The Santini Guard Jacket lives up to the promise of its name, ready to protect you from the elements this fall and winter season, while still being light and packable for practicality's sake. The Guard jacket is intended, both in fit and in price, to be worn by those who are serious about cycling. The cut is race slim, ergonomically contoured for comfort even in aggressive riding positions. The polyester blend fabric is a no nonsense material that locks out the wind and rain without locking in perspiration it's highly breathable for excellent thermo regulation, and the full length front zipper can also be opened for extra ventilation. The jacket itself is very light and can even be packed down into a tight ball and carried in a jersey pocket. Two rear zippered pockets on the jacket carry the cargo you need to reach mid ride, however. The jacket's inner collar and cuffs are lined with a soft fleece for comfort, and of course, reflective details abound for excellent visibility while riding at night. The Santini Guard Jacket comes in the color Black only, and in seven sizes, from X Small to XXX Large.
