The Swift FX For Her features dual-wall pillows that maintain a secure seal while adapting to natural movement during sleep. Swift FX For Her has soft, silicone headgear with a low profile pink back strap for easy, fine adjustments. Because the headgear is so minimal it works well in any sleeping position. Each mask pack includes pink soft wraps for added comfort. The kit includes three pillows (ExtraSmall, Small and Medium) so you can try multiple sizes to ensure you get your best fit.
