Wanted to upgrade my gear this year and the Solitude set from Frist Lite was perfect. It is warm enough that it does not require much layering of other garments to keep warm and results in much more maneuverability by not having four or five layers on. The zippers on the bibs and jacket to vent out heat are clutch and being able to access the internal muff on the bibs as well as vent through the same pockets is a very clever idea. 10/10 would recommend the solitude jacket and bib combo.
