HECS Stealthscreen Base Layer 3-PIECE SUIT INCLUDES  one long sleeved top with quarter-zip neck, one pair of bottoms which features a HECS branded elastic waistband and a usable fly, and one lightweight head cover in Mossy Oak Country. 100% machine washable, tumble dry. COMBINE COMFORT WITH CONCEALMENT  An Electrically conductive carbon grid is woven into the high-performance wicking base layer fabric to ensure you remain as undetectable as possible without sacrificing any comfort for extended periods of time. SCIENTIFICALLY PROVEN  EMF blocking garments have been studied extensively for years and its been successfully concluded that HECS Stealthscreen material makes a human less detectable and allows hunters to get 69-75% closer to an animal.

(see photos for size chart) If your heart is beating and your muscles are moving, you are producing an electrical energy field that animals are capable of detecting. HECS is the revolutionary and only technology available that blocks your energy, preventing those creatures from sensing your presence. The effectiveness of the energy-blocking mesh hinges on the size of the grid relative to the wavelength of the electrical energy itself. The HECS grid, through exhaustive testing, was developed specifically to block the wavelength of the human energy signal. <ul class="a-unordered-list a-vertical"> A common, everyday example of a grid that blocks waves can be found in the door of your microwave oven. The small mesh in the microwave door is properly sized to block microwaves for your safety, just like the somewhat larger grid in a HECS garment is designed to block human electrical energy waves. The size of the HECS grid works to effectively block human electrical energy waves, just as the much smaller grid in the door of your microwave works to block microwaves. The conductive carbon fiber grid that serves to block the electrical energy signal that you are constantly giving off is integrated into the fabric that is then used to build HECS garments. The fiber itself is completely flexible, so you wont even notice it is there. The fabric, and the garments it is used to make are lightweight, breathable, durable and machine washable. Because the carbon fiber is woven into the fabric, it will not wash out or wear out.
