These systems are 'one piece' from the bladder to your mouth and by having no joins in the system it eliminates the possibilty of a leak or failure in the system. The velcro foam block makes for quick and easy transitions and is easily re positional to suit where you want the hoses to sit in front of you. The hoses are able to be pulled away into the boat only leaving the hose ends and block out of the boat for travelling.
