The HECS ® camo suit and baselayer that come packaged together (contains a shirt, pant, and head cover) you should order your size by what you wear in a regular cotton t-shirt in men’s sizes. We researched extensively and have very good success with this method. The pants are more adjustable so the shirt is the most critical. We also offer HECS systems in induvial sizes so you can choose the sizes of the shirt and pants separately. Please see our size chart for more details.
The basic HECS ® system includes a shirt, pants, and head/ face cover. The 3 pieces that make up a system cover about 98% of the body and are enough to see a difference in almost any situation. Accessories will enhance your HECS experience and ensure the ultimate concealment. Accessories include gloves, socks, caps, and multi-rags and are sold separately. We do highly recommend gloves for bird hunters/watchers/photographers as birds see the electrical fields visually and as such are extremely sensitive to uncovered areas of the body. 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. Caps are useful when worn with the multi-rag for top of head coverage but do not significantly add to coverage when used with the full headcover.
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 headcover as the drawstring can sometimes hang up in the machine and damage the product. Also, 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 such as the Scent Crusher system and others of this type may void HECS® warranty.) HECS® has extensively tested the effects of ozone on HECS® fabrics with almost all currently available ozone units. The only system that we have tested that will not harm the HECS® grid over time is the Ozonics brand dry wash system. This is because to our knowledge the Ozonic system is the only one that uses a baffle system to channel the raw ozone around the garment but not actually force it through the fabric. Ozonic also uses a clean air rinse that we believe also helps to alleviate the deterioration of the fabric issue. Also, we have found no evidence of harm to HECS® fabrics by using an ozone generator in the hunting woods (treestands, Blinds ETC.) Bottom line Ozonics brand ozone systems are fine to use with your HECS® suit.
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® camo suit is a light weight, 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. It is most effective when worn as the outer layer.
The HECS® base layer is made from heavier fabric, similar to active wear thermals, making it an excellent option for cool weather locations. It is mid-weight, form-fitting and made to be worn under your clothing. Our base layer fits well under our camo suit.
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 in most situations. Wearing multiple HECS layers will capture the remaining energy emission.
A single HECS® layer will block up to 90% of your bodies electrical output which is enough to drastically change your electrical signature and keep you concealed. While multiple layers does increase the blockage we have not seen significant benefits from multiple HECS® layers in our testing.
The HECS® base material is made from a polyester based fabric and will not shrink under normal conditions and care.
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.
No. While HECS® does contain a significant amount of carbon which does absorb a certain amount of scent (certainly a positive) however, the main purpose of the technology is to block and hold in capacitance the naturally occurring electrical radiation our bodies emit. These fields are proven to be detectable by many animal species. See the HECS® Technology page on the website for more details.
We try to keep all items in stock and ready to ship at all times. Once we receive your order it will ship out either the same business day or the next day depending on when we receive the order. Standard shipping is USPS priority mail however UPS delivery options are also available. In most cases standard shipments within the continental U.S. are received in less than 5 business days. In the rare occurrence that an item is out of stock we will give you the option to back order (your order will put on the “fill first” list) or cancel the order.
HECS® technology can effect some electronic transmission from item such as some FM radio transmission frequencies. HECS® will not affect your cell phone signal or most Bluetooth signals.
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 extreme 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 process to verify to what extent our technology can effect these devices.
That is purely a personal choice. HECStyle camo utilizes a proprietary digital print design that is made to blend into your surroundings on the visual level. HECStyle anywhere was designed to be worn in almost any terrain while HECStyle green was designed specifically for those areas where the foliage tends to be darker and greener. Again since most people use HECS® under other clothing it is a moot point in that situation but for those who use it as an outer layer, the camo is an important consideration.
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 be wearing it.
Different species react differently to our electrical radiation and also the intensity of the fields vary 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 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 distance 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 effect animal reactions. Sometimes the benefits might be subtle but many times they are obvious and indisputable.
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 a 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.
