Everybody is enthusiastic about the performance and efficiency of the famous Nano Flex warmers. For winter it's even better to have full tights with this genius water-repellant technology. Bad weather doesn't prevent serious cyclists from riding outside.

The bib straps improve comfort and provide additional protection to prevent cold spots. The tight can completely protect from light rain or drizzle, but even when some water comes through in harder rain it's still the best protection out there. Thanks to the fleece lining, this garment insulates very well and is also great on cool and dry days.

If you're training in Belgium or in any other place with kind of Flemish weather, the Nano Flex Donna bibtight becomes even more valuable.

Who's Behind It?

Q. What do a 19th century Italian tailor, a designer for the Milan Ballet and the first ever lycra cycling shorts have in common?

A. They are all part of a rich 140 year history that's led to today's most recognised brand in cycling: Castelli.

Throw in a heart attack on a famous Italian climb, family feuds, Olympic gold medals and controversy in the pro peloton and it begins to sound more like a Sicilian soap opera than the backdrop to a cycling brand. But then again Castelli is no ordinary brand.

Today, Castelli's scorpion emblem is arguably the single most recognised in cycling. Iconic is an overused word these days, but the Castelli brand surely qualifies.

We first discovered Castelli on our year long ride through the Americas in 2010, when our founder Liz (pictured) wore Castelli shorts and loved them, so stocking them seemed an obvious choice. But we're almost as captivated by the story behind the name as the kit itself!
