The 686 Authentic Standard Pants set a pretty darn high standard. This 100% polyester oxford shell is equipped with infiDRYR 5 for waterproofing and breathability that can handle mountain riding conditions. TR 4 means that these aren't insulated, so they won't provide much warmth, however these are cut with 686's most popular All Access Fit, so if the earth's frozen over, you can layer up with every pair of pants you own or simply appreciate the roomier fit and layer normally. Fully taped BEMISR seams round it off to make sure the waterproofing barrier is impenetrable. The 686 Authentic Standard Pants are definitely not your standard pants.
