Replacement "reduced size" headgear strap for the Philips Respironics Pico nasal CPAP mask. All Pico masks in every size of mask cushion (small/medium, large, and extra large) come with the "regular" headgear strap. The reduced size headgear strap is a smaller strap option. The reduced size headgear strap does not come with the Pico mask, so if you've purchased the mask, and if you think the headgear strap that came with the mask is a good size, then you should order the regular Pico headgear strap and not this reduced size strap. The headgear strap is the adjustable neoprene-like strap with hook-and-loop closures for adjustment at the four anchor points of the mask frame. The headgear strap does not include any other mask components.
