The GOBIK Haru 2.0 ultra-light arm warmers (official reference 15-06-011-001-22) are designed to provide UV protection and light thermal coverage on mild to warm days, as well as during cool summer or spring morning starts. Made from an ultra-breathable, high-stretch micro-perforated fabric, they shield your skin from sun exposure and light wind without causing overheating. Their pre-shaped anatomical fit acts like a second skin, while the upper elastic band featuring an internal silicone gripper ensures a secure hold beneath your jersey sleeves. Highly packable and featherlight, they fold down effortlessly to fit into a jersey pocket.
