If you can deal with the GB colors this is the cheapest I have found the full suit. Note: the suit does not say GB or Green Bay its just the color.
$269.00 for the jacket and bib. For those not familiar with the suit you will float if you fall through the ice. They claim it will actually float 2 people but i haven't seen any videos of 2 people floating on 1 suit.
