When gearing up for cold-weather cycling, we typically accept that things like fit comfort and aerodynamics will be sacrificed in favor of wind-stopping power and warmth. Leave it to Castelli to refuse this sacrifice with the Sanremo 2 Men’s Thermosuit, a piece of kit designed to offer the aerodynamic benefits of a bulk-free fit without the restriction of bibs–all while preserving the benefits you’d expect from the company’s flagship cold-weather technology. The Sanremo 2 uses a mix of fabric panels in strategic locations to create a microclimate in the sliver of space between your skin and the Thermosuit. The Windstopper X-Lite fabric leads the charge on the upper portion, offering 1. 4 billion impossibly small pores per square inch that guard your microclimate jealously. They don’t let wind in, but they do let moisture and water vapor out. This isn’t just based on vague marketing copy, though; the science behind Windstopper X-Lite is measurable in a rating called CFM, which stands for cubic feet per minute, used to measure the volume of air that passes through a fabric in–you guessed it–one minute. In order to be considered truly “windproof,” a fabric must register a CFM of equal to or less than 1. 0. The Windstopper X-Lite fabric actually beats this rating, so you’re guaranteed a literally windproof top. The bottom portion is a mix of Thermoflex and Thermoflex Core2, using the former for areas that need more stretch and the latter in areas that need more protection. Both iterations of Thermoflex use hollow-core yarn to increase the size and insulating power of that thin microclimate. The whole Thermosuit is water-resistant and lined with a brushed interior so it’s comfortable against your skin without any need of a mediating base layer. The fit is the same bulk-free, race-worthy fit you’d enjoy wearing Castelli’s Gabba Long-Sleeve Jersey and Sorpasso Bib Tights, less two elements: The bibs and the gaps. We often find that bibs are unduly constrictive on col…

If you’ve been subjecting yourself to blasts of chilly air while riding in traditional cycling shorts, look no further than the Castelli Men’s Evoluzione 2 Knicker for additional coverage required for cool conditions in late autumn and spring. This basic knicker forms the basis for Castelli’s range of knickers, providing excellent value, but without sacrificing the form-fitting support or plush padding you’d find on more premium offerings. Case in point, the ProDry Soft 2-layer fabric actively pulls moisture off your body to better regulate body temperature. It’s comprised of a polyester knit inner layer for a smooth feel and moisture-wicking comfort, paired with a nylon outer layer for a bit more support and shape retention over time. Unlike other basic knickers on the market, the Evoluzione 2 comes with a top-flight KISS Air chamois comprised of infinitely variable thickness foam that’s tapered along the sides for flexibility and thicker along the rear to relieve pressure on sensitive areas. It employs a seamless microfiber lining with dimpled surface that speeds up evaporation of sweat, as to eliminate the damp, irritating feel of a soaked chamois. Additionally, this knicker comes with InMold silicone leg grippers with a clean edge finish to prevent the bottoms from riding up.
