Our Verdict
The Rab Nebula Pro Insulated Jacket is durable for demanding winter pursuits, mountaineering and winter hikes. Using PrimaLoft® Silver RISE insulation, the coat offers impressive warmth with synthetic fibres that mimic down's loftiness, creating excellent heat retention even in damp conditions. The robust construction and warmth-to-weight ratio make it a reliable choice for those needing dependable insulation in unpredictable weather.
The jacket’s 30D Recycled Pertex® Quantum Pro outer fabric, treated with a fluorocarbon-free DWR, provides solid water resistance, ideal for snow-laden trails and misty climbs. The helmet-compatible hood with volume adjustment and a stiffened peak enhance coverage on blustery days, while the fleece-lined chin guard and insulated zip baffle help lock in warmth. Practical details like the dual-sided hem adjustment and elasticated cuffs allow for easy use with gloves, keeping warmth in and cold out.
The thoughtful pocket layout includes two concealed hand pockets, an inner security chest pocket, and an integrated stuff pocket with a harness attachment loop. While the jacket may feel bulkier on fast-paced routes, it performs excellently in cold, damp settings where warmth and resilience are top priorities.
