Please Confirm Color/Size

The Castelli Mortirolo V Jacket is a versatile cold weather piece that offers superior wind-blocking performance and breathability. Combining Gore® Windstopper® X-Fast on the front with stretch windproof side and shoulder panels, the Mortirolo keeps the wind out for cold weather or mountain riding. The back panel utilizes Castelli's own highly breathable Thermoflex fabric, designed to aid in thermoregulation by keeping you warm and wicking away sweat rapidly.

The easy-sliding full length YKK front zipper makes easy work of the on-the-go ventilation needed on those long climbs. A large reflective panel on the back adds improved visibility for passing motorists, and the 3 rear pockets securely store away all the riding essentials one might need.

Castelli features a form-fit design, if you haven't worn Castelli before it is recommended to size up one whole size. For example, if you normally wear a medium, select a size large.


  • Windproof front combined with highly breathable back for the ultimate climber's jacket.

  • Engineered knit stretch windproof panels on sides and shoulders.
  • Gore® Windstopper® X-Fast main body fabric.
  • Thermoflex rear panel for heat retention and moisture wicking.
  • Reflective panel below pockets for maximum visibility.
  • 3 rear pockets.
  • YKK Vislon zipper.

Buy MUCH bigger than you think you should

I was psyched to buy a new cold weather jacket and thought this would be perfect. Scrutinized the sizing chart closely, had my wife measure my chest, twice, to make sure we got it right. Chart said go with XL, but to be safe I ordered both and XL and XXL. Can't miss, right? Nope. No jacket for you. I'm a big guy for a biker (6 foot, 200 pounds), but not huge, and these jackets must be sized by seriously underfed people, even by roadie standards. So, back into the box they go for a return, and I'm out the shipping charge for that. C,mon BTD and Castelli, it can't be that hard can it?
