Rated as having a lower comfort limit of -8 deg C, the Rab Neutrino 600 is well-placed to provide warmth. But its performance is enhanced further by using water-resistant down, so even if it does get a little damp from condensation inside the tent the down should maintain its insulating properties better than standard down. The bag is slightly longer than some options in our test so you’re unlikely to squash the warm air out of the bag too easily. The shell is made from Pertex Quantum, which is very breathable and feels comfortable next to the skin. The Rab Neutrino 600 has a zip that extends to the calf area, so you can keep your feet in the end of the bag while venting your legs. This zip has a good baffle and anti-snag strip too. There are elasticated drawcords on the internal shoulder baffle and for the hood. These cords are identical so you could get confused between them, while some bags have different designs for ease of identification. But the cords do work well once you figure out which to use. The stuffsack has a two-stage rolltop compression system and it is designed to be water-resistant too, which is why the stuffsack is heavier than some others. The Rab Neutrino 600 has more features than some other options and that water-resistant down bumps up the price, but I’d say it’s worth the extra cash if you can stretch to it.

Water-resistant down is a luxury but when combined with a great set of features it does make the Rab Neutrino 600 an impressive option if you can stretch your budget. It won Trail’s ‘Best in Test’ accolade.
