Training Weight Vests are designed to hold one plate in the front and one plate in the back pocket. Both pockets are compatible with our 10lb, 20lb, and 30lb Rucker plates only. The 45lb and GR1 plates will not fit.
However, we have found that most other brands of weight plates will fit, but for reference the largest plate that will fit in our vest pockets is 9" x 11.5" x 1.38".
