Product Description

Bright, Light & Easy to use

The Billy Drybag Tow Float easily attaches around the swimmers waist with the adjustable waist-strap and leash, the Billy Drybag will then float above the swimmers thighs, out of stroke range whilst swimming.  The float leash is adjustable in length so the swimmer can alter it to their preferred length.
The float is ideal for holding onto in the water to when taking a break or to boost confidence.

Drybag Storage Compartment

The storage compartment is separate from the 2 inflatable air chambers. Once the storage compartment is sealed, with the swimmers items inside, the air chambers can be fully inflated so they are stretched taut which reduces the drag. The float can be used in all swimming conditions, with or without your gear inside.

Used correctly the Billy Drybag floats are waterproof but we recommend electronic and other valuable items are sealed inside a waterproof pouch before placing inside the dry bag tow float.

Optimised Streamlining

The leash attaches to the float via a karabiner clip under the front of the float. This low tow point along with the float shape, valve position and direction of tow have all been designed to reduce drag.
