Sanremo 4.0 Speed Suit
The Sanremo 4.0 Speed Suit from Castelli brings together the comfort
and aerodynamics of a speed suit with the long-mile functionality of a
traditional kit. While most speed suits are limited to short criterium
and time trial applications, the Sanremo 4.0 extends its utility to
almost any type of training ride or race.
The top half of this dynamic duo is a jersey designed in the style of
the Aero Race, which is constructed using Castelli's Velocity Rev2
fabric. Velocity Rev2 features a tightly-woven construction to usher
airflow over your body as you ride. It's extremely comfortable since the
body fabrics will keep you dryer and cooler than the simple Lycra
utilized in most skinsuits. Two rear pockets, something of an anomaly in
the speedsuit world, provide valuable space for carrying spare tubes, a
handful of gels, and other ride necessities.
The bottom half of the suit is Castelli's popular Free Aero Race 4
Short, which is designed for aerodynamic racing and comfort during long,
back-to-back rides. Castelli starts with a blend of breathable,
moisture-wicking materials when constructing the shorts, using its
proprietary Forza fabric to achieve a contoured fit across the thigh
panels of the shorts that will maintain gentle compression throughout
hours spent pedaling in and out of the saddle. Dimpled Vortex fabric
complements Forza facilitates more efficient aerodynamics on the
wind-exposed areas of the shorts along the outer legs and lower back.
The large leg cuffs are Giro4, which offer a smoother, more
evenly-distributed pressure over the skin.
Castelli lines the suit with its top-of-the-line Progetto X2 Air
chamois, featuring a luxuriously soft arrangement of multi-density foam
strategically placed to provide support on 100-mile road races or
60-minute crits alike without inhibiting your movement in the saddle. A
four-way stretch outer layer with an anti-odor treatment and soft,
micro-denier surface blends the chamois in with the rest of the shorts
for a smooth, unified fit.
