Our standard Ruck Plate Carrier is compatible with the 10LB, Standard 20LB or 30LB. Keep in mind, the Ruck Plate Carriers can only hold one 20 or 30lb plate at a time. You can fit a 10lb and 20lb standard plate at the same time, however.
The Long Ruck Plate Carrier is compatible with the 45lb plate but any of our other plates will fit too. However, there will be some remaining space in the pocket so you will want to buffer any remaining space with a small towel of something like that.
