What Our Gearhead(R) Experts Are Saying: "This jacket has become my go-to midlayer for big climbs and variable weather. The PrimaLoft(R) Evolve insulation is super breathable, so I don't overheat on the ascent, but it still traps warmth when the wind picks up. I love how it layers cleanly under a shell and how the hood fits perfectly under my helmet-it's built for real mountain missions." When we're charging uphill in unpredictable weather, the Rab Evolute Hooded Jacket keeps us right in that sweet spot between warmth and breathability. Built around PrimaLoft(R) Evolve Active insulation, it manages heat and moisture like a pro, trapping warmth when we stop and letting excess heat escape when we push hard. The soft Motiv(TM) Aero outer fabric wicks away sweat and dries in no time, while its odor control treatment keeps us fresh on multi-day missions. We love the minimalist design-flatlock seams for comfort, an elasticated hood that fits under a helmet, and mesh-lined pockets that double as ventilation. Whether we're ascending icy ridges or moving through mixed alpine terrain, the Evolute proves itself as a dependable core layer for demanding conditions.
