If you were a contestant this season would you go with the latest cold weather technical gear or tried and true parkas?

Just curious what others are thinking. Some new cold weather gear is tested and rated for extremely cold temps, I guess it depends on what contestants can afford.

The parkas are tried and true, obviously have been working for thousands of years, I feel like I would miss convenient pockets and possibly waterproof capabilities?

Callie does look super warm and cozy. if you had 1 mil on the line what would you choose?
