If you got some Exile XM9 or SXT9Q tower speakers on your boat, these speaker socks are a must. Once you are finished out on the water for the day, protect your speakers from dirt and bugs with these. The design allows your tower speakers to breathe without collecting moisture. Since it is super quick and easy to remove your Exile speakers from the tower, these work great for stowing your speakers inside and the carry handles make them easy to transport. Built with UV protective material, carrying handles, corrosion-free zipper, and felt lined interior. Sold as pairs.
