The Pentagon™ Heavy-Duty offers a massive 41.5 square feet of interior space. Its pentagon shape creates a footprint 70% larger than a comparable 4-sided hub blind. The Pentagon™ Heavy-Duty is constructed from tightly woven 600-denier waterproof polyester fabric for increased durability. The fabric is brushed to create a low-gloss exterior for blending in. The windows drop down for easy sightlines while sitting, and the center windows have pass-through holes to provide multiple shooting options.
