Ride all day.
When planning a long ride, you want to be thinking about choosing the
perfect route, not your shorts getting uncomfortable a few miles in.
Castelli designed the Endurance X2 Bib Short to stay comfortable for
the duration of your ride. Made of Castelli’s Endurance Evolution fabric
in an eight-panel design, the bib short stays in place with a
compressive fit made to help support muscles and wick moisture away
quickly. The bib strap design has been modified slightly with this
generation to help accommodate a wider range of body types.
Castelli made minor changes to its top-tier Progetto X2 Air chamois
to increase breathability and comfort, but didn’t feel compelled to
alter many of the features that have made it so popular. It’s kept the
absence of seaming or folds in the fabric, meaning the insert sits
smoothly against the skin, with a bacteriostatic layer and four-way
stretch in the two-layer design. Sensitive ishial and perineum areas
subjected to the majority of pressure during a ride receive the
perforated padding seen in previous generations of the Endurance X2 to
ensure comfort. Castelli also includes its GIRO3 leg grippers to keep
the shorts in place, which lay flat and have a soft, not sticky, feel
against the skin. On the back of the legs, reflective tabs help you stay
visible to motorists if your long rides start or end without the sun.
