This is the original good old fashioned rubber inner tube that is durable and can be used for both swim and snow. Tube
in a box is the first inner tube to reengineer a commercial grade inner tube with a short, rubber capped valve stem
because safety matters. These are 100% rubber inner tubes which do not contain any latex and therefore will not cause
any skin allergic reactions. You can be confident that you are playing with a safe rubber inner that will last.
