Fast made faster.

This is the suit that started a revolution. Before the San Remo Speedsuit made its debut in 2011 at Paris-Roubaix, the thought of wearing a speed suit for anything but a time trial seemed insane. But after it achieved victory in its first outing, the way cyclists dressed for racing changed forever. In its latest evolution, the San Remo BTW Speed Suit is even faster. On top we use our new redesigned Aero 7 Jersey, which is paired with the reduced-seam bottoms from our Body Paint 4.X speedsuit, a combination that is slippery against the wind. As always, the suit opens completely in the front for added ventilation and easier nature breaks and has three pockets on the back for storage. We've also used our Progetto X2 Air seat pad for comfort during the toughest rides or races. Extensive hours in the wind tunnel have shown this combination to be the fastest yet.

Castelli 'nailed-it' with this BOTTOM (zipper) OPENING = best skinsuit DESIGN period!

15/03/2024

have the Red Version of this speedsuit (last year) but same design and only wear skinsuits (speedsuit) for training/racing and having used many speedsuits over the years.....

Castelli has definitely NAILED IT w/ this zipper (opening) design at the bottom*****

and for a number of reasons.........
solves the problem these suits have always had (no matter manufacturer) = zipper breaking loose down near bottom
and having to fully unzip to go the urinate
PLUS makes way easier to get IN AND OUT of this suit

this is the BEST design for this type of suit
been using this exact speedsuit in red (assuming last years model) as my winter kit (w/ underwarmers/arm/leg warmers) and it's so perfect to be able to pull over and let it out (piss) instead of having to stop and fully unzip........... although haven't needed to use it in this way = would definitely allow for on bike bathroom breaks w/out getting off the bike during a race etc

Great design that hope is incorporated into all future speedsuits and skinsuits in general

do have one REQUEST***
please make this same version in (SUMMER) long sleeve version = have fully converted over to nothing but LS speedsuits for summer training and racing. The lightweight /breathable nature of the fabric along w/ UV SUN PROTECTION provided by LS
