The women’s Neutrino Endurance has become a modern classic & a benchmark for lightweight performance amongst down mountaineering jackets. Fully featured & very warm with durable protection against the elements & minimal weight & pack size; the Neutrino is one of those jackets that is capable of anything from UK winter walking & mountaineering to winter Alpine ascents. Stuffed with 200g of superior European Hydrophobic Goose Down with a very impressive 800 fill power, & protected by lightweight but tough ripstop 30D Pertex Endurance which offers protection from windblown snow & light rain without adding bulk. Despite the high water resistance of the face fabric the Neutrino Endurance is not totally waterproof, so always pack a shell if, & when, the weather turns really nasty. Rab is now using Hydrophobic down in all their down jackets, basically each & every cluster of down is treated with Nikwax products to make them perform better in damp conditions. Although Hydrophobic down is not waterproof it dries much faster, absorbs less water & retains loft far better than untreated down. Despite the low overall weight of 593g there is still the usual Rab attention to detail, a proper wired peak to the down-filled hood, water resistant zippers on the front & the pockets, making this a really well specified alpine jacket. 30D Pertex Endurance shell Pertex Quantum inner Stitch-through baffle construction 200g of 800 fill power superior quality Hydrophobic European Goose Down Down filled helmet compatible hood with wired peak Two external zipped pockets One internal security pocket Water resistant zippers to outer pockets Two-way water resistant YKK front zip Internal down baffle Velcro adjustable cuffs & hem drawcord Supplied with stuff sac
