The Castelli Promessa Jersey looks so stylish that it could look - to the uninitiated - like you chose it for style over substance. Nothing could be further from the truth!

Castelli describe the Promessa as being for 'extreme performance'. We'd say in reality it's perfect for anyone who takes their cycling fairly seriously and is looking to get better - all the while looking the bee's knees...

The engineered knit material makes the front extra stretchy, which in turn makes it really flattering for all chest sizes, whilst the back has much more limited stretch so there's minimal sagging from the pockets when they're fully loaded for a long ride.

There's extra ventilation for hotter days and discreet design details that can make all the difference on a full day in the saddle. A great answer to so many of your cycling kit questions!

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!
