Castelli Diluvio C Shoe Cover - Cold & Wet 0 - 12c


0 Review

The Castelli Diluvio C Shoe Cover are constructed from high quality 3mm thick neoprene to offer great insulation whatever the weather is doing.

The C stands for colour so now you can match or clash your neoprene shoe covers with the rest of your kit.

Using neoprene for insulation is a real love hate relationship and is always going to be a bit of a compromise. We recommend neoprene for cold damp conditions where you know your going to get a bit damp but its not worth donning the full Tempesta space man outfit. Neoprene is great in that it retains its insulation when wet and is totally windproof. It can also be a bit sweaty this is why we use it it wet conditions. You know your never going to keep 100% of the rain out so just concentrate on staying warm.

Neoprene requires its own care never wash in the washing machine. Always rinse with clean water after every ride air dry. Store dry out of direct sunlight for years of service.

Please Note these Diluvio shoe covers are not impenetrable so expect some water ingress in prolonged heavy rain, they are also not the most breathable cover we do, so one way or another your feet may get damp but they will keep your toes warm and thats the important thing.

We recommend rinsing neoprene with clean water after every ride, avoid direct heat sources and store dry in a cool dry dark place. These are our road race version please check out the All-Road model for commuting and more leisurely riding.

Castelli Cafe - Fitting Guide

Castelli is sized against the rider's physical dimensions the size data in the size guide is the rider size, not the garment size. Castelli garment size is optimised for intended function, So for example an Aero Jersey or Speed Suit are designed to be extremely close fitting, using the material stretch to fit the rider's torso. A race jersey laid on top of a non race jersey of the same size may appear 5cm narrower and not as long - this is intentional as the garment fabrics are designed to stretch to accommodate the riders body shape creating a very close aerodynamic race fit. Never measure old kit to get your Castelli size always measure yourself.

Shoe covers are designed to fit snuggly over road racing shoes only (unless otherwise stated). If your shoes are to the upper end of the size designation and have bulky buckles you should consider the next size up.

1. Snug Fitting; On the bike your jersey or jacket fits snuggly. When riding you don't hear or feel any fabric flapping the close fit helps the capillary action of the fabric to draw moisture from the skin helping you feel drier and more comfortable.

2. Rider Positioning; Fit Off the bike your Castelli jersey or jacket might feel tight across the chest and a little short at the front. This is because the jersey is designed to fit the rider in the riding position. On the bike the fit is prefect with no bunching at the waist and no sagging over the chest. Please keep this in mind when trying on new garments.

3. Fabric Engineering; We use fabrics specifically engineered to wick moisture from the skin or between fabrics, We have created a apparel range that starts with wicking base layers passes through jerseys and onto jackets and shell fabrics. Every element is designed to optimize its specific application - wicking, cooling, thermo regulation, breathability and protection. In order for this to work the fit has to be snug (but never tight)

4. Aerodynamics; The other important aspect of close fitting garments is the aerodynamic advantage they provide. We work closely with professional riders from the Cannondale Team and in wind tunnels to optimise the fit, (again in the important riding position) sleeves are articulated forward to eliminate wrinkles and provide maximum body contact. As an example of our obsession we created the Gabba range of products based around the fit of a race jersey Gabba fits snuggly but provides ultimate weather protection its a key race piece for poor weather conditions allowing athletes to gain an aero advantage over rivals in rain capes.

5. Bib-short Fit; Bib-shorts fit is just as important as a jersey in providing performance - enhancing features such as aerodynamics and muscle support, as well as protecting your bottom from hours spent in the saddle. 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 us to fine tune each material's characteristics to optimize fit and performance.

The Correct care of your Castelli items will vastly prolong the garments life and help to maintain your unfair advantage.

These are our general care instructions - For full care instructions and for specialist cleaning instructions visit our COMPREHENSIVE CARE GUIDE

If garments are heavily soiled with mud or road salt then rinse until the water is clear. Do this in the shower or the sink before washing (cold or warm water only).

If you've used fabric softener in your machine recently, make sure all traces are gone from the machine drum and detergent tray (put the machine on a rinse cycle before washing your kit).

Close all zips and Velcro fasteners and turn the garments inside out.

Try to wash all your cycling kit together and only wash whites with whites colours with colours.

Don't wash cycling kit with bulky or dyed items like jeans or towels.

Machine wash on a warm cycle (40°C / 105°F MAX) using a small amount of non-bio liquid detergent -- we recommend Fairy Non-Bio liquid. Choose a cycle with a double rinse and minimise spinning to reduce creasing.

Do not use powder detergents or any products that contain fabric softeners, conditioners, stain removers or bleach as they may affect garment performance -- destroying wicking treatments, elastics, membranes, water-repellent treatments and sun protection treatments as well as washing out colours. Use of any of the above will void your warranty, too.

Remove promptly from the machine following washing and hang dry or dry flat. DO NOT dry on a radiator or other direct heat source. DO NOT tumble dry

Please note you may have hang tags on garments that have contradictory advice to the garment label. Please be advised that hang tag instructions are for the fabric alone eg Windstopper Fabric not the garment. Your Castelli garment may have additional fabric elements that have different characteristics eg linings, stretch panels, reflective trim. Always follow the above instructions if in doubt please ask us before washing.
