Highly recommend

The bottle is expensive but lasts months swimming 3 times a week and it works each and every time I use it.

Great product

I have used your mask defog since the beginning of the first lockdown when I started daily sea swimming - wonderfully clear goggles for every swim. I have passed the good news on to my friends who have become regular users. Jennifer

Mask defog

Great product, and most importantly, it’s good for the sea. I use this on swimming goggles. Even though it’s for tempered glass masks. Works brilliantly.

Made so much difference !

I love this product..I bought it last year and it has transformed my swims...there is no more stopping to wipe the insides of the goggles.. Just follow the instructions and it works perfectly..

What I really wanted to say was how impressed I am that the whole package is plastic free, really great to see and wish more would follow your lead.


Excellent! Many thanks Lou. Excellent customer service on your part👍. Will definitely be recommending Sea & Stream to my friends and family 👍😊
