CASTELLI SIZE GUIDE

Castelli's garment sizes differ depending on whether they're intended for all-out race or more relaxed riding. Here's the definitive size guide for the entire Castelli range.

Understanding castelli sizing

Castelli garment sizing is based on your physical measurements together with each individual garment's intended use.

For example, when picking a race-cut jersey or a rain jacket by your chest size, the jersey will be skin-hugging while the jacket will be sized to allow for other garments being worn underneath. This ensures that each garment works optimally in its given role – giving you the unfair advantage that Castelli is famous for.

While Castelli use standard European fitting guidelines, smaller sizes tend to be cut longer on the basis that performance cyclists are lean, so a medium chest can also fit taller riders.

Our fitting charts for each size show the maximum body size that a garment will fit. This means a male with a 99cm chest would be a size L, however a male with a 101cm chest would be an XL.

Please refer carefully to the sizing guides below for more information on selecting the right size for you.

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.

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.

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.

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

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.

UNI SIZE

Castelli's uni-sized items – such as cycling caps – are designed to fit everyone. Uni-size headwear best suits those with a head circumference of approx 50-60cm.

However, if you have an impressive amount of hair – and depending on the style you wear it – not all hats will fit you even if your head circumference falls within these limits.

Please note, several of the women's headwear pieces contain an opening through which to thread a ponytail, which may suit anyone sporting long hair.

RACE FIT

Castelli race clothing – such as Aero Race jerseys – stretches a lot to achieve a ripple-free fit. It's this snug fitting that gives you the aerodynamic watt saving Castelli is famous for. If you like the design of a race piece, but want a more casual fit we recommend you go up a size.

NON-PERFORMANCE FIT

A non performance piece of Castelli apparel will come out of the bag much more like your T-shirt size. This means a looser fit than race clothing, ideal for long training days in the saddle where speed is a secondary concern to comfort.

Jackets and vests

Winter jackets are sized to fit over a long-sleeve base layer. Waterproof and windproof jackets are designed to fit over a jersey and arm warmers. Vests (gilets) are designed to fit over jerseys.

Castelli Fitting principles

1. Snug Fitting

On the bike, your jersey or jacket fits snuggly. This close fit is essential to ensuring transportation of moisture from the skin to the outside air, keeping you drier and more comfortable.

A snug fit also reduces the garment's tendency to flap when travelling at speed, creating less drag and improving aerodynamics.

2. Rider Positioning fit

Off the bike, your Castelli jersey or jacket might feel a bit tight across the chest and a little short at the front.

This is because the jersey is specifically designed to fit when in the riding position. On the bike, this riding-specific fit is ensures no bunching at the waist and no sagging over the chest.

3. Fabric engineering

Castelli uses fabrics specifically engineered for maximum performance. The brand designs and develops fabrics with the most advanced manufacturers in the world – companies like Gore, eVent, DuPont, Outdry, and more.

When a fabric doesn't exist to fulfil Castelli's vision – such as the water-resistant NanoFlex material – the company creates it.

4. Aerodynamics

Castelli works closely with professional riders and in wind tunnels to optimise material use and perfect cut for a close fit and an aerodynamic advantage.

Sleeves are articulated forward to eliminate wrinkles and provide maximum body contact. Meanwhile, Castelli's obsession with aerodynamic performance led to the creation of the Gabba and Perfetto ranges of race-fit protection garments.

Gabba fits snuggly but provides breathable weather protection. It's a key race piece for poor conditions, allowing athletes to gain an aero advantage over rivals in rain capes.

5. Bib short Fit

Bib short fit is just as important as a jersey in providing a performance advantage.

Enhancing features such as aerodynamics and muscle support, as well as protection offered by carefully designed seat pads for all-day comfort.

Bib shorts should fit tightly enough to support critical leg muscles through compression without inhibiting movement and constricting blood flow.

Using a combination of fabrics allows Castelli to fine-tune each material's characteristics to optimise fit and performance.

TRYING KIT ON

Firstly don't rip the bag open and cut the tags off, just in case the item isn't the right size and you need to return it to us.

When trying on, remember hygiene – always try kit on over clean underwear (we can't accept returns that aren't factory fresh when they come back to us).

Castelli kit is designed for comfort in a riding position so bend over with your arms out to get a better idea of how the garment will fit when you're on the bike.
