Signature Merino Tech Jersey
Universal technical merino jersey with synthetic panels for increased functionality
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.

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.Show full review -

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.Show full review -

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.Show full review -

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.Show full review
