The good-natured Super Bowl rivalry between Captain America star Chris Evans and Guardians of the Galaxy star Chris Pratt has moved beyond a charity bet to inspire a charity T-shirt.

As CBR noted last week, Boston native Evans and Seattle resident Pratt dug in for their own Civil War:  If New England wins Super Bowl XLIX, Pratt will don a Patriots jersey and make an appearance at Christopher's Haven in Boston, which provides a home away from home for young cancer patients and their families while they undergo cancer treatments at nearby hospitals. but if the Seahawks win, Evans will dress as Captain America and visit Seattle Children's Hospital while carrying a 12th Man flag.

Now TeeFury is getting in on the action with a "Chris Vs. Chris" shirt, featuring the familiar helmets of "The Outlaw" and "The Patriot." Proceeds from sales benefit Christopher's haven and Seattle Children's Hospital. The shirts are available for purchase through Feb. 10.
