Janji Rainrunner Rain Jacket

Easily the lightest rain jacket I've ever worn/held. I used it all summer when running on trails that go through a lot of encroaching brush (to help with tick avoidance). It breathes, which helps a lot, and packs down into an absolutely tiny size. I've also used it in the winter while running in heavy rain and it's very waterproof, unlike the water "resistant" jackets I've used previously that leave me soaked through.
