Ultra-lightweight microfiber jersey for the hottest weather and climates. Available in unisex sizes XS-XXL. Machine washable. Sold in pairs. 1 pair Sizing Information: We suggest that the top of the sleeve be worn at the narrower part of your upper arm above the bicep where your arm narrows a bit. The sleeve should fit snuggly but not bind at the upper arm. If you are ordering online, pick the size where your circumferential upper arm and wrist measurements are between the stretched and non-stretched measurements in the table above. If you have short arms or for some women the unisex sizes may be a bit long-- we suggest that any extra length be gathered at the wrist to avoid bunching at the elbow or upper arm. Call if you have questions on sizing and we can talk you through.
