3-in-1 Soft Plyo Box

The high-density inner foam core provides structure to resist landing surface deterioration and enough weight for box stability. The outer foam layer is softer and delivers an edge that will not injure your shins if you miss a jump.

Precise manufacturing process yields a perfectly square box with a tight cover. High-strength velcro connects your plyo box seams together and doesn't break like traditional zippers.

Plyo boxes feature anti-slip landing pads that keep your feet firmly in place even with sweat on the surface.

Stackable Plyo Box

Build explosiveness and jump height by stacking plyo boxes or use separately to create a plyometric training circuit.

Made with form following function - each top facing surface is designed to help stability when jumping. The plyo box is made from a soft, ultra-dense foam center and slightly less dense outer core, reducing the hardness of edges; and it also has a 76x92cm landing area, providing space and stability for jumps.

They are covered with reinforced vinyal on all four faces, and the top has an anti-slip surface heat welded on for enhanced grip, less wrinkles and less slippage from sweat. Velcro and tabs are used to keep stacked boxes secure, but can also be easily tucked out of the way for quick customization.
