The V3.0 version uses Xpure inside G3, the V2.0 version uses G2, the Lite version uses G1, and the filtering effect is G3 > G2 > G1. Regardless of the V3.0 version, V2.0 version or Lite version, there are pressure strips on the nose side, so the air tightness will be better than the magic headscarf without nose side pressure strips, and it is almost the same as a mask.

1. Real anti-haze function
2. Add nose bridge pressure strip
3. Independent lifting function
4. Independent drop-down function
5. All-round elastic, cooling and temperature-controlled fabric, suitable for various head sizes.

The Xpure nano protective layer can withstand 200 washes. If washed once every 3 days, it will last 600 days. It can be calculated based on personal washing frequency. Recommended cleaning methods are gentle hand washing and gentle wringing. If you use a washing machine, please put it in a laundry bag first (those with hard shells for underwear are better) and because you are not sure about the cleaning power of each washing machine, please set it to "soft wash". You can use neutral detergent (soap, laundry detergent, shower gel, etc.) to assist cleaning, but do not add bleach. The drying method is the same as ordinary clothes, just air dry.

1. Full-face helmet users
2. Those who want to protect their valuable helmet lining
3. People who want to wear a helmet that is comfortable and has anti-haze effects.

The differences between the two models are as follows:

1. The Lite version uses Xpure inside G1 filter material, while the V2.0 version uses G2 filter material, which has a stronger filtration effect, and the V3.0 version uses G3 filter material, which has the strongest filtration.
2. The Lite version cannot move up and down freely.
3. The lining of the Lite version is made of special-shaped cross-section fiber, while the V2.0 and V3.0 versions are MCS layers.
4. The hem of the Lite version is shortened, while the hem of the V2.0 and V3.0 versions extends longer and covers a larger area.

Won't. Since there is a seam allowance on the back of the head, and the fabric is very elastic, unless your spectacle frame is very long, causing "the two ends of the spectacle frame hanging ears to protrude from the rear edge of the auricle by more than 1 cm." Otherwise, even wearing glasses is very comfortable!
