A Lightweight Cycling Jacket for 40 to 65°F
Cool mornings and changing weather: how the Corbah CxM jacket vents as you warm up, and what to wear under it.
In this post
Fall and spring rides start cold and end warm. A heavy winter jacket is too much by the second hour, and a jersey alone is too little at the start. A lightweight jacket that vents is the answer.
The CxM jacket
The CxM jacket is red, with a black zip and a yellow-lined collar, and it's made for rides between 40 and 65°F (4 to 18°C).
Built to vent
- A two-way zipper: the medium-heavy double zip opens from either end, so you can vent as you warm up without the jacket flapping around.
- Zipped side vents: they cool you down, and let you reach your jersey pockets.
- A rear vent: a horizontal vent across the back lets air out without letting rain in.
What to wear with it
Underneath, a Prime base layer keeps sweat off your skin. Below, Stealth bib shorts or any black bib shorts. When it warms past 65°F, swap the jacket for a vest: see vests and jackets and what to wear cycling at every temperature.
