The Seal Tight Sport Cast Cover Adult Arm is specially designed to keep arm casts and bandages dry during swimming and recreational water activities. This waterproof arm cast cover allows users to stay submersed indefinitely in water, and is ideally suited for water sports, or just weekend fun in the swimming pool or hot tub. The Seal Tight Sport Cast Cover Adult Arm is a safe, economical protector for arm casts and bandages during recreational water activities or daily showering and bathing. Made of a high performance thermoplastic elastomer that stretches easily, the cover maintains a waterproof seal. The cover is easy to apply, and does not require pumps, hook & loop closures, or adhesive tapes that may irritate skin. Simply squeeze the excess air out of the bag as the protected, covered end of the cast is submerged into the water. This slowly creates a negative pressure inside the cast which further enhances the suction capability of the gasket. This waterproof arm cast protector is reusable, folds compactly, and lasts for 3 – 4 weeks when used daily. The Seal Tight Sport Cast Cover Adult Arm provides a safe, economical waterproof protector for adults with arm casts and bandages to enjoy water activities.
