Black Friday Castelli: Great discounts on clothing from the premium cycling apparel brand

The Venti is Castelli's warmest and thickest winter sock, but not so bulky that it won't fit nicely into a road shoe. A nice ally when the temperatures drop, and a long road lies ahead.

The Perfetto Ros 2 glove from Castelli is thin, comfortable and warm with excellent grip and dexterity. It uses Gore-Tex Windstopper fabric and is available in all sizes.

Castelli's woven Premio bib shorts are top of the range with a lightweight construction that's claimed to be 30% lighter than the competition and to keep you comfortable up to 100F. Expect Castelli's premium features including its top Progetto X2 Air seat pad to help you go the distance. Available with a discount for men and women,

Made from a range of fabrics including Gore Infinium Windstopper and Castelli's own Clima SL insulation, the Fly handles rides in wind and rain. A great option when it's not quite winter jacket weather.

Gear up for your next off-road adventure with Castelli's trail shorts. They mix hard-wearing Cordura with stretchy Lycra for a comfortable fit that will go the distance. They're DWR coated, while zipped vents let you increase airflow on hot days.

Castelli's low bulk, fast wicking summer base layer is a great addition to your summer wardrobe. Its seamless design adds comfort and it's available in all three sizes and either black or white.

Up your summer sock game with these pro-level socks, available in black or white. Their asymmetric knit ensures a perfect fit for both feet, while their low bulk helps keep your feet cool and silver ions help keep them fresh too.

Alternatively, check out the shorter 9cm length at Competitive Cyclist with up to 55% discount.

Castelli's bib short tech filters down to the cheaper Espresso shorts. Available with a discount for men and women, the Espresso shorts have the same Progetto seat pad as the Premios and a tougher Espresso Doppio fabric construction.

For rides in crazy conditions, the Estremo shoe covers provide rain and snow protection and insulation, with a mid-calf design that helps keep water from trickling into your shoes. Castelli reckons they'll keep your feet warm down to 8F.

Castelli gears up for big climbs on milder winter days with the Mortirolo, which is insulated enough for comfort without overheating. A fleece inner to the upper chest and front of the sleeves adds warmth, while the fit is non-race so it's comfortable for a wider range of riders.

Competitive Cyclist has a range of sizes in different colours available for the Espresso tights. They have the same Progetto X2 Air seat pad as the Espresso shorts, while other comfort features include a zip-free ankle and warm Thermoflex fabric.

Gear up for next summer's hot weather with the Superleggera jersey. Its lightweight design offers stretch and breathability, but it still packs a valuable pocket as well as three open ones, so Castelli hasn't scrimped on features.

No rider's wardrobe is complete without a Gabba. This fifth generation jersey offers waterproof front panels, taped shoulder seams and a lighter weight rear to avoid overheating. Along with a two-way zip and three pockets, it's ideal for cooler, wetter conditions.

The Competizione shorts offer Castelli quality at a budget price. A mix of fabrics and raw-edged legs bring claimed aero gains and a Kiss Air2 seat pad offers low bulk comfort. They're another Castelli piece where Sigma offers even greater discounts for colours other than black in a more limited range of sizes.

For more insulation for cooler rides, Castelli's long sleeve jersey has a fleeced inner face and plenty of stretch for a close fit to keep warmth in.

The Unlimited tights provide cool weather comfort thanks to minimal seams, warm Thermoflex fabric and a Progetto X2 Air seat pad. They come with mesh cargo pockets on the legs, to allow you to load up and stretchy mesh straps to keep everything in place.

Castelli's 99g claimed weight Aria jacket provides packable wind protection for days when the temperature sits between 10 and 18C. It's available in three colours and up to seven sizes at Tredz with a discount.

Castelli says that its Core seamless base layer's polyester/polypropylene mix retains less moisture than nylon, with a soft touch and weighing just 45g. It reckons it's a good option for temperatures from 15 to 25C, which should cover most UK summer riding.

Water repellent, windproof, breathable, insulated, reflective - the Raddoppia ticks all the winter cycling boxes an, at 388g claimed weight, won't weigh you down. There's a range of colours on offer at Tredz, including yellow if you want to improve your low light visibility.

Made with Nano Flex 3G fabric, the Tutto Nano shorts provide rain protection and warmth thanks to their brushed fabric. Castelli says they're for winter training, but we reckon we'd get good use of them throughout the UK year.

Aero sleeve fabric helps the Premio Black jersey save watts, while a wicking body keeps you cooler and provides UPF 50+ sun protection. It's available is a range of sizes in orange or sand and there's an even greater saving in black if you're XS or XL.

A mid-weight jacket for less cold weather, the Entrata is made with Gore Infinium Windstopper on thee front and sleeves and a lighter rear fabric. It's cut looser than the Gabba and is more breathable, making it more versatile for the shoulder season.
