In the colder months keeping your legs protected is essential. We have written a guide explaining what to consider when choosing a pair of  bib tights, and have selected some of our favourites from Castelli to keep you riding this winter. 

As winter begins to set in bib tights become an essential piece of kit to protect you against cold and harsh weather conditions. Icy wind, rain, snow, sleet – you name it, Castelli’s wide range of options will have you covered whatever conditions you brave over the coming months.

When the mercury falls, layering is an excellent way of controlling your upper body temperature, putting on and taking off layers depending on the effort of your riding or the large temperature fluctuations that are possible when you’re out all day.

However, when it comes to legs things aren’t so simple: what you have on is what you tend to wear for the duration of your ride, so making sure you’ve got a pair of bib tights that fit well and will keep your temperature regulated is crucial for ensuring you stay comfortable and get the most out of your winter riding.

It used to be fairly common to don a pair of unpadded tights over normal padded cycling shorts. This rudimentary method would keep the cold out, but the extra layers could lead to rubbing and ultimately discomfort on the bike.

All the Castelli bib tights featured here have built in seat-pads – either the pro level Progetto X2 Air Seamless Pad or Kiss Air 2 – leading to a better contact between you and the saddle and reducing the risk of chaffing. These pads utilise the same pro-proven technologies as Castelli’s bib short range – so if you already have a favourite in your summer kit, that’s a great place to start. Investing in a couple of pairs will allow you to ride regularly and reduce the likelihood of saddle sores that comes from riding in kit you’ve already sweated into!

The number of panels used to construct bib tights also affects comfort and feel. The more panels a pair of bib tights has, the more comfortable they tend to be, as the fabric needn’t stretch in so many directions and can fit your body better.

Whether you simply need a thin layer to give skin coverage, more insulation or even windproof or water repellence, Castelli uses a range of fabrics and technologies across its bib tights that means you can keep on riding when the weather takes a turn for the worst, safe in the knowledge that your legs will be protected from the wind and rain.

We’ve put together a run-down of some of our favourite Castelli bib tights that will help you ride right through winter and into spring.  

Castelli Nano Flex Pro 2 RoS Bibtights

Part of Castelli’s RoS (Rain or Shine) line, the Nano Flex Pro 2 bib tights are for riding in the wettest conditions.

These bib tights are made from Nano Flex Xtra Dry – an all-new fabric has a tight weave double layer construction with a water repellent treatment. Although it isn’t totally waterproof Xtra Dry is currently the best wet weather fabric for leg wear available.

The brilliant thing about these pro-level bib tights is that – like the rest of Castelli’s RoS range – they are designed for the wet but aren’t compromised in the dry, remaining highly breathable and perfect for the notoriously fickle British weather.

Reflective panels on the lower leg aid visibility at night, and the Progetto X2 pad completes these top-of-the-line tights.

Castelli Tutto Nano Bibtights

Made from the super soft and incredibly warm Nano Flex 3G fabric throughout, the Tutto Nano Bibtights are exceedingly comfortable. The fabric’s loft has been designed to trap a thin layer of air against your leg to keep your temperature regulated through the autumn and winter.

The Tutto Nanos feature Castelli’s third-generation durable water repellent (DWR) treatment too. Light rain beads off the tights, keeping you dry when those unexpected showers strike.

YKK Camlock zippers on the ankle make for easy closure. When the zipper is angled upwards it locks securely in place preventing any unwanted unzipping. The ankle of the Tutto Nanos is also designed to be closed over your overshoes, stopping excess water making its way into your lovely Sidi cycling shoes.

Castelli Sorpasso 2 Bibtights

With a performance cut designed to offer muscle support and a large comfort range, the Castelli Sorpasso 2 Bibtights are by far our most popular winter tights.

The Castelli Sorpasso 2s are constructed from multiple panels and a combination of fabrics. Thermoflex Core 2 is a hollow 2-layer fabric used on the front of the legs and the knees for extra warmth, better wicking, and protection from the wind. Complementing the protective qualities of the Thermoflex Core 2, Castelli has added extra freedom of movement exactly where it’s needed around the thighs and knees thanks to incredibly stretchy Thermoflex fabric.

The Progetto X2 Air seat and a 3D lumbar support panel hidden inside only help reinforce the Sorpasso’s status as some of the best fitting bib tights available.

Castelli Sorpasso 2 Wind Bibtights

For when maximum protection is needed from the worst weather, Castelli has developed the Sorpasso 2 Wind Bibtights. They bear a close resemblance to the Sorpasso 2 tights but feature Gore Windstopper X-Fast fleece backed fabric on the front of the thighs, and Nano Flex Xtra Dry on the lower legs and backside.

With a comfort range of -5 to 8 ˚C, they’re the perfect choice for deep winter riding as well as for athletes who really feel the chill.

Castelli Light Winter 2

Fortunately, the winter isn’t always bitterly cold or rainy. It can be hard to remember when the weather gets bad but some of the best days out on a bike can be in the crisp winter sun or misty pink skied mornings, especially when such days signal the changing of the seasons and warmer months ahead.

The Light Winter 2 Bibtights are ideal for such occasions. Made for less frosty winter days, these tights offer maximum breathability and a highly lightweight construction.

If you’re used to riding hard and fast with your body generating lots of heat, you may find these tights are right for you even when it is a bit colder. The bib tights have been built to the specification of Team Ineos riders and the cut is inspired by Castelli’s Free Aero Race Bib Shorts making the Light Winter Bibtights incredibly comfortable and suitable for performance at the highest level.
