Gailltir are Munster intermediate camogie champions for the third year in a row.
The blue and navy defeated Thurles Sarsfields 1-11 to 0-6 in the delayed 2020 decider at a freezing cold Mallow.
The Waterford champions trailed 3-2 at half time after playing against the breeze. Captain Margo Heffernan was ruled out of the game with a broken hand.
Gailltir took a grip in the third quarter. Goalkeeper Ciara Jackman sent over a huge free from her own 65 before Annie Fitzgerald and Roisin Flood put them in front. Alannah O'Sullivan found net on 40 minutes to leave them 1-7 to 0-5 ahead at the second water break.
Late points from Aoife and Annie Fitzgerald wrapped up the win. Jackman capped a superb display with a diving save from Ciara Cummins.
