The Patagonia Boulder Fork Rain Jacket is built for the hikes where weather is a variable, not a plan. A 3-layer H2No Performance Standard shell blocks rain and wind without the bulk of a heavier technical layer, and it packs down small enough to ride in a hip-belt pocket, so it goes on every outing rather than only the ones where rain seems likely. What Our Gearhead(R) Experts Are Saying:"This is the jacket I stuff into a daypack and forget about until the sky changes. The fully sealed seams and H2No laminate mean I'm not scrambling for cover when a trail shower rolls in."
