My kids both have these goggles and they have been a great investment. the plastic is a bit like silicone and is very flexible rather than rigid so they are not uncomfortable to wear even after an hour of continuous wear. the larger eye area means they fit very well on little faces whilst remaining waterproof. My son has started wearing them in the shower post swimming to stop the shampoo getting in his eyes....not my idea but if it makes hairwash stress free, I am happy. They also come who a very durable case which has kept them protected and scratch free and easy to open and closes securely. overall, would highly recommend.
