According to the short video platform of vibrato, the wool length of wool knee pads mainly depends on your personal preferences and warm-keeping needs. Generally speaking, long-haired wool knee pads will be softer and fluffy, with better warmth retention effect, but they are also easier to fall off and knot, and need to be combed and cleaned frequently. Short-haired wool knee pads are relatively more compact and durable, and it is not easy to lose hair and knot, but the warmth retention effect may be slightly worse than that of long-haired ones. In addition, wool knee pads with long hair may appear heavy and not suitable for wearing in pants, while wool knee pads with short hair are hidden and will not affect the appearance.
