Pas Normal Studios Control Arm Warmers Thanks to their thermal and water-repellent SuperRoubaix material construction, the Pas Normal Studios Control Arm Warmers help to shield the rider from cool and damp conditions during the transitional seasons. Additionally, the material is breathable to prevent a cold, damp sensation from setting in, while its stretch combines with the anatomic cut to donate a perfect fit. Raw cut edges avoid skin irritation and ensure a clean transition with jersey sleeves, and external silicone grippers prevent material slipping when the riding position is adopted. Sizing Pas Normal Studios suggest that the correct size of arm warmers should correspond to the jersey size that the rider would wear. To find the correct size of arm warmers, use the size table to find your ideal jersey size. The correct jersey size for you will then correspond to the arm warmer sizing as follows: Arm warmer size S = jersey size XXS to S Arm warmer size M = jersey size M to L Arm warmer size L = jersey size XL to XXL
