Waterproof vs. water-resistant

• Waterproof/breathable: keeps out hard, driving rain while also being breathable
• Waterproof/nonbreathable: a slicker or poncho—inexpensive but traps heat
• Water-resistant: can handle light to moderate rain, breathable but permeable

Windproof vs. wind-resistant

• Waterproof jackets are also windproof, do not let wind pass through fibers
• Wind-resistant jackets are lighterweight but won't handle a squall

Hard shell vs. soft shell

• Hard shell: the most protection, less breathability, not insulated
• Soft shell: stretchy and breathable, best for high-exertion, typically water-resistant, not -proof

Rainwear layers

• 2-layer: quietest, midweight, durable moderately priced
• 2.5-layer: lightweight, good protection, lowest priced
• 3-layer: best protection, best protection and breathability, highest price
