A physiological pants, comprising:

• a clothing layer, constructing a piece of clothing, wherein the clothing is formed with a main opening for the torso to pass through and two secondary openings for the limbs to pass through;
• a waterproof layer attached to the clothing layer, wherein the waterproof layer is formed as a surrounding wall to enclose a water storage space with a water absorbing opening;
• a water storage layer arranged at the bottom of the water storage space;
• a water-permeable layer arranged in the water storage space and contacts with a surface of the water storage layer close to the water absorbing opening, wherein the water-permeable layer containing an antibacterial agent;
• and
• wherein the water-permeable layer includes a first layer body woven by a plurality of first threads and a second layer body woven by a plurality of second threads, the first layer body is formed with a plurality of first water-permeable holes, and the second layer body is formed with a plurality of second water-permeable holes smaller than the first water-permeable holes, so that a plurality of tapered holes are jointly formed inside the water-permeable layer by the first water-permeable holes and the second water-permeable holes, and
• wherein a portion of the surrounding wall around the water absorbing opening extends toward the water absorbing opening, to thereby form a turned-inward portion, the turned-inward portion being connected to the surface of the water-permeable layer.
