First Lite Furnace. Crazy thick merino lined with fleece. It’s intensely warm. I can do some light hiking in the bottoms if it’s late season but I have a meltdown if I’m wearing the tops.
I'd rather have a thin baselayer and a fleece midlayer like the Patagonia r1 or a thinner grid fleece. It's much better moisture management that way instead of a heavy wool baselayer.
Patagonia Capilene Thermal weight for cold weather.
I like merino, but only during the summer/early season in a very light weight (sub 150 gram) baselayer. Once it gets cold I have found that there is no such thing as "warm and wet", at least for me. I just get chilled if my baselayer can't dry out. I prefer the quick drying Capilene when the temperature is consistently below freezing throughout the day.
Holy moly you’re right. How in the world are they so bad at inventory? Six months is wild. I get that demand should drop off after hunting season but it’s also the dead of winter. The perfect time to wear a furnace.
