A true staple for alpinists, the new Neutrino Pro is ultra-warm, hardwearing, and honed for vertical adventures. Updated with a new arm baffle design and 100 recycled fabric, the new. Designed for durability in rugged terrain, the shoulders and upper sleeves have been strengthened with Ripstop reinforcements. The Neutrino Pro Jacket has been a favourite of mountaineers for the last twenty years. 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 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. The new anatomically engineered twisted arm baffles improve arm pre-curve, enabling complete freedom of movement. The Neutrino Pro uses a 100% recycled, wind and weather resistant Pertex® Quantum Pro outer, offering refuge from blizzards, withstanding snow, and spindrift. This ultra-high lofting down is extremely insulative, even in freezing temperatures. Perfect for climbing in winter conditions, this alpine down jacket is filled with 800FP goose down. Updated with a new arm baffle design and 100% recycled fabric, the new Neutrino Pro now has greater mobility and a lighter footprint. Star rating: 4.The Neutrino Pro Jacket has been a favourite of mountaineers for the last twenty years. The only drawbacks are the cost – though some comparable bags cost even more – and that it’s only available in one length, suitable according to Rab, for people up to 185cms tall. The Neutrino 800 is an ideal winter backpacking bag, especially if you’re a cold sleeper (I suspect I’d be too warm in it in above zero temperatures). Its weather-protective outer shell and premium water-resistant down insulation equip it for whatever Mother Nature throws at it. The down is traceable under the European Down & Feather Association Codex, which means it’s either the by-product of geese slaughtered for food or is harvested during moulting and not from live-plucked birds. The Rab Mens Neutrino Pro Jacket is built to provide maximum warmth and protection for expeditions, in alpine conditions, or simply against extreme cold. Whilst the shell of the bag is made in China it’s hand-filled in Rab’s factory in Derbyshire (one of the reasons for the high price). The down is also treated with a Nikwax product to make it hydrophobic so it will resist a fair amount of moisture, as I found when the frost round the hood melted, though it’s not waterproof. The very high fill power down is held in chambers with trapezoidal baffles – internal walls angled towards each other. A technical mountain jacket suitable for winter alpine conditions up to 4000m, this jacket uses weather-resistant Pertex Quantum Pro outer fabric that deals with spindrift and snow. It has a thin Pertex Quantum shell that allows the down to loft fully and all the usual features – shaped foot, hood, neck baffle, thick baffle behind the zip. The Mens Neutrino Pro Jacket from Rab is a lightweight down-filled mountain jacket with stitch-through construction and a Pertex Quantum Pro outer. This really is a very warm bag for the weight. I’d been waiting for some really cold weather to try it in and now that it had arrived I was impressed. The sleeping bag that was keeping me so warm was Rab’s Neutrino 800, a lightweight bag with phenomenal loft.

In fact I felt very comfortable and snug and soon feel back to sleep, only waking again at dawn, when the temperature was a milder -6☌. The rest of me was pretty warm too, clad only in thin base layers.

I was lying with my head in the open door of the tent. I stuck a hand out of the sleeping bag, displacing frost from round the hood, and grabbed my extremely cold watch. The moonlight shining on my face woke me. A freezing night on the Moine Mhor shows Chris Townsend just how warm the Rab Neutrino 800 sleeping bag is
