The Castelli Sinergia Jersey is a classic thermal cycling jersey with long sleeves and a full-length zipper.

Designed to have classical good looks when worn on its own the Sinergia is available in a choice of colours with contrasting Iridescent reflex panels front and back.

The Warmer fabric used all round is lightly brushed for warmth and a luxurious feel but is still exceptionally breathable. While the low bulk makes this jersey great for layering in addition to being worn alone.

The YKK easy sliding Vislon zipper extends the full-length of the jersey, which makes putting it on and taking it off, or indeed mid-ride temperature adjustment, a breeze. The zipper ends in Castelli zen line collar that protects from chaffing while the high double thickness collar also seals out the drafts.

Three rear pockets - the outer two angled for easy access complete the specification for this winter essential.
