If you’re invested in getting the most out of your winter training but don’t want to spend time worrying about unpredictable weather conditions, then the Tutto Nano Bib Shorts are a sound choice.

As with every Castelli garment, the Tutto Nano Bib Shorts have been explicitly designed to give you the very latest fabric technology in a beautifully crafted format.

The Nano Flex 3G fabric used across the garment utilises a combination of newly updated durable water repellent (DWR) treatment and mechanical heat treatment to give previously unheard-of levels of rain protection. Light rain beads off the fabric, keeping you dry when those inevitable rainy spells descend.

On the inside of the Nano Flex 3G fabric, a super soft finish and the optimal loft have been achieved through Castelli’s meticulous research and development. The fabric feels phenomenally comfortable against the skin and the loft traps just the right amount of air above the skin to keep your heat regulated over a wide range of autumn and winter conditions.

This latest update to the Nano Flex fabric not only reflects Castelli’s ongoing commitment to offering you the very best garment quality but crucially means more time enjoying yourself on the bike.

The simple and minimised seam construction across the Tutto Nano Bib Shorts is not only aesthetically pleasing – giving you the option to layer them with a wide variety of upper layers – but increases freedom of movement. A fine-grade mesh bib strap means superior moisture management whilst the latest Kiss Air2 seat pad is ideally suited to long days in the saddle.

The reflective leg inserts are perfect for lower light conditions over the winter months.

If you’re riding regularly over the winter months and need a pair of stalwart shorts that can withstand a wide range of conditions, you’ll be pressed to find a better match.
