The Aqua Glide Swim Cap from Aqua Sphere is a silicone swim cap designed to fit over your ears and has ergonomically shaped ear pockets that will relieve pressure on your ears that can be caused by caps. Inner dimples help the cap to grip to your head, preventing it from riding up as you swim and the roomy fit makes this cap a good choice for keeping long hair out of the way as you swim.
Silicone caps are very durable and ideal for regular swimmers. They will keep your hair relatively dry because of their sleek fit but are not completely waterproof, as is the case with all swim caps.
The moulded ear area does help keep water out of your ears better than an un-moulded cap, but some water does still get in unfortunately.
These hats do keep the water out of the ears.New ones are quite sticky and hard to get on. I have long hair, and there is plenty of room for it under the cap.
the best cap I've tried so far...head felt quite pressured but this is worth it for it's effectiveness at staying in place and providing protection.
