This bag is an everyday roller duffle that transitions to a golf travel bag with a single zipper. This bag was designed with practicality in mind. No need to dust off your golf travel bag when getting it out of the attic, simply convert your everyday roller duffle to a golf travel bag when heading to your next golf trip, and then back to a roller duffle when you are heading to a weekend getaway. When traveling with clubs, club protection is important, so your purchase will include a torsion bar for extra club protection.
