1, material and manufacturing technology: sweep helmet adopts in-mold technology, and the internal foamed EPS and shell are molded at one time, making the helmet lighter and more compact. However, fassed helmet adopts mode music technology which combines high-end Internet technology with EPS, which makes the helmet have high overall strength and is more suitable for intense riding.

2. Ventilation effect: the helmet has a good ventilation effect, and the vent design is adopted to make the air circulate effectively and reduce the heat accumulation in the head. Fassed helmets want users to have better air circulation than sweep helmets.

3. Lightweight: Because the helmet adopts in-mold technology, it makes the whole structure lighter, feels comfortable, has better performance in relaxation and air circulation, and is more suitable for riding for a long time. Fassed helmet pays more attention to strength and durability than sweep helmet, which makes the helmet slightly heavier and more suitable for intense riding.
