holes from stitching are not waterproof

Neoprene is waterproof, but the holes from stitching garment panels together are not waterproof (unless they are sealed). Using aquaseal or seam grip will fill the holes and make them waterproof.
You can also get punctures or tears.
Technically, the pores in neoprene are large enough to let individual water molecules through. Fortunately, water molecules are rarely found in nature by themselves.
