Skull & Co. Convex Thumb Grips Set: Skin, CQC Joystick Cap Analog Stick Cover for Xbox [XSX/XB1] Controller and ROG Xbox Ally- Black, 2 Pairs (4pcs)

You’re going to want ones designed for the Xbox. Odin 2 has large, concave. The ones I linked have extra material in the middle so you don’t get a little squishy bubble effect. I used these for a bit but ended up cutting the rubber off the odin3 grip and glued on ps5 replacement caps. https://a.co/d/01iE4uEU Edit: you can get either the concave or convex options from that amazon link. But you want grips for Xbox series X controller.
