Signature Merino Tech Jersey

Universal technical merino jersey with synthetic panels for increased functionality

Explore More

The main material is a blend of synthetics and merino. Synthetic fiber on the outside has quick-drying properties and increased abrasion resistance. Merino wool loops on the inside create a 3D structure that allows microcirculation of air. Thanks to this feature, the material dries faster, is more breathable, does not stick to the skin and is pleasant to the touch. The sides, sleeves and panel under the back pockets are made of lightweight, perforated synthetics for efficient moisture and heat wicking in critical zones. Silicone tape around the entire bottom hem is complete with reflective logos for better visibility. Three rear pockets plus one zippered pocket provide plenty of room for snacks and valuables on long trips. One-way recycled zipper is covered with a flap and zipper garage that protects the bibs and leather from abrasion.

Merino ist Top

Ich verwende nur noch Merino Shirts, weil diese erstens ein angenehmes Tragegefühl hat und geruchsneutral ist. Das Shirt ist atmungsaktiv und hat einen schönen unaufgeregten Design mit dem gewissen Understatement ohne dass man mit übergroßen Lettern Werbung macht. Die Passform ist sportlich körpernah und ich empfinde es etwas kurz. Trotzdem komme ich gut an die Taschen. Top ist der seitliche Reisverschluss um etwas Geld, Schlüssel etc. zu verstauen. Ich bin zufrieden und bleibe bei Isadore.

Merino without worry

I use this jersey about 10 times when the wind was around 12-13 m/s and the temperature was around 20 degrees. Compared to regular jerseys, it is very breathable, so sweat seems to evaporate quickly from the base layer. I find it very useful because it is made of merino wool, which prevents sweat from cooling down. This merino product is also durable even when washed in a washing machine, so I can use it without worrying too much.

Great jersy

Nice and comfy shirt. Wore it on 160km ride in sun now I’ve nice tan lines. Merino works as intended as well; warm when cooler and cools when getting hot. Dries quickly. 191cm , 80,5kg, chest 95,5: M, fits nice and tight.

really versatile, check sizing

I've now worn this on two rides, each one starting out at about 60º/15.5c or a little less, with temperatures reaching 70º/21c. Both times it was perfect, once w/a sleeveless base layer and the other with a short sleeve base. I have to think this jersey will only be better when the temperature is a bit cooler. Pay attention to sizing, however. I'm 66k/173 and the medium is Italian tight.

Nice Jersey for warmer conditions

I like this Jersey as it is very light and comfortable, nice fabric and a cool colour - perfect for warmer conditions. I am 176cm and 80kg and first bought it in Size M, which was too tight for me as I am more the athletic bodytype with a wider chest and shoulders - size L fits now perfectly. Customer Service Support was very helpful to change the product.

Good quality, slightly small sizing.

I ordered a medium, as that size fits me well for baselayers and bibs. When it arrived, the jersey seemed like excellent quality and really nice material. However it felt very tight when trying on, and I couldn't do the zip all the way up. Returning for a refund was very easy and quick. Will try a size large next time.

Perfect Summer Jersey

I am 175/73 not skinny neither overly muscular and size S fits snuggly. Size M wouldn't be big but might have been somewhat crumpled on the front. Material is stretchy and airy, not sure about the durability yet, but sure is nice and comfortable. Will buy another one.

Not the best one

I have many Isadore pieces, it is my favourite cycling brand. This jersey does not live up to my expectations regarding breathability. With any possible baselayer, even at 16-17 degrees, sweat stains appear. This is the only Isadore jersey I have, where it happens. Since the colour is a bright one, it is quite unpleasant look. Otherwise the jersey is very good regarding design and fit. A bit disappointing.
