Rheos Sunglasses – 1 Pair

The basic principles of buoyancy apply: when an object displaces water the heavier of the two sinks. Meaning, if 2 oz. of water is displaced and the water weighs just barely more than the object, then the water sinks and the object floats. If a second object weighed the exact same amount and displaced only 1 oz. of water and the water weighed less than the object, then the object would sink and the water would “float”.

With that in mind, our frames are made of the highly durable and ultra-lightweight TPX® material. Due to its unique manufacturing process, these frames weigh approximately 30% less than similar sunglasses molded in polycarbonate while maintaining a hyper-durable structure to ensure its comfort for long-term wear and floating capability.

Since our shades weigh less and displace the same amount of water as standard frames, ours float while theirs sink.

TPX® requires no drying before molding and consequently suffers zero deterioration when in contact with water to maintain its durability over extended periods of time.
