A favourite amongst Rab sponsored athletes, the Neutrino Endurance Jacket has become the benchmark technical down jacket for modern mountaineering and light-weight ascents. The light-weight nature of the Pertex fabrics gives the Neutrino Endurance excellent packability, without compromising on technical features or insulation weight. High lofting is guaranteed by 225g (Large) of the highest quality 800FP Hydrophobic Down. Key technical features include a down-filled helmet-compatible hood with a wired peak for extra protection. The Neutrino Endurance Jacket also features a 2-way YKK AquaGuard front zip and 2 YKK AquaGuard zipped hand pockets, which dramatically increases the water-resistance and durability of the jacket, making it ideal for UK and alpine winter conditions.
