Key Details
What Omni-Tech Waterproofing Actually Means
Columbia's Omni-Tech is a waterproof-breathable membrane, not just a surface DWR coating. A DWR coating repels light rain but saturates when wet enough. A membrane like Omni-Tech physically blocks water penetration through the fabric while allowing moisture vapor to escape from the inside. Seam sealing closes the needle holes from stitching, which is where most rain jackets leak first.
With 4,241 reviews at 4.5 stars, buyer confidence in the Glennaker Lake II is real and consistent. The packable design adds utility: the jacket packs into a small stuff pocket when dry, making it practical to carry in a bag every day rather than leaving it at home because it seems bulky.
