Today I on April 3, the same time my new long-sleeved cycling jersey tried at about 9 ° and medium high winds. And it did not disappoint me! Had not thought of that as well and it warmed the wind keeps. Since I did not drive very fast and angstrengt, I also did not produce as much personal warmth that is, it would probably on the bare arm still sufficient even at 5 °. It fits snug, but not too tight, is very flexible, has a firm elastic degree at the bottom and various pockets to store gloves, cakes and the like. The price of just 30 Euro is absolutely fine. From me a strong buy recommendation!
