In addition to complete systems, HEAD Balloons is the leader in the development of Replacement Envelopes. HEAD Balloons was the first to obtain FAA Supplemental Type Certificates which allows the use of HEAD Balloons' envelopes with almost any other manufacturers' basket and burner systems. Now the HAND CRAFTED QUALITY and RUGGEDNESS of the HEAD Balloons' envelope is available to all of you that have a tired, worn out lightweight balloon envelope. HEAD Balloons has seen the need and responded to the balloon community's demand for QUALITY, TOUGH and REASONABLY PRICED Replacement Envelopes.
