Thank You for your interest in Seabags of Florida LLC. As you can see we are just getting started. Basically speaking we took the tried and true concept of a Marine Grade Bean Bag and improved it by adding strapping that makes the bags stronger and allows you to connect 3 or more bags to make a raft in an extreme emergency. They are not intended to be used in the water on a regular basis. They will provide Years of comfort and be there if you ever need them. For more information send us an email or call Paul@Seabagsfl.com Aubrey@Seabagsfl.com Jeff@Seabagsffl.com 407 353 0120
