Comfort & Fit
The 1137367 Wisp Nasal Mask with fabric frame in Large is intended for users with larger facial features — wider nasal bridges, broader cheeks, or simply who find “standard” / “medium” cushions leave gaps or leaks. Because of its larger cushion, it tends to cover more of the nose and may require slightly more strap tension to seal, but once properly fitted, it can offer a more stable seal with fewer leaks. The fabric frame softens the interface between mask frame and skin, reducing rigid contact points that often cause red marks or discomfort, especially around the sides of the face and near the temples. For people who sleep on their side, the fabric frame and larger cushion can distribute pressure more evenly, making side‑sleeping more tolerable.

Use & Performance
This mask is most suitable for users who prefer moderate mask bulk (i.e. bigger than nasal pillows, smaller than full face) and want minimal intrusion into their visual field (good for glasses, reading before bed). The Wisp system allows fabrics or wraps that can reduce bruising or pressure from rigid frame parts. The Large cushion helps accommodate broader nostril openings, so less risk of pillow tips pushing too deep or being too tight for breathing comfortably. For airflow performance, as with most CPAP masks, assuming the machine is set to prescription, you’ll want to ensure the headgear is adjusted so the cushion seals all around—Large cushions can sometimes need more careful alignment because more surface area means more potential for edge gaps. 1137367

Trade‑Offs & Considerations
Because Large size cushions are bigger, they come with more silicone contact with skin, which means more opportunity for leakage, especially if the mask shifts during sleep. Users may find they need to adjust headgear more frequently or re‑position after movement. The fabric frame though more comfortable, may also retain more moisture or oils, may degrade faster, and generally needs gentler care (washing, avoiding harsh soaps). Also, larger cushions tend to feel more “present” on the face (bulkier), which some people find less ideal for minimal feel. If your prescribed pressure is on the higher end, sometimes nasal masks have more leakage risk than full face masks, so you might trade some leak risk for comfort. Finally, proper replacement of cushion when it shows wear is essential: a worn‑out cushion (stretched, hardened, discolored) will betray even the best design.
