Usually I buy cycling clothes only from Gore, at this price of less than 15 and my favorite color, I just had to strike. Shipping as always super fast, well packaged goods. Should we almost no longer mention at Amazon already. Then the first shock: the color is quite different. Much darker and not as highly luminous. Fabric is 100% polyester, feels heavy but dibasic. Reflectors "disguised" as a manufacturer's logo, the processing appears to be ok. Zip is working properly, but tweaks in the neck a little, because it is not behind feeding. Cut is not too sporty, but not too relaxed. Fits well. So I decided to keep shirt, and dangers also the first time today. With today's temperatures but on a thermal baselayer and a softshell. Conclusion: If the smell of sweat in less than feared at full-polyester, quite warm. Dries to wash quickly, no discoloration or wear. I will like to use the jersey for less sweaty exits, at this price is a strong buy recommendation! Even if the color is wrong ....
