This year, the Colts are letting fans decide the design for their t-shirt to benefit breast cancer research.

As you've no doubt noticed over the past several seasons, the NFL has observed October as Breast Cancer Awareness Month by having players and coaches wear special gear featuring pink highlights. Teams also allow fans to get in on the action by producing and selling team apparel featuring the signature color of Breast Cancer Awareness, with a portion of the proceeds being donated to help the fight against breast cancer.

Below are the four designs created by the Indianapolis Colts Women's Organization, the group that spearheads the fundraising effort. To cast your vote, simply click the "Vote" button next to the style you like the best (I'm partial to number two, personally).

Each year, we design and sell t-shirts during the month of October (Breast Cancer Awareness Month) to raise money ... in Indianapolis Colts Polls on LockerDome

To date, the Organization has donated an average of $20,000 a year to the IU Simon Cancer Center through t-shirt sales. Voting continues until May 19th.
