New Castelli Idro is the lightest, most compact Gore-Tex cycling jacket ever made. Available soon from UK stockists
Castelli has teamed with Gore to create the Idro, a new ultra-light, fully waterproof cycling jacket, that solves that familiar quandary of whether to wear a heavier waterproof jacket for maximum protection or risk a small, packed down cape with limited waterproofing.
Available exclusively through local bike shops in the UK, the Castelli Idro utilises new Gore-Tex Active fabric technology – laminate construction that creates a 'permanent beading surface'. This means water just rolls off, even in the most torrential conditions, with no need for a fabric treatment that diminishes over time.
The Gore-Tex Active material also does without the usual face fabric employed by other waterproof jackets, so no water soaks in at all. This, in turn, avoids the cold feeling often associated with wetted-out waterproofs and keeps weight down to just 123g for a size large. In fact, the material is so light that the Idro can be easily folded down to take up only half a jersey pocket.
Gore's new tech – which is exclusive to Castelli and Gore itself – means that as well as being completely waterproof with fully taped seams, the Idro is also totally windproof. That's often a red flag for cycling jackets, which can quickly turn into a sweaty mess when the heart rate rises, but the Idro is Castelli's most breathable jacket to date.
"We've designed this jacket with an emphasis on light weight and minimum bulk, so it has a minimalist construction as well," said Castelli Brand Manager Steve Smith. "The Idro Jacket is aimed at professional athletes, the Gran Fondo rider or the big mountain rider who will encounter the sudden storm in the mountains and demands maximum protection."
To that end, Castelli has elected for a close-cut aero fit with elastic bindings on the hem and cuffs to keep the jacket comfortably in place. The easy sliding YKK Vision zipper is waterproof while there are also zipped sections on the lower back to allow easy access to jersey pockets and give a little extra ventilation. The addition of reflective stripes on the rear of the jacket will also aid visibility when inclement weather darkens the skies.
The Idro jacket will be available within the next few weeks from bricks and mortar bike stores across the UK. To find your nearest dealer, visit our Castelli dealer locator.
