PETTER NYQUIST/SPLASH NEWS
Alexander Skarsgård can't keep his clothes on, even in sub-zero temperatures!
In a new recently released photo from his South Pole charity trek back in December, the super-sexy True Blood hunk strips down again to celebrate his team's journey across Antarctica for Walking With the Wounded.
In the photo, which was taken on Dec. 13, 2013, Skarsgård stands in the snow in only tiny black briefs, boots and a hat (check out those abs and pecs!). On his face he wears a fake yellow beard and sunglasses.
