GORE-TEX® - GORE-TEX fabric is incredibly durable, waterproof, breathable, and totally windproof. A single square inch of this fabric contains 9 billion microscopic pores—each 20,000 times smaller than a raindrop, but 700 times larger than a molecule of water vapor. Water can’t pass through the fabric, yet perspiration escapes with ease. You’ll find this next level molecular construction on all GORE-TEX fabrics.
Fully Taped - Having outerwear with fully taped seams means that on the inside of the jacket all the seams are covered in tape to provide the most effective waterproofing. It can be considered a key feature if you live in a wet climate or are planning on wearing the jacket during heavy rains. The downside is that due to the full taping there is less breathability than you'd experience with critically taped seams.
