What Our Gearhead(R) Experts Are Saying:"I've worn the Kinetic 2. 0 on everything from wet ridge scrambles to multi-pitch sport routes where the weather turned mid-climb, and the Proflex laminate stays noticeably breathable even when output is high. The under-helmet hood is a well-executed detail - it seals out weather without blocking peripheral vision on technical terrain. This is the jacket I reach for when I need real waterproof protection without feeling like I'm wearing a trash bag."Storm clouds don't always wait for a good moment. A pitch away from the anchors, halfway up a ridge with nowhere to shelter, deep into a canyon approach with the sky turning dark - these are the situations the Rab Kinetic 2. 0 Jacket was designed for. Built around the Proflex 3-layer laminate, it closes the gap between softshell freedom and hardshell protection in a package light enough to forget until you need it. The Proflex membrane posts a 10,000mm waterproof rating and a 35,000g/m^2 breathability rating, with fully sealed seams and a recycled polyester face fabric that handles the abrasion of technical terrain. The under-helmet hood adjusts via a rear cord without requiring hands off the rock, and a brushed tricot chin guard keeps the zipper from becoming a problem on long days. At 11. 8 ounces, it earns its spot in the pack on every mountain day.
