ATMOS HB is a true tour flighted line of hybrid shafts – red as the lighter weight & higher launching, blue as mid weight & launch, black as the heavier weight & lowest launch. The ATMOS HB Tour Spec hybrid shafts use the same design concept and technologies as our Tour proven ATMOS Tour Spec wood shafts. These hybrid shafts are geared towards the performance golfer. They have a smooth feeling profile and will promote low dispersion and generally low spin compared to our other hybrid offerings. If you like the performance and feel of the ATMOS in your woods, you will want the ATMOS HB in your hybrids.
