt and the Woolight Jersey Reseda. Both are very comfortable. This shirt is definately a bit thicker. The Mereno at first feels different than ‘regular’ fabric, but instantly feels natural. Packed the shirt for a cycling holliday for moderate weather conditions. It was very hot (30 degrees) so used the lightweight Reseda shirtShow full review -
Beautifully styled, sublime colour combination
Must be my favourite Spring top. Soft to feel, excellent fit. Wonderful jade green colour and detailed finishing around the pockets. Superb!Show full review -
Perfect balance
I'm a big fan of Merino wool! This jersey is perfect for cyclist like me who leaves in Finland. Here temperatures keeps around 15-25 celsius at summer time so this jersey gives perfect comfort. Not too warm and not too cold.Show full review -
Classy
I bought for it a bit colder summer days. This jersey feels very comfortable. I am 195cm/97kg and it is long enough. The fabric and craft are excellent!Show full review -
Quality product & fantastic service
The Isadore staff provided a fantastic service, always polite, helpful and prompt. The returns service was excellent (ordered two sizes). Also I am very pleased with the product that I have purchased. The product is equivalent to 'Rapha' quality but cheaper. That is praise indeed.Show full review -
High quality, stylish product
I couldn't be more impressed with this high quality garment, which is undoubtably the most comfortable fitting jersey i've ever worn. I love the simple classic styling and the tasteful detailing. The jersey is a close cut but the sizing guide is spot on, i'm a 104cm chest and the XL fits close but not tight...and it looks great on. My customer service experience with Isadore was exceptional and I will certainly be back for more of your awesome products.Show full review -
Comfort, Style & Detail
Like all of the Isadore jerseys, this has the highest level of comfort I've experienced. Another great colour which looks really good and feels soft and cool next to the skin. Everything works on Isadore jerseys, the pockets are large and strong, the tail gripper grips without riding up and zip is smooth and easy. The value is very good too, because I would rather have 1 Isadore jersey than 2 cheaper, mass-market, lower quality ones. Buy one now, you will not regret it. I'm 1.78m (5' 10") and 75kg (166lbs) and size L fits me perfectly - comfortably fitted, but not really tight.Show full review -

Great quality with a personal touch!
I just love the colour & feel of this shirt and the little details on it are amazing. Also the personal note and great communication with the Isadore team is an example on how to keep your customers happy! Will surely recommend Isadore to other cyclist & friends.Show full review -
Very stylish shirt
I really love to wear this shirt. What I love most are the details, the material and the cut. For example the high closing zip in the front is some kind of useful, when there is a lot of wind, so I don't wear an extra scarf. Also the Isadore - sign is stylish. Just some different way of producing quality sports clothing. And especially for cyclists that don't want to wear only the team dresses or always the same styled shirts and trousers.Show full review -
Signature jersey
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.Show full review -
Beau maillot
Hello ! Aucun regret d'avoir passé une première commande, ce maillot est superbe. jolies couleurs (atlantic blue/jet black) sobre et élégant. 1m77 - 72 Kg - 98 de tour de poitrine, j'ai pris la taille M et c'est ajusté. L pourrait me convenir aussi. Merci pour la rapidité de livraison.Show full review -
Gut verarbeitet, gute Qualität
Meine erste Bestellung war in Größe M, jedoch zu knapp. Ich musste das Trikot tauschen gegen Größe L. Der Umtauschprozess lief reibungslos. Das Rückporto musste ich selbst bezahlen. Ich bin 178 cm groß, 75-76 Kg, Größe L passt nun perfekt. Die erste Fahrt mit dem Signature Radtrikot war bei 23 Grad, Sommerwind, ohne Unterhemd. Sehr angenehm zu tragen, nicht zu warm, sehr luftig. Das Trikot wurde danach nur gelüftet, kein unangenehmer Schweissgeruch. Alles in allem erhält man für das Geld eine sehr gute Qualität.Show full review -

Herr
Very good shirt. Due to the German weather I just wore it just two times but it is wonderful. By ordering via internet I often have the problem to find the fitting size. Here are some additional information which could help other users: Size XL, 188cm, 85 kg.Show full review -

Parádny dres
Po drese signature som pokukoval už dlhšie až som si ho musel kúpiť. Páčilo sa mi, že obsahuje merino vlnu a aj vačky na zadnej strane dresu + jeden so zipsom ideálny na malú peňaženku. Samotný dres hodnotím na najvyššej úrovni, veľmi príjemný materiál, síce po spotený smrdí viac ako čistý merino nátelnik, ale to je normálne. Nosí sa naozaj perfektne. Tu by som jedinú drobnosť podotkol, že som si všimol, že sa mi na chrbte začali robiť mierne žmolky, snáď to nebude pokračovať.Show full review -
Uwe
Nun habe ich nochmals eine Ergänzung zu meiner Bewertung vom 05.07.2020. Die Qualität und Trageeigenschaften sind wirklich gut, es hat ja auch seinen Preis!! Ich muss nochmals auf die Größe kommen. Die Trikot sind eng geschnitten, bei 178 cm und ca 76 kg war L die beste Wahl. Hätte ich M gewählt, wären die engen Ärmel noch enger gewesen. Allerdings zeigt sich nun nach 3 Monaten, dass die Farbe des Trikot am Rücken ausbleicht. Das sollte nach so kurzer Zeit nicht sein.Show full review -
Signature Jersey
I just tested the signature Jersey on a sporty 100 km ride. Very comfortable jersey, and beautiful too! Weather was hot (30°C) and I found the jersey to be a little too warm. Not a lot of air circulation to cool you down. Sizing is small (in my opinion). I'm 1m82/78kg, wide shoulders, strong neck and the size M is a bit too small, too tight around the neck and the arms. I got it on second hand so I can't return it. However, the construction seems very good, the colours are beautiful, and the fabric is very soft on the skin. It's the first high-end jersey I have, so I'm looking at details. It's a pricy piece of kit so you don't want to miss.Show full review
