SKI PANTS BUYING GUIDE
Seam taping prevents moisture from seeping through the seams of your ski pants. There are two common types of seam taping:
Critical taping means that only the seams that are normally exposed to moisture are taped. This is the least waterproof option but if you're not expecting wet weather, critical taping should be enough to keep you dry.
Fully-taped ski pants have every seam taped, on the outside and inside of the seam, for ultimate waterproof protection even in extreme weather conditions.
