Castelli call this jacket their "ultimate jacket" and that is exactly what we think it is: the ultimate jacket. This is Castelli's third generation of Alpha RoS and it truly sets a new standard for winter jackets.
Designed with Rain or Shine engineering, this jacket is in its absolute element in cold, dry conditions. However, rest assured that the GORE-TEX INFINIUM™ WINDSTOPPER® 150 fabric that provides such epic wind protection is also super effective at protecting against the rain too. Castelli have coupled this with reduced seaming and seam sealing on shoulders to further reduce the chances of water penetrating the jacket.
One of our favourite features of the Alpha RoS 2 is the double-layer construction which effectively separates the insulating inner from the wind/water barrier on the outside. This allows you to regulate your ventilation more effectively, reducing that horrible winter jacket sweat we know too well.
If, after all this, you still need convincing, check out the Tech Spec to see why we think this is one of the best winter jackets on the market...

Castelli Size Guide
Where Castelli once had a reputation for making gear that suited only very small Italian folk, the Castelli women's size scale is now very similar to 'normal' UK sizing.
That said, it is primarily designed with a snug fit in mind, so if you prefer more room or are between sizes, go up rather than down. If you are still unsure, feel free to contact us.

Q. What do a 19th century Italian tailor, a designer for the Milan Ballet and the first ever lycra cycling shorts have in common?
A. They are all part of a rich 140 year history that's led to today's most recognised brand in cycling: Castelli.
Throw in a heart attack on a famous Italian climb, family feuds, Olympic gold medals and controversy in the pro peloton and it begins to sound more like a Sicilian soap opera than the backdrop to a cycling brand. But then again Castelli is no ordinary brand.
Today, Castelli's scorpion emblem is arguably the single most recognised in cycling. Iconic is an overused word these days, but the Castelli brand surely qualifies.
We first discovered Castelli on our year long ride through the Americas in 2010, when our founder Liz (pictured) wore Castelli shorts and loved them, so stocking them seemed an obvious choice. But we're almost as captivated by the story behind the name as the kit itself! For the full Castelli story (it's quite a story!), click here.
We aim to dispatch all orders within 2-3 working days, often sooner. Within the UK we use Royal Mail's Tracked service - you will receive a tracking code with your order once it is shipped.
