The Q36.5 Sun & Air Knee Covers are lightweight sleeves designed for use in higher temperatures than the Italian brand's heavier Pre-Shaped Knee warmers. Seamlessly knitted with a polypropylene-polyamide-elastane thread, the Sun & Air Covers offer a modicum of thermal protection while also wicking sweat and regulating temperature well. With 50 SPF sun blocking abilities, they're an ideal accessory for riding in climates that demand high UV protection.
