Tackla has always, in my opinion, made the best pants and girdles. They have a couple of models available on different sites:
The classic 4500 girdle (I used one for years and liked it much better than my Bauer girdle): https://www.icewarehouse.com/Tackla_Ice_Hockey_Girdles/catpage-TACKLAGIRDL.html
The new Breezer girdle (which I've heard is incredible): https://www.hockeymonkey.com/tackla-hockey-girdle-breezer-sr.html
Good luck!
