Cold-weather cycling creates a conundrum. Naturally, we want to stay as warm as we can but if the jacket doesnt breathe well and we get too hot, well begin to sweat. This isnt a good thing especially if we start descending and the wind chill cools our damp jacket. To truly stay comfortable, it is imperative to have something that keeps the elements out yet regulates body temps. Leave it to the wizards at Castelli to produce a piece of kit that defies our expectation of what we know of a winter jacket. The Alpha ROS Jacket is ready for Rain Or Shine and is there to help make all of your winter rides more enjoyable. Whats really nice about this jacket is that it works so well, it inspires us to go ride even in the worse conditions. The Alpha ROS Jackets two-layer construction separates the thermal insulation layer from the wind- and waterproof outer shell. A double front opening to diffuse the cold air when you open up to ventilate on the climbs and prevent overheating. The thermal layer is breathable and is able dissipate heat easily so temperature regulation is an all over affair and not just confined to small pockets. If things heat up even more, the thermal layer can also be zipped down. By crating two layers, each can do their job more efficiently. The thermal piece adds warmth and is more breathable while the outer Windstopper fabric keeps you dry and keeps the chill out. This results in you being less clammy at the top of the climb, and with a quick zip up, you can descend shiver-free since youll be warm and dry. By using Gore’s new Windstopper light rain-resistant membrane and DWR treatment, selective seam sealing, careful seam placement and construction, and a waterproof YKK Vislon zipper the jacket is essentially waterproof without compromising characteristics making it such a great dry-weather jacket too. No matter the weather report or what kind of ride or training you have on tap, this jacket pretty much guarantees a dry and warm experience. The Alpha ROS features raw edges at the waist and wrist—a trend defining top-end gear in the cycling industry of late. Raw edges mean that the hem and cuffs dont contain elastic inserts, so they allow for complete freedom of movement and fit nicely under gloves cuffs. The jacket never rides up, so no tugging it back into position if you have spent time doing an interval in the drops and now you are recovering on the tops. The fit of the Alpha ROS Jacket is actually more akin to that of a jersey. Sin
