Castelli Chpt III 1.91 Arm Warmer

David Millar knows what performance looks like, after 17 years at the top of the sport. The Castelli Chpt.III 1.91 Arm Warmer that he helped to design certainly reflect this. The fabric has slightly tighter knit with higher loft fleece. This helps to make the warmers more stretchy and supportive, something that is of the utmost importance for a riders legs that are, in theory, moving round at speed.

An elasticated hem at the top of the warmers help to hold them in place and a turn-able cuff at the bottom reveals a reflective strip. Easy to take on and off, the warmers can be simply rolled up or down your arms and folded and stowed in a jersey pocket.

Please Note: For sizing we recommend that you opt for the same size that you would wear in a jersey as the arm opening will be the same size.
