How your waterproofs are made tells you what they're best for. A 2-layer construction has a separate lining and is a great all-rounder for day hikes and general use. If you're a runner or cyclist needing something light and packable, a 2.5-layer shell is what you're looking for. For those heading into serious mountain weather, a 3-layer jacket offers top-tier protection and strength. The technology inside, whether it's GORE-TEX, Pertex Shield, or eVent, is what does the heavy lifting to keep you dry and comfortable.
Whether you need a waterproof jacket for the trail or waterproof trousers for your commute, choosing the right technical hardshell means you can forget about the forecast and focus on your day.
