Winter cycling brings with it many demands and one of the main things to contend with are those bitterly cold winds that sweep in. The men's Endura Windchill Bib Tights aim to defeat this cold-weather enemy via windproof panels in the areas most vulnerable to feel the cold, namely across the front of the legs. With the wind kept out, you'll soon enjoy the warmth as you get up to speed. Meanwhile, in order to ensure you don't get too hot and sweaty, Endura uses luxuriously soft Thermoroubaix® across the back of the legs. While incredibly warm it's also highly breathable, letting sweat escape before you start to feel damp and cold. And last, but by no means least, an eco-friendly DWR (Durable Water Repellent) finish shrugs off light rain and road spray. 600 Series Seat Pad Next comes the on-the-saddle comfort, and for this, the Windchill Bib Tights get treated to the 600 Series Seat Pad. This premium Italian made stretch pad is sculpted from a single block of foam, but with a 'Continuously Variable Profile' (CVP), it places more support where you need it and removes it where you don't. This is complemented by gel inserts for even greater comfort. A super-soft fast-wicking microfibre face fabric, with a permanent antibacterial finish is also brilliant for longer rides, and a mesh panel improves air circulation to prevent sweat build-up. Cold, damp days don't have to resign you to staying inside. Thanks to the Windchill Bib Tights you can get out and enjoy all that winter cycling has to offer, and get those base miles completed, in readiness for summer.

When it comes to cycling during the transitional seasons of the year you need equipment which can offer both versatile weather protection and comfort whether riding fast or slow. The MILLE GT jacket spring fall is engineered to cope with a wide variety of conditions by using technical fabrics to combat any eventuality. Firstly comes Neos Mild fabric, a patented 3 layer windproof and highly breathable 4-ways stretch softshell fabric, it uses a PU bonded membrane to give a high degree of water-repellency. Next, extra breathability is taken care of by Assos' proven circular-knit Triangle textile, deployed on the back panel, ensuring you don't feel cold and clammy on the inside. Then the arms are made with RX fabric, the lightly brushed inner face provides both comfort and insulation. Taken together these fabrics provide a jacket which can be used for faster, more intense rides in cold winter weather or steady rides in cooler spring conditions, keeping you at an optimal temperature and perfectly protected. The Assos regularFit fits beautifully when you drop into a riding position and it gives space for easy layering and complete mobility. Raglan sleeves eliminate shoulder seams and allow a greater degree of motion while a triangulated abdominal pattern ensures the smoothest of fits around the waist.
