Columbia introduced its new waterproof LightRail Zipper technology when they designed and produced the outfits for those three nations. The seams almost completely disappear when sealed shut into garment. Plus, they are more flexible, lighter, slimmer, and easier to zip than traditional waterproof zippers. These new zippers will probably be available to the consumers by the end of this year.
