Human Energy Concealment Systems

HECS® systems are now lightweight, base layer, and hooded. They come with the shirt, pant, and basic headcover/face cover. Gloves, socks, multi-rag, and ball caps are sold separately. The full system covers about 98% of the body and is enough to see a difference in almost any situation. We do recommend gloves for bird watchers/photographers as birds see the electrical radiation visually and as such are the most affected by our technology. The HECS® socks are a heavyweight over-the-calf type sock that also adds some valuable coverage. HECS® ball caps are extremely lightweight breathable and comfortable and are made from HECS® material but do not add significantly to the coverage if worn in conjunction with the headcover.

The conductive carbon yarn we use to attain the technological advantage is actually woven into the fabric during production. It is a very intricate process that can be accomplished only with special proprietary methods however once the yarn is woven in it is very stable. As such we have seen our garments last over 5 years with normal care and use.

See product information for full warranty details.

The HECS® base material is made from a polyester-based fabric and will not shrink under normal conditions and care.

The HECS® suit is very easy to care for. For terrestrial suits, just machine wash in your favorite detergent. Hang dry for the longest life or dry on low heat for only a few minutes (please note in some dryers HECS® clothing will not be picked up by dryer sensors and will not shut off automatically). It is recommended that you hand wash and hang dry the head cover as the drawstring can sometimes hang up in the machine and damage the product.

You should order the shirt according to what size of regular men's t-shirt you wear. Please refer to the waist size chart for each of the different pants that HECS offers.
