KneeBees ソフトニープロテクター

These actually stay put through a whole afternoon of my kid scooting around the driveway. The cotton is soft enough that he forgets he's wearing them, and no more scabs on his knees.

My toddler crawls around on hardwood all day and these stay put without sliding down like the bulky foam ones did. The cotton is thin enough that she forgets she's wearing them, and no more red knees after playtime.

I was skeptical about the cotton fabric, but after two weeks of gardening on concrete, my knees are completely scratch-free. They stay put all day and I forget I'm even wearing them, which is exactly what I wanted from something this non-bulky.
