Bears' Barkley wears wet suit under uniform vs. Packers

On an afternoon that is projected to challenge the record for coldest game in Chicago Bears history, quarterback Matt Barkley has an interesting strategy for staying warm.

Barkley is wearing a wet suit under his uniform Sunday, according to NFL.com's Max Meyer.

You know, like scuba divers wear. And also triathletes, who swim in cold water.

Apparently, the tip was passed down to Barkley from Tom Brady via Matt Cassel.

The advantage a wet suit provides is that it remains flexible in cold weather while insulating the wearer.
