Seattle Times features Flex

If you prefer down insulation, or you want something that will keep you warm even when the temperatures drop into the negatives, consider the new Sierra Designs Flex down jacket. This is the first real innovation in the puffy down jacket in years. Sierra Designs incorporated the flex technology used in their high-end sleeping bags to make this insulated jacket for active recreationalists.
The Flex design allows the body of the jacket to expand by as much as 4 inches as you twist, turn and stretch while skiing, climbing or paragliding.  That means the jacket doesn't ride up or pinch when you move.
