You'll have to look closely at Columbia Sportswear's new waterproof zipper technology to find the seam. The whole thing is engineered to be almost invisible when shut.

The company was contracted to design and produce the outfits for three nations - U.S., Canada and Russia. They introduce its new waterproof Lightrail Zipper technology they've been developing for the past few years. They are lighter, slimmer, more flexible and easier to zip than traditional waterproof zippers.

The Lightrail Zippers are bonded to jackets and other garments using laser-cut fabric that works in a similar fashion to adhesive seam tape.
