Bedhead Swim Legionnaire hats are so soft and comfortable over the ears and back of the neck making them a perfect baby swim hat. These swim hats are made of high quality chlorine resistant stretch nylon knit with quick drying ability. Swim hats are best for use in a wet environment - at the beach, lake, swimming pool or splashing about under the hose! If you are looking for a hat for everyday use - we always encourage using our Cotton hats instead (all our hats excluding our range of Swim Hats). A cotton rich hat will be much cooler for everyday use.
