SleepWeaver 3D - a breakthrough in soft-cloth mask design Since the SleepWeaver Advance launched in 2010, the soft-cloth mask design pioneered by Circadiance has transformed CPAP therapy for hundreds of thousands of CPAP patients. By replacing the traditional silicone contact material (and even gel masks have a top layer of silicone) with fabric, SleepWeaver masks greatly improve comfort and reduce skin irritation. In addition to this, the flexibility provided by fabric allowed for greater freedom of movement. What makes SleepWeaver CPAP masks \"Skin-Friendly\"? BREATHABLE - Any moisture from the skin or from the CPAP humidifier wicks through the cloth and evaporates into the air stream of the SleepWeaver mask. This keeps the area between the mask and skin dry. CUSHION OF AIR - The mask forms a fabric balloon so that the portion that contacts the face is a cushion of air, rather than a silicone or polyurethane gel cushion. NO RIGID FRAME - The is no rigid frame to press against your face. This lets you roll over on your pillow or sleep face down. NO PRESSURE POINTS - The elastic fabric on the SleepWeaver interface conforms to your facial features. LIGHTWEIGHT - SleepWeaver masks are typically 50% lighter than conventional CPAP Masks. The SleepWeaver range of Skin-Friendly CPAP masks are the softest, lightest and natural-to-wear masks available, and are perfect for those who are find conventional plastic masks uncomfortable. With the SleepWeaver 3D, the soft-cloth concept has been taken a step further The SleepWeaver 3D is the first mask to the feature the new white, elasticated cushion that enables it to better adjust and grip to the skin. This allows it to fit more patients, and with a more reliable seal. In fact, such is the flexibility afforded by the new elasticated fabric that the SleepWeaver mask only comes in one size, as it can adapt to almost any facial size. New butterfly headgear design disperses pressure The SleepWeaver 3D headgear features a new cross-over, \"butterfly\" style design, shown right. This spreads the pressures evenly across the straps for greater comfort, and moves the the band away from the neck where some headgears can cause strain. While the mask itself is one size, the headcomes in two sizes. The medium size is for neck sizes up to 16.5\", and the large is for next size over 16\". Buy it, love it or return it Committing to a new mask can be a risky business; nobody wants to risk spending money on something that may not work for them - particularly if that mask is a radical departure from what they are used to. However, we are so confident that you will love the SleepWeaver 3D that we will provide a refund if you return it within a month. All we ask is that you watch the instructional videos provided below, give yourself a few nights to adjust to the new mask, and if you are one of the few that cannot get it working for you after that then let us know and we can arrange the return and refund. SleepWeaver 3D Features Include: A new wing-shaped stay routes the headgear under the ears, promoting comfort and a great fit. Permanent 360° swivel that provides reliable performance in any position, including over the headboard. Breathable cloth design that prevents fogging that is common in hard plastic masks. Nothing breathes like cloth keeping skin dry and comfortable. For those who want to read or watch TV while in bed, SleepWeaver 3D allows users to wear glasses with the mask on. Almost everyone prefers having soft cloth against their face as opposed to rubber, silicone and other gels. Cloth masks eliminate the need for a cushion or nasal pad.
