We always push our Thinkers to make sure to stay out of the sun during peak hours, to seek shade when possible and....to wear protective clothing. The Thinksport Sports Cap is a very stylish way to tell the sun, you're not having it. It is also a great way to tell the world that you're focused on embracing an active, healthy lifestyle. Who are we? We are not a sports bottles company. We are not a sunscreen company. We are not a food container company. We are a safe products company. Designed for thinkers by thinkers. All of our followers are part of our story. Every thing that you purchase is a "vote". A vote for the movement away from products laden with harmful chemicals and morally bankrupt organizations. The Thinksport Sports Cap is a one size fits all hat. It has an easy to adjust Velcro back.
