These leg warmers are great! I've worn them in extremely wet and windy conditions down in temps as low as low 20's Fht. The spray from the road(even w/fenders)does not penetrate the fabric and I feel virtually no wind. They fit slightly loose(95%)compared to leg warmers that have no wind/wet protection fabric as this protection is a tad less form fitting which is OK to create a slight air barrier which is good in freezing temps. (Depends on size; I use large @ 5'10"-175lbs. if I was an inch shorter I'd use medium.)Really well made w/lots of functional details,stitching&reflective bits. Excellent product!
