To match up with Castelli's Free Donna Tri Top, their Free Donna Tri Shorts offer the same benefits of the Free line of products, with great fitting kit that is unobtrusive and unrestrictive. Tri shorts have different requirements asked of them compared to standard cycle shorts, and these are designed accordingly. The construction is made of panels laid in such a way that there are no seams in the areas that may chafe during the swim, cycle or run.
In terms of fabric, Castelli's Instadry has a Hydrophobic treatment, which means that it is very fast in the water and doesn't absorb the water either. With such quick drying fabric, you won't be weighed down in the next leg or suffer from cold wet clothes. The stitching is flatlock to remain unobtrusive and Castelli's Giro3 grippers are at the bottom of the shorts to comfortably hold it all in place.
The KISS Tri pad is based on their standard KISS 3 pad, but with material taken away from the contact areas to avoid chafing in the run or swim, but still offer plenty of comfort for riding in the aero position.
Temperature range: 17 - 35 deg

Despite being In existance as a clothing manufacturer since 1876, it wasn't until in the late 1940's that Castelli shot to fame with Fausto Coppi, Il Campionissimo (the champion of champions): One of the all time great post war cyclists, a five time winner of the Giro and twice holder of the yellow jersey in the Tour de France.
Armando Castelli was his tailor, and together they created the first silk cycling jersey, a lighter material designed to help when climbing in the alps. The following years saw Castelli create cycling clothing for nearly all the top riders to give them the same edge he had given Coppi; developing the skin suit, chamois, back pockets and zippered collars along the way.
Castelli Sport was founded in 1974 under the iconic scorpion logo to provide premium racing clothing to the next generation of riders, utilising space age (at the time) Lycra for the first time. Something that brought Merckx, Hinault and Moser through the door and gave rise to a new range of innovations derived from the demands of these legendary riders.
Today Castelli continue to build upon their heritage, supporting the champions of cycling by constantly reworking existing designs and materials to produce some of the finest clothing available.
