The Hurricane is constructed with 100% radio frequency-welded seams and corners (eliminating needle hole leaks), a deeply recessed zipper that runs the perimeter of the unit, and heavy-duty vinyl, creating a truly weather-tough roof pouch. Built USA. Heavy-duty, welded, roof bag sporting the Stars N Stripes! Feeling patriotic? Road tripping across the U.S.? Whatever the case may be we’ve got your roof bag needs covered.
