The SunGuard Headband is a fun, sporty accessory to add to your wardrobe. It can be worn as a headband or scrunchie to keep your hair pulled back, or you can wear it around your neck or over your face as a mask. Aqua Design has re-invented the typical multi-headband-neck-face protector by offering five sizes in a flexible four-way stretch fabric. Designed for use in and out of the water, the soft 100% AquaPoly fabric is breathable, wicks moisture and is quick-drying. The flatlock seams make it extremely comfortable to wear all day long and the durable design featuring stretch-seams sewn at the open ends reduces curling and fraying. Our multipurpose face/neck tube is rated UPF 50+. Save on the cost of sunscreen lotion and protect neck, ears, face, and head with the SunTube Face Mask, which blocks harmful UV rays 97% - 99%, even when the sky is dreary. Available in seven proprietary sky-ward 3D camouflage water print colors, the SunGuard Multipurpose Headband coordinates perfectly with the full line of Aqua Design Products. It can be worn as a matching beanie, headband or hair accessory. Moreover, for those who wear glasses and sunglasses, you will be able to breathe through the mask, so your glasses are less likely to fog. Our research team discovered that one size does not fit all when wearing sun protective tubes. So, we decided to offer five sizes to choose from, extra-small to extra-large, that way you will be sure to find the right one that fits you and will not fall off. Suggested wear is a hair accessory or face mask for sun and/or wind protection, fishing, gardening, kayaking, rowing and running. Wash cold and cool dryer or line dry.
