These arm covers feature a ribbon accent, are contact-cooling, and offer UV protection. They are 52cm long and have a thumb hole. They cover your arms completely, providing excellent sun protection even when wearing short sleeves. Worn only 2-3 times for a short period, they are in beautiful condition. However, please refrain from purchasing if you are overly sensitive to items stored at home. I generally ship within 24 hours. Thank you for your understanding and purchase.
