It must be a new year if an actual, honest to goodness blog post is coming at you, and it must be f'n January b/c there's still an F load of cold a$$ weather out there. As we've had a preponderance of winter of late, I had the opportunity to field test some 4th season gear, notably an ultralight down inner jacket/pants combo from Mont Bell.

Plus I rocked a really macho UL scarf
Sure, I nabbed these items pre-Wonderland due to the misguided notion that I was overly cold-sensitive, and not just previously enjoying several broken ribs. (It's every man for himself out there, after all). But hey, no worries: you can never have too much gear!
Though designed to be utilized primarily as an insulating layer, I found that both the Mont Bell UL Down Inner Jacket and matching UL Down Inner Pants were remarkably wind resistant on their own sans shell layer. Both are incredibly light, run a little big, and are truly excellent insulators.

I "performed" a good half dozen field tests with and without a shell layer, in both inclement and clear weather, to and from anywhere I needed to go while stuck for several weeks under 1.5+ feet of snow. FY, Snow Miser!
What an assjack. Regardless, I couldn't have been warmer and more comfortable rocking the Mont Bell combo in 20 degree weather usually only rocking Ex Officios and an OXT T shirt as a base layer, gloves, mitt shells, and Sorels over an average distance of ~5 miles and an average temp of ~25 degrees F. The fact that both run a little large provided not only for excellent mobility, but for the use of thicker capilene base layers on several occassions, which actually helped with sweat mitigation - these feels keep you very warm. In wet snow conditions I was comfortable wearing a Gore-Tex shell layer over both very easily as the down fill design is highly maleable and strong, and I would imagine being warm in sub-zero conditions using the Mont Bell jacket and pants as a solitary insulating layer.
In conclusion, I give the Mont Bell UL Down Inner Jacket and Pants my highest possible recommendation as an extremely light, high performance 3 season insulation layer.
