The Sportful Fiandre No-Rain Pro Bib Shorts get their name from No-Rain Thermal material, a stretchy, insulating fleece-lined material that consists of ThermoDrytex Plus that’s been hit with Sportful’s nanotech water repellent treatment. Though it isn’t enough to keep you dry in a sideways-blowing monsoon, it’ll hold off normal precipitation no problem. No-Rain Warm is also insulating and very breathable, so if you get too hot on a climb, these bibs will wick away moisture before you freeze on the descent. Of course, the fact that these are shorts means that you can pull on or take off leg warmers as the situation on the road changes. There are a few differences that set the Pro version apart from the standard model, including the chamois (which we’ll get to later) and the bib straps. The Pro’s bibs are Sportful’s lie-flat design, which reduces transitional ridges beneath your jersey. They’re also mostly perforated, letting the breathe and ride light so-as not to interfere with thermal layering. Like the full-length version, the Fiandre No-Rain Pro Bib Shorts feature Sportful’s Bodyfit Pro cut, which is the same fit that the likes of Nibali and Contador wear while training and racing. Some cold-weather gear fits like thermal underwear, producing slack that lets the chamois or the seams get out of place and causing havoc from the waist down. You’ll appreciate the proper fit and compression of this cut, which keeps everything right where it’s supposed to be and supports your thighs, waist, and lower torso. The Fiandre Pro bibs also feature an upgraded insert: the Total Comfort (TC) Pro instead of the standard Fiandre bibs’ Bodyfit Pro chamois. Both were designed for professional use, but the TC Pro is for those who prefer slightly less padding. It also features extended flaps to ease the transition between insert and shorts, helping to prevent irritation during the long training rides of early spring.
