Outdoor Research Helium II ($150)

Outdoor Research Helium II ($150)

At around $150, you start to see technical-performance fabrics that allow for slightly better breathability and lighter weight. Thanks to Pertex Shield fabric, this shell vents sweat, shucks off storms, and weighs a mere 6.4 ounces. Stuff it in a pack and pull it out when rain clouds appear. [$150; outdoorresearch.com]
