The first is that it can protect the knees. When you are doing yoga or Pilates, your knees may directly touch the ground. If knee pads or thigh-high leg warmers can protect your knees, then the knee skin will be well protected. Especially when you accidentally fall, the protection of leg warmers may play a good protective role.
Leg warmers with high thighs can keep warm better. These leg warmers can reach the middle of the thigh, so they can replace leggings, but they are much more convenient than leggings. You can put on or take them off in 5 seconds, which may be very important between training sessions. These leg warmers are much thicker than ordinary leggings, and they are fully capable of keeping warm even at -10 degrees.
These thigh-high leg warmers have very good elasticity, they can reach the middle of the thigh and will not slide down. They are only 20 grams heavier than ordinary leg warmers and will not burden the legs. More importantly, they are as soft as wool. When you put them on, it's like stepping into cotton.
