Rab’s Neutrino Pro Jacket is as much of an alpine essential as instant coffee. Unlike instant coffee, the Neutrino Pro is sporting some new updates, namely an anatomical cut that gives you unrestricted range of motion as you travel through the mountains. Rab kept everything we loved about the original Neutrino Pro, like impressive warmth and packability, ethically sourced down fill, and a water-resistant finish to keep you dry when weather rolls in.
