I use the jacket for several weeks so far at temperatures around freezing or over it. Long Sleeve topsy-ready. The jacket is light, but holds 100% of the wind and closes the throat pleasantly from closely. At 182cm and 85kg I wear a XL. The L could even fit, I felt but as borderline just sitting and just felt more comfortable in the XL. In addition, there is still room for 'nen sweater etc. underneath. The visibility is phenomenal and the jacket gives a good feeling. The only drawback with the yellow jacket, but that you can also see any dirt splashes on it. But that was clear before, right?
