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.
Stretch Boot Gaiter with Lace Hook - Helps prevent snow from going where you don't want it.
Continuous Crotch Vent - The vent on these pants is a bit different from your standard snow pant's vent, instead of two separate vents on each leg this vent gives you control over whether you open the vent a bit, or entirely, which allows for rapid cooling.
