Just because there are rain clouds overhead doesn't mean you need to search for cover. Instead, grab the Rab Men's Kinetic Ultra Jacket and head for the hills. Using Rab's highly-breathable Proflex 3-layer fabric, this rain jacket gives you the waterproof protection you need for drizzles and downpours alike, while still offering enough ventilation to keep you cool underneath. A roll-away hood, extended cuffs, and storm flap offer additional protection, while the built-in vents let you dump excess heat for hill climbs. Weighing under ten ounces, the Kinetic Ultra won't slow you down and barely takes up any room in your pack, making this a trail running jacket you won't hesitate to bring along on any adventure.
