Essential for winter rides
I really like it. It does its job perfectly as written in description. The fit is rather tight I had to reorder XL for me (190cm, 84kg).Show full review -

Perfect Protection for Cold Winter Rides
I’m very impressed with this jersey. It is perfect for cold and dry winter days, providing excellent insulation while still allowing breathability. The fabric feels soft and comfortable. During a long ride at 5°C, combined with a merino baselayer, I stayed warm without overheating. The fit is spot on. I am 188cm and 79kg and a size Large is snug without being too tight. Overall, this jersey is an excellent choice for winter cycling. It offers outstanding protection from the cold while maintaining comfort and ventilation. Perfect for anyone who wants to keep training seriously throughout the winter months!Show full review -

Essential winter gear
This jersey keeps its promises, covering dry and windless weather from late fall to early spring combined with baselayers as the temperatures fall. Worn with a Merino Deep Winter Baselayer it keeps you warm even at -4C. Pleasant feeling fabric, good fit, nice color, I can only recommend it.Show full review -

Very Impressed
The green version has fast become my favourite winter jersey. I usually run cold in winter and this is surprising warm paired with a short sleeve base layer. I'm 175cm/70kg and a Small is a snugger fit than the regular Isadore jerseys, but I think that's part of the design to keep the warmth in. Also means no bulk, so easy to add a fitted outer layer/rain jacket if the conditions change. Love the colour, but guess that's a personal thing. Many kms of use and highly recommended.Show full review -

Nice
Awesome color, super comfy, holds warm well and still wicks moisture efectively. Fit is perfect for me: M for 183cm, 63kg, so rather thin. A tad bit on the shorter side for me, but still feelds good. The zipper is nice, too.Show full review -

Awesome winter jersey
Tested in 3 degrees average on a 3 hour ride with a merino LS base underneath. I felt warm and cozy the entire time, but never too warm and sweaty, so top marks for insulation and breathability from me. Build quality also feels top notch, the fabric is very stretchy. The only disadvantage are the comparatively smaller pockets compared to the merino LS jersey.Show full review -

Essential winter gear
The jersey perfectly matches the promise contained in its description. It covers windless and dry weather from late autumn to early spring, combined optionally with a baselayer as the temperatures fall. Complemented by the Merino Deep Winter Baselayer, it keeps you warm even at -4C degrees. Nice and comfortable material, good fit, great color (Olive ecru) and breathability, I can only recommend.Show full review -

Must have!
Size M. 1.89 cm 79kg. 57 years. Size Guide is good reflection of the size of the jersey. My upperbody is not what it used to be. So I have to loose some weight around the waist to make it a perfect size for me. If I don't its to tight for me. I have not tried the jersey on the bike yet. But I expect that I will only use it with a baselayer as there is not much room for more in my case. Beautiful colour. Very nice fabric. Feels warm and comfortable. Especially with the summer discount I got it's a must have. Looking forward to the winter.Show full review
