Rab Neutrino 400 – Editor’s Choice






At £320, the Neutrino 400 is the most expensive bag tested, so the big question is whether it’s worth the extra money. Overall, I think it is: it certainly feels like one of the warmest bags tested, if not the warmest; and the manufacturer’s quoted comfort temperature of 1.5°C is one of the lowest too. Although I think this number is pretty conservative and wouldn’t expect to be uncomfortable down to zero. And at 900g, whilst it’s not a complete featherweight, it’s still a pretty comfortable carry for the warmth it offers. The inner fabric feels soft – almost luxurious – and the shoulder baffle pulls up nice and snug, whether you cinch the hood right up or not. The 400g of 800 fill power European goose down provides the warmth, and is hydrophobic – developed in conjunction with Nikwax – so won’t hold moisture on wet nights or successive cold sleeps. And the Pertex Endurance outer repels water too. The zipper doesn’t snag – a real bugbear of mine when they do – and the draw cords are well-placed and easy to use. It’s a lot of money, but for genuine 3-season comfort, or even alpine use, you’d have to go a long way to find better in this temperature range.
