These swim goggles were sold by me and picked out by me for my swim team members as for the price in my opinion they are a better product then speedo, my members who all used this product were between the ages of 4 and 15 and spent countless hours in the chlorinated pool water and had no leaks or complaints from any members. the split silicone strap is fully adjustable for any size head child to adult. they are tinted and are fully uv protected from the suns ultraviolet rays. and very comfortable. great product very high quality not a cheap brand. special price available for all 5 just send email.
