Form,
What is this puffy suit made of?
Any kind of suit that will allow you to wake up in sub zero weather with 20 mile an hour winds, and still be drenched in a 1/4" of sweat, combined with just an SOL bivy is something that I should probably look into.
I have been living in the Rockies my entire life, and spent countless nights outdoors, in all manner of weather, in all seasons, so I am all ears.
