The Neutrino Endurance 600 is hand filled in Derbyshire UK. The zipper uses anti-snag zipper webbing tape which users found effective (and reported no issues with snagging). The Neutrino Endurance 600 uses a mummy taper shape with an angled foot box, strategically giving space where needed while preserving warmth factor. This is also why RAB advertises this product as particularly useful for alpine bivy ledges, lightweight backpacking in inclement weather (or for year round use in tents). The Pertex Endurance outer fabric (also included internally in the hood and neck areas) is extremely durable (being the same fabric that RAB uses on its down jackets) making it even better suited to damp conditions than some other lining fabrics. RAB manages this extremely effectively-providing the user does not have an issue with the height restriction. In RAB bags, those women-specific features translate into shorter length (one size only to a maximum user height of 5’7”), narrower shoulder area and wider hip area. Users found this bag warm in temperatures dipping into the mid 20s.

Additional features, like an extremely generous draft tube and close fitting neck baffle design help eliminate drafts and cold spots, as does its shorter size. It also uses hydrophobic down, treated for faster drying, absorbing less water and greater loft retention (ultimately improving the down performance). The RAB Neutrino Endurance 600 has 800+ down fill and uses a Pertex Quantum lining that allows the down fill to loft at its maximum – and the loft is enough to create a very warm and cozy bag comparable to other bags in this category that have greater loft. It does not compress as small as many of the other bags in the category it is among the largest of bags compared to others in this category.

Loftier bags (and warmer ones) tend to take more effort to compress and the Neutrino Endurance 600 is about average in that respect.
