Halo Stack expands the possibilities of Halo through modular heights and versatility. Stacked to 8 inches, it provides elevated support and a substantial surface for steady strength training, mobility, stretching, and recovery. By stacking, Halo Stack gives you greater elevation while maintaining the strong stability, comfort, and simplicity of the original Halo design. Used separately, with dual low profiles you can create new opportunities for movement, allowing you to change angles, increase range of motion, challenge balance, and explore exercises that benefit from additional height. Crafted from high-density EVA foam and finished with Halo’s clean, minimalist aesthetic, Halo Stack is designed to move effortlessly between home workouts, studio sessions, and everyday movement. Dimensions: Includes: Two 4” x 12” diameter Halos PATENT PENDING.
