Revamping my hunting clothing and looking to add a high quality puffy for glassing. Hunting mainly in Wyoming so cold and windy, jacket will be worn over a merino base layer and Sitka ambient hoody most of the time, and maybe a jetstream vest if the wind is really ripping. Does anyone have experience with these two jackets? Is the neutrino worth a $60 upgrade? Yes I have looked into the kuiu SDP and SG Grumman but have landed on the rab so please keep the discussion focused
