The SMART snake bandage makes sense. It uses a clever pictogram to show users how to achieve optimal tension. It starts off as a rectangle and when you have reached the optimal tension, the pictogram will show a square. The SMART snake bandage is made out of a blend of woven cotton fabric, with non fraying edges. It is extremely durable and can be washed after use. The bandage is 2m by 10cm and weighs about 50grams.
