Castelli Idro 3 Jacket
£320.00

Castelli's Idro 3 is a brilliant lightweight waterproof jacket that uses Gore's top line Shakedry technology. It was already an excellent option for wet weather riding and a series of small tweaks have made it even better.

Recent updates include a longer cut for improved coverage, a re-jigged forearm construction, a chunkier zip for easier adjustment, and a new fabric – also from Gore – on the lower rear section that's able to stretch while maintaining complete waterproofness. These changes keep the Idro right at the front of the pack when it comes to top-end waterproof jacket performance.

Gore's Shakedry, which has been around for a few years now, is fully waterproof and incredibly breathable while also being extremely lightweight and packable. The Idro 3's seams and the overall quality of the construction are right up there too.

No jacket featuring Shakedry fabric is cheap and the Idro 3 is more expensive than most. That said, there are precious few jackets out there that can match its performance. If you have the budget for it, this is an exceptional waterproof.
