DIMPLES EXCEL Silicone Long Hair Swim Cap with Ear Pocket (2 Pack) silicone SUPREME SILICONE: Made of pure silicone, the supreme material of the swim cap line compared with Lycra and Latex. Lycra caps will only last for 4-8 weeks because they are easily damaged by chemicals like chlorine in the pool. Latex will last longer but Latex cap feels tight and restrictive on the head and tend to snag and pull your hair when being put on or taken off. That is why every swimmer in the Olympic game wear durable, conforming and hydrodynamic caps made of pure silicone. ERGONOMIC EAR POCKETS: Especially designed with ear pockets so that your ears will be covered completely instead of half in and half out with average caps. It also comforts your ears and keeps them warm in the pool. Please note that ear pockets won't 100% prevent water to get into the ears. Please wear ear plugs to eliminate the chance of getting swimmer ear (2 set of ear plugs included in this package). A RELAXED FIT: The soft silicone compound of these caps also provides a relaxed fit to help prevent headaches over long duration swims. They are conforming, but not in a tight, restrictive way. They don't pull hair the same way a latex cap can do, and they are easier to put on and taken off without snagging the hair even for people with chubby head. FOR LONG HAIR: With relative bigger size compared with regular caps, these caps has extra space on the top left to tuck under long hair. DURABLE: Made of 100% quality silicone. They will last for a long time with proper care.
