Kohl's offers the Nike Men's Therma Quarter-Zip Top in several colors (Black/Dark Gray pictured) for $33 plus $8.95 for shipping. That's the lowest price we could find by $13 (outside of the mentions below), although we saw it for a buck less in the run up to Black Friday. It's available in select sizes from S to XXL.

Note: Zappos has it for $41.25 with free shipping in select colors/sizes.
