I am a bit clumsy, that is why I always have one of the bandaid and alcohol swabs in my wallet.
I prefer the fabric elastic ones than the waterproof plastic alternative. The fabric plaster is breathable and easily dry up after getting wet. It is tough and resistant to scratches. However, the string will slowly come off after about half of day. Also, it seems to absorb dirt and get dirty easily. That can be used as an indication to change it.
I bought 4 boxes these time to refill my first aid box in the house and cars. Great product.
