Ever since, we've spent most of our waking hours looking for an excuse to get excited about zippers once again, because we literally have nothing better to do. Literally. Columbia Sportswear must have noticed, because they've come up with a new type of zipper called the LIGHTRAIL ZIPPER, which is not capitalized like that but we're just so incredibly excited that we can't help it.

What's the exciting bit about the LightRail zipper? There are all kinds of things: it's so thin that the seam is nearly invisible when closed, it's soft and flexible, and it closes so securely that it's waterproof.
