The Pentagon™ Heavy-Duty offers a huge interior of 41.5 square feet. The pentagon shape creates a 70% bigger footprint than a comparable 4-sided hub blind. The Pentagon™ Heavy-Duty is constructed from a tightly-woven 600 denier, waterproof polyester fabric for added durability. The fabric is brushed to create a low sheen exterior to make it blend in. The windows dip low for easy sight lines while seated and the center windows have shoot-through holes to provide multiple shooting options.
