The Castelli Idro 2 is the smallest lightest Gore-Tex® rain jacket Castelli has ever produced. Is so light and so packable it redefines waterproofs. No longer do you need to choose between carrying a bulky waterproof or a lightweight but non waterproof shell. The Idro is as light as a wind shell, as breathable as a windshell, as compact as a windshell but offers complete waterproofing, guaranteed waterproofing and with SHAKEDRY Technology it never wets out it never gets heavier it never needs retreating. If you are in the market for a new shell make it the Idro.
The Idro 2 is approx 20g lighter than the original Idro it has a slightly longer tail a reflective word-mark and re-engineered cuffs. The weight savings come from ditching the access zip to the back pocket.
Please note. The Idro 2 is designed as the ultimate, ultra light, take with you anywhere waterproof shell. However if you regularly ride in the rain, if you leave home in the rain and ride for 4 plus hours the feature packed Idro Pro waterproof Jacket (at less than 50g heavier) may be more suitable for your needs.
