Lisnagarvey beat Banbridge in Sunday's final to clinch the first Champions Trophy title.
The Hillsborough club won the regular season with plenty to spare, making them hot favourites for the title.
They duly swept into the final with a 3-1 success against Pembroke in Saturday's semi-final and repeated the scoreline at Havelock Park on Sunday.
In the women's final, Anna O'Flanagan netted twice as Dublin side Hermes beat Ulster's Pegasus 3-1.
Banbridge had reached the men's final courtesy of a shoot-out win over Monkstown, but found the final hurdle too high for a fourth successive campaign.
Michael Watt gave Garvey the lead in the 11th minute and Bann replied when Stevie Dowds converted from a penalty stroke.
Garvey, though, quickly restored their advantage when Daniel Buser scored into the roof of the net.
The third came when a penalty corner fell for Matthew Nelson to dink over Banbridge keeper Gareth Lennox from close range before half-time.
Anna O'Flanagan and Emma Gray inspired Hermes to their first All-Ireland crown since 2008.
They went into a seventh-minute lead when O'Flanagan beat keeper Sammy-Jo Greer from the left edge of the circle.
Only a couple of minutes later, the striker was through again to unleash another cracking shot for 2-0.
Taite Doherty pulled one back but Pegasus suffered a setback when Steph Thompson got a yellow for a foul on Naomi Carroll.
It helped Hermes to completely control the final 10 minutes and their clinching goal came when Nikki Evans deflected in a shot by Sinead Loughran.
The Dubliners closed out the win, giving them their ninth All-Ireland trophy, following four wins in the Irish Senior Cup and four in the old Club Championships.
