Rab Neutrino Pro Down Jacket - Men\'s The Neutrino Pro Jacket has been a favourite of mountaineers for the last twenty years. Updated with recycled materials and a new arm baffle design, the new Neutrino Pro now has greater mobility and a lighter footprint. Perfect for climbing in winter conditions, this alpine down jacket is filled with 800FP, RDS certified goose down. This ultra-high lofting down is extremely insulative, even in freezing temperatures. The Neutrino Pro uses a recycled, wind and weather resistant Pertex® Quantum Pro outer, offering refuge from blizzards, withstanding snow, and spindrift. The new anatomically engineered twisted arm baffles improve arm pre-curve, enabling complete freedom of movement. Designed specifically with the demands of winter climbing in mind, whether you’re questing up frozen waterfall or belaying from an exposed ledge, the Neutrino Pro offers unhindered movement for proficient climbing. Incredibly lightweight and packable for such a warm jacket, the Neutrino Pro can be compressed into its stuff sack and stored in your pack. It has a fully adjustable, helmet compatible, down filled hood and a tough, two-way YKK® VISLON® front zip for ease of use with a harness. Designed for durability in rugged terrain, the shoulders and upper sleeves have been strengthened with Ripstop reinforcements. A true staple for alpinists, the new Neutrino Pro is ultra-warm, hardwearing, and honed for vertical adventures.

By combining a tightly woven face fabric with a microporous coating, Pertex® Quantum Pro delivers weather resistance whilst remaining lightweight, soft, and breathable. It’s ideal for use in cold or damp environments. Nikwax® Hydrophobic Down Finish - Down is naturally breathable, which makes it very comfortable to wear, but this comes with a drawback – it can absorb moisture. This moisture can overload the fibres, or cause them to stick together, stripping the down of its insulative properties. To mitigate this effect, we apply a Nikwax water repellent “hydrophobic” treatment to the down. This treatment significantly improves the performance of the down by preventing the clusters from absorbing moisture and helping it to retain its loft. In the event that the down does become waterlogged, the treatment significantly decreases the time it takes the down to dry and its loft to recover. Responsible Down Standard (RDS) Certified - The Responsible Down Standard (RDS) aims to ensure that down and feathers come from animals that have not been subjected to any unnecessary harm.
