Designed to be the fastest suit out there, the Castelli All Out Speed Trisuit is designed down to the detail to make you the fastest you could possibly be on the day you've been training for. 

With an upper portion made from a T1:Stealth Top for all-out aero performance on the bike, this suit is designed for use in all-out aerodynamic positions. Long cut sleeves boosting aerodynamic efficiency and offering a more modern look, this trisuit makes every possible effort to equip you better and make you more comfortable throughout longer distance triathlons. Two rear pockets offering plentiful storage for nutrition, this trisuit makes sure that you can keep energy high as you ride.

The bottom half of the trisuit takes it's inspiration from Castelli's Free Tri Short, which are hugely comfortable and breathable, designed to absorb a minimal amount of water. Finished with a GIRO Air leg elastic at the hem and ensuring that the fit remains secure, you can power on with ease and without distraction, knowing that you've got everything you need to put in a best ever performance. Finished with a KISS Tri seat pad for a low profile and a better experience across all disciplines, for the committed rider wanting to meet their goals.

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!
