One sport that I practice religiously is swimming,30 laps daily ( 750m). I am thrilled to have found the latest TYR Adult Camo Silicone Swim Cap. The material is flexible and it provides more rooms for my head than all other styles and products. Furthermore, with the generous courtesy discount I received from Sport Authority, I am able to purchase sufficient inventory ( I wear two at the same time)for spares. Thank you for making the effort to stock excellent products for our needs. Over the years, I know I can always counting and trust on your company to select reliable and variety products. Best regards.
