The Swift FX Bella Headgear Loops are a great addition to the ResMed product line because they allow for enhanced freedom. The Swift FX Bella is a great option for anyone who has ever struggled with using CPAP masks because of the discomfort from traditional headgear. The loops that fit behind your ears accommodate for different hairstyles as well as providing the least invasive mask on the market. This is a great option for side sleepers too!
