It is made with a SpeedFreak ventilated race fabric on the front which is hugely breathable and so perfect for those for high summer efforts.

A Velocity mesh backing to the singlet, this is a wind-tunnel proven choice that's sure to help you cut down on your times and improve your personal bests. With a SnapLock fastener at the lower back, this singlet is able to clip to Castelli's Free Tri Short, giving you security in the fit and the safe knowledge that this singlet won't ride up.

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!
