HECS

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.

That is purely a personal choice. Again since most people use HECS® under other clothing, it is a moot point for that situation. For those who use it as an outer layer, the camo is an important consideration.

Our base layer and our camo suit both start with the same energy-blocking HECS® technology and are created differently to accommodate different climates. The HECS® base layer is made from heavier fabric, similar to activewear thermals, making it an excellent option for cool weather locations. It is mid-weight, form-fitting, and made to be worn under your clothing. The HECS® camo suit is a lightweight, loose-fitting layer constructed from breathable material suitable for warmer climates. It works well as an outer shell for layering or the primary article of camouflage clothing you wear.

HECS® technology can affect some electronic transmission from items such as some FM radio transmission frequencies. HECS® will not affect your cell phone signal or most Bluetooth signals.

No. While HECS® does contain a significant amount of carbon which does absorb a certain amount of scent (certainly a positive) the main purpose of the technology is to block and hold in capacitance the naturally occurring electrical radiation our body emits. These fields are proven to be detectable by many animal species. See the HECS® Technology page on the website for more details.

A single HECS® layer will block up to 90% of your body's electrical output which is enough to drastically change your electrical signature and keep you concealed. While multiple layers do increase the blockage we have not seen significant benefits from multiple HECS® layers in our testing.

Yes! HECS® is made to be worn in conjunction with other garments. In fact, most people use their standard HECS® suit as an underlayer most of the time. Of course, the base layer is designed to be used exclusively as an underlayer. HECS® technology works no matter what layer you use it in. As long as you have the entire suit on you will see the benefit under or over other clothing or all by itself — doesn’t matter.

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.

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 can use any of your favorite scent sprays, insect repellent, and the like without damage to the suit.

Use extreme caution when using ozone dry wash systems with your HECS® gear. Raw ozone in heavy concentration is extremely destructive to HECS® carbon yarn (Please note: Exposure of HECS® fabrics to Ozone dry wash systems which put raw ozone directly on HECS® fabrics may void the HECS® warranty.) HECS® has extensively tested the effects of ozone on HECS® fabrics with almost all currently available ozone units. Also, we have found no evidence of harm to HECS®fabrics by using an ozone generator in the hunting woods (treestands, Blinds ETC.)

Size

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.

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

The short answer is yes if you want the full benefit of the technology. Certainly having any HECS® on will reduce the electrical emission and be beneficial, but to see the full effect of HECS® in the field we strongly recommend that everyone is wearing it.

Different species react differently to our electrical radiation and also the intensity of the fields varies greatly from one person to another. In general terms, birds are the most sensitive of the land animals to naturally occurring EM fields emitted from living beings. We believe they can see these fields visually and as such, they can pick up on them from a great distance. The HECS® effect on most common animals like deer and many other mammals generally can be observed at distances under 40 yards. However, we have seen some instances where the effect is apparent at much further distances up to 200 to 300 yards or more. Canines, cats, and bears are very sensitive to EM fields as well and we have seen effects at distances over 200 yards with these animals. A recent discovery found that canines actually have the highly electrically conductive molecule Cryptochrome in their eyes. This is the same molecule that is believed to be responsible for electromagnetic sensitivity in birds. As more and more scientific discoveries are made in this field, the more HECS® technology is being confirmed. There are other factors such as atmospheric conditions and the age and experience of the individual animal that also can affect animal reactions. Sometimes the benefits might be subtle but many times they are obvious and indisputable.

While it is indisputable that our electronic devices do emit electronic energy, it is very important to realize that man-made electronics in any form have only been around for a very short time on an evolutionary level. What we emit as living beings is an extremely low-frequency field and is very different from energy fields emitted by common electronics. While there is some debate on whether or not animals can sense these wavelengths of energy, we can say with certainty that they have not had enough evolutionary time to develop a natural defense mechanism to those fields. Living beings have been emitting these fields for eons and thus animals, birds, and fish have developed natural sensitivity to these fields and instinctively react to them. With that said, however, we have heard many reports of HECS® material being used as covers to make game cameras less detectable. This is certainly a feasible concept and ongoing research is in the process to verify to what extent our technology can affect these devices.

While HECS® will not claim to prevent animals from becoming aggressive or attacking and causing harm, reducing our electrical signature can reduce the chances of aggressive encounters with some animals. We have often seen reduced aggressive behavior from dogs, bears, and other large “predatory” animals. Many times they act more confused than aggressive when they encounter a person wearing HECS® technology. Sharks are well known to sense electrical radiation from their prey during attacks so it stands to reason that eliminating those fields could naturally reduce the chances of a negative shark encounter. IMPORTANT! Animals and fish (such as sharks) are very unpredictable and there are many factors that can trigger aggression. HECS® will not keep you from being attacked! It is always the responsibility of the individual to exercise caution and common sense when in areas where dangerous animals are present. HECS® technology is nothing more than a tool to help reduce the chances of aggressive animal behavior. Realize and accept that it is still completely possible to be attacked by an animal or fish while wearing HECS® technology and HECS® assumes no responsibility for any individual who is harmed while wearing our technology.
