The Stream2Sea ecosafe Mask Defog is based off their shampoo that is tested to be biodegradable and safe for fish AND it works brilliantly!

Testimonials (including from TSC instructors!) have been rolling in that it holds up to multiple dives, and the bottles are sustainably made from sugarcane resins and recycled plastics. This mask defog is just another way to protect what we love and see clearly while doing so!
