Top Rated: OMM Rotor Smock (Primaloft Aerogel Version) (8.5 / 10)
Category: Best Lightweight (Under 400g) Insulated Jacket
An outstanding, high quality, minimalist and genuinely ultralight insulated pull-on with some old fashioned NASA tech thrown in, the OMM Rotor Smock with Cross Core Aerogel is definitely worthy of a special mention. We've been looking for a jacket we could wholeheartedly recommend in this tricky lightweight insulated category. We thought we'd found one in the LIM Barrier, but Haglofs prematurely discontinued it. In our view, Primaloft Cross Core is the future of synthetic insulation and we hope OMM will continue to back the Rotor Smock. We'll happily put our money on a little "solid air" over "blown into baffles to mimic down" and we'll be more than happy to recommend the Rotor Smock as our top pick in the "Lightweight (Under 400g) Insulated Jacket" category.
