Geotech 10.000 series: This number tells you how waterproof your garment is. If the fabric is 10k or 10 000 mm, this means you can place a square tube with inner dimensions of 30mm x 30mm over the garment's outer fabric and you could fill it with water to a height of 10 000 mm before water would begin to seep through. The higher this number, the more waterproof the fabric.
Ergonomic preshaping: Articulated patterning for an increased range of motion.
Slim fit: This garment has a fit which is tailored to the body.
Fully taped seams: Fully taped seams are where tape is applied to all the garment seams and sealed using heat. For a garment to be highly waterproof the seams need to be treated in this way so to stop water from getting in through the stitchingholes of the seam.
Vent zips: These are zippers places under the arms or at the legs. They allow hot air to escape from the jacket and cool air to get in. A bit like your own personal air-conditoning.
YKK zipper: This is an A-class zipper.
