The Free Aero RC Bibtight is made to be your first choice for most of your winter riding. Everything about it is focused on keeping you comfortable and at the right temperature. Every detail, every fabric, every seam will make your winter riding better. This is the tight for those cool to cold days. Not for bitter cold, when you'll want to use a Sorpasso or Sorpasso Wind. Not for mild days, when you'll use leg warmers or a Semifreddo Bibtight. This is for maximum comfort on those days when you need warmth but you're not fighting for survival — those days when you're doing long rides getting ready for the season. Most of the tight is constructed from our Nano Flex 3G fabric. Our third generation of Nano Flex is luxuriously soft, warm, and stretchy. But it also offers excellent breathability, keeps a lot of the wind out, and has our updated Nano Flex water-repellent finish. The lower legs are in our lighter-weight Nano Flex stretch woven fabric with a lightly brushed inside and with leading water repellency. For the rest of the tight we've kept it simple: minimalist Free bib straps that you won't notice, and raw-cut leg endings that are stretchy enough to not need ankle zippers, improving comfort when you pull shoecovers over the top. This is supposed to be your long-ride comfort tight, so the Progetto X2 Air Seamless pad will be protecting your backside.
