We had to depart in the vans at 4 AM to get to the lek with enough time to setup the blinds. The blinds had unzipped openings to look through (i.e. the openings were an exposure to the air temp/wind). The morning temp bottomed out at 58 F so relatively warm all things considered, and early in the morning, there was little wind. The wind picked up over the course of the morning, though. Here’s what I wore and was perfectly comfortable…
- knit hat
- thin buff (the one I got from CMWWRC)
- finger-less/convertible mitten gloves
- parka
- light nylon base layer
- tee shirt
- cotton leggings
- Arctic muck boots
- thermal electric socks
In this instance, I could have gotten by without the heated socks, but if it was any colder they probably would have come in handy. I never did turn them on, so maybe you could swap them out for wool socks. I wanted to be prepared for sitting still for a long time with adjustable heat options, while sitting in a spot where too much wiggling was both impractical and potentially disruptive. So, be prepared for chilly conditions when you are camped out not moving!
