When Castelli developed the original Gabba with the Cervelo TestTeam they knew it would be ideal for cold and wet racing. The first few years it remained a niche product for pro racers and a few people who understood how good it was in the wet. Then they started seeing the pros use it in cool, dry conditions as well. Then it exploded, and now it gets described as ”the best bit of kit I own” or ”the best jacket I’ve ever had”. The Castelli Women’s Gabba Windproof Short Sleeve Jersey is identical to the men’s version except for the fit and the availability of the violet colour. It’s been proven in every single rainy pro race over the past five years, and despite every other company trying to copy it, there’s a reason why the pros are still buying the original Gabba.
