DESCRIPTION

PRODUCT DETAILS

The Idro 2 is the smallest, lightest, fully waterproof and breathable GORE-TEX jacket available from Castelli.

This jacket will change the way you dress and pack for a ride. It’s so small you’ll find yourself stuffing it in your back pocket for rides with even a remote chance of rain, just because it takes up so little space. And you’ll be extending your rides into conditions when rain is forecast because you know you’ll be perfectly covered. 

Using GORE-TEX SHAKEDRY™ two-layer fabric, Castelli has constructed the most minimalistic jacket possible but one that still covers all your needs. Its a close cycling fit with an extended tail and a waterproof zipper. It also features a reflective wordmark and some small red styling touches and that’s about it. Its the fabric and the sheer lack of bulk that is the star here.

Compared to the Idro Pro Jacket, this one packs up smaller than a gilet and is made to go in your pocket for every ride, yet it still provides essential protection when called into duty.

3XL 115cm 104cm 116cm 87cm

Men's and unisex Castelli sizing is based on your physical measurements and the garment's intended use. Race items are designed to use fabric stretch to achieve a very snug fit; as such physical garment sizes vary within the range. Please don't compare sizing with other manufactures. The sizes shown above are for the maximum size, so someone with a 99cm chest would be a size L. If you have a 101cm chest then you're an XL.

Women's sizing

A - Chest B - Waist C - Hips D - Inseam
XS 79cm 63cm 87cm 75cm
S 84cm 68cm 92cm 76cm

L 94cm 78cm 102cm 78cm

Women's Castelli sizing is based on your physical measurements and each garment's intended use.

Racier items are designed to use fabric stretch to achieve a very snug fit, as such physical garment sizes may vary within the range. Please do not compare sizing with other manufactures.

Please note that sizes shown above represent the maximum size for the garment, so someone with a 88cm bust would be a size M or if you have a 91cm bust you are a size L. You do not need to size up for jackets or vests.

Glove sizing uses the physical measurement around your hand as displayed above. Gloves should be snug: if you find the palm fits loose when in the cycling position you will probably need to size down. Always use the pull tags to pull on and remove the gloves. If there are no pull tabs fitted, roll the gloves off so they end up inside out.

F - Women's EU Shoe Size 35-37 37-39 39-42 - - -

Castelli shoe covers are designed around an EU shoe size that will fit snugly over a sleek road racing shoe of the corresponding size. If your road shoes are bulky, wider than traditionally narrow Italian shoes such as Sidi, or shoes that feature adjustable heels or dial-style closures then consider sizing up.

If you have a side dial-style closure we don't recommend a side zippered shoe cover, instead choose a design with choose a rearward zipper.

If your shoes are designed for touring, commuting or mountain biking please select an All-Road shoe cover as Castelli's standard shoe covers will not fit this style of shoe.

Shoe Covers (unisex)

CASTELLI SIZE S/M L/XL 2XL
F - Euro Shoe Size 36-40 40-44 44-48

Multi-size Castelli shoe covers will fit snuggly on most shoes in the suggested range. However, please consider sizing up if your shoes are wider than standard or have large exterior dial-style buckles or if you are towards the top end of a size on the guide above.

So for example if you have a wide fitting shoe with external buckles and are size 44, consider a 2XL cover rather than squeezing into a L/XL cover.

As with Castelli overshoes, If you have a side dial-style closure we don't recommend a side zippered shoe cover, instead choose a design with choose a rearward zipper.

If your shoes are designed for touring, commuting or mountain biking please select an All-Road shoe cover as Castelli's standard shoe covers will not fit this style of shoe.

Castelli warmer sizing relates to your jersey or short size and your body weight.

Warmers have a lot of stretch and for designs incorporating Thermoflex fabric, you can size down.

However, we would not recommend sizing down for Nano Flex and Nano Flex Plus products.

Castelli casual clothing is designed to give a loose fit when correlated to your jersey size. So if you wear a Gabba in L, you will achieve a casual loose fit with a L-sized T-shirt. Bearing this in mind, if you prefer a closer fit you may wish to size down.

For shorts and trousers, please select the same size as you would for bibshorts or tights. Women's T-shits and hoodies are designed for the female form. All other casual pieces are designed to be suitable for both men and women.

Sidi fitting guide

Like many handcrafted Italian shoes, Sidi cycling shoes feature a slim fit, the equivalent of a ‘D’ width. In our experience, if you’re usually a 45 in cycling shoes, you’ll be a 45 in Sidi shoes.

However, you also have the option of Sidi’s half sizes. These use the same length soles as the main size (i.e. 45 and 45.5 are the same length) but use a larger volume upper. This is perfect if you need a touch more width, have slightly higher arches or use an insole that takes up some of the volume of your shoe.

The volume and fit of the shoe is also affected by the closure system utilised. We’ve found that the combination of a central dial with the Soft Instep 4 strap means the Sidi Wire 2 has a slightly roomier toebox than the rest of the range, making it ideal for those seeking Italian styling with a little extra wiggle room.

If you need more volume, Sidi’s range of Mega fit shoes feature soles that are 4mm wider and have larger uppers for those with higher volume feet or deep orthotics.

Of course, everyone’s feet are different and slipping the shoes on will give you the best idea. We’d recommend trying them on towards the end of the day or even after a long ride to give your feet a chance to swell to their maximum size.

If your toes are brushing the end of the shoe, they’re too small. If you stand on tiptoes and the heel of the shoe doesn’t lift with the heel of your foot, creating a gap, they’re too big.
