The night you first put on a one piece freezer suit is the night you say to yourself,
"why did I waste all that time over the years bothering to put on countless layers
of clothing". Often you can get away with just a T-shirt and shorts underneath.
Having observed for periods from dusk to dawn on every clear night for months at
a time with no indoor refuge or shelter available at the observing site, the freezer suits
kept us operating at maximum efficiency all night long without us ever feeling cold.
