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.
Primaloft Eco® - Primaloft Eco® is comprised of post consumer recycled materials that provide immediate warmth without the bulk. Fine fibers mimic the compressibility of goose down and are breathable, allowing moisture vapor to be transported through the fibers and away from your skin.
Synthetic insulation is measured in grams, so a jacket with a 80g rating simply means that a 1 meter by 1 meter piece of that particular jacket's insulation weighs 80 grams. The higher the rating, the warmer the outerwear.
Recycled Polyester - This product is made from recycled plastic bottles. Approximately 31% of plastic bottles produced in the United States are made from a material called PolyEthylene Terephtalate, "PET" or "PETE." Usually clear or green, the plastic is mostly used for consumer goods such as soda bottles and food jars, but once recycled and processed, it has a wide variety of eco-friendly applications. While recycling is not the end-all, be-all solution for ridding the world of the plastic bag beast, it is a sustainable path for plastic products and takes less energy to produce than traditional polyester. Plus, it means less plastic bottles in landfills, not bad.
