I thought these might work better sizewise than the Mistral I usually buy. However they were tight. If you have a true medium-sized head, I would go with another style. That said, I gave the Leveche a 5-star for the quality and design.
They are very comfortable, my eyes feel great, not dry when wearing them, there is a good seal to it and the foam is firm but soft. It does leave a mark from wearing them like if you’re wearing goggles but I guess that’s a small price to pay for less eye issues. I’m happy with the product and with the customer service.
