On Tuesday, March 15, the Caps will come out for warm-ups looking more like leprechauns than hockey players. That’s because the Caps will be celebrating St. Patrick’s Day with limited-edition green sweaters.

The jerseys feature a subtractive green and white Caps logo. The shoulder features four leaf clovers and a plaid green pattern you’d more likely see on a kilt. There are also gold borders on the shoulder patches and number on the back.

The Capitals are already auctioning these bad boys off. The funds raised will benefit the Anacostia Waterfront Trust, which “supports activities to restore water quality consistent with a watershed strategic vision and plan.” That sounds good to me — especially with the eagle population beginning to rebound around the city. (I love birds.)

Judging by the demand online, the jerseys are popular. Shop.NHL.com is almost sold out of the Caps version already.

Monumental Sports & Entertainment Foundation will host a Go Green Auction featuring limited edition green jerseys worn during the pregame warmups on Amtrak Go Green Night prior to the Capitals game versus the Carolina Hurricanes on Tuesday, March 15. The auction also will feature player-signed pucks with green Caps logos.

The auction will open at noon on Monday, March 14, on Handbid and will conclude at the end of the second intermission during the Caps game on March 15. All proceeds will benefit Anacostia Waterfront Trust with $5,000 being earmarked to Anacostia Watershed Society.

The autographed hockey jerseys and pucks will be on display at the MSE Foundation table located on the main concourse at section 104 of Verizon Center during the Capitals game on March 15. Handbid is a mobile-based bidding app that fans should download on their iPhone and Android devices if they would like to participate in the auction. Fans should ensure their phones or tablets are well charged for the game and those without smart phones may bid on iPads supplied by the Capitals at the MSE Foundation table while the auction is open.

The Anacostia Waterfront Trust’s mission is to work with stakeholders, public and private, to catalyze and support the creation of a world-class waterfront along the Anacostia River. There are three related aspects: to support the District of Columbia and the National Park Service with programming and capital investments to create an outstanding, 21st century public civic space adjacent to the Anacostia; to support activities to restore water quality consistent with a watershed strategic vision and plan; and to support activities to create diverse, healthy, exemplary neighborhoods near the Anacostia.
