Due to a recent business conflict we can no longer supply a discount code for HHV products as promised. I sincerely apologize for this change; however, we have reached an irreconcilable point and must cut ties with HHV. That said, the VSO affiliates page has many others for VSO viewers to take advantage of. Thank you.
Eskimo parkas made from seal skin are better than synthetics for retaining heat and blocking thermal leakage or at least they were according to one video I watched on the subject. So leather, inuslated and non insulated might be a good materials to check too. P.S. They're pricey so they're not a option for most people.
I've been there. Made a stealthy hat over month, until I could place it in most places around me and friends would not find it. So I thought, hey thanks to the shape, it should work well for nightvision. My first test looked promising. Then I tried to impress a friend. Put it in his garden and asked him to find it. He just took seconds to find it, because he ran around with IR on, like nobodys business.
@@kevinm.n.5158 I'm probably old enough to be your grandfather. But for certain, you're the idiot here. But what I did say was covering that synthetic material with local vegetation will cover up all that shiny. The shiny only matters if it is all out there by itself. You know what they say when you assume? the first part definitely applies to you.
If you can see it during the day, then night vision will allow you to see it at night. That's the purpose of night vision. it's not some magic reveal. If someone is hidden from your sight in the day, it is likely they will be hidden from you using night vision. Thermal overcomes that limitation by revealing heat signatures in an area. So you need clothing that reflect the ambient temperature and not your body temp.
Speaking of UV enhancers old timers like myself may remember when the Army first issued the UCP / ACU failure en masse, we had a list of approved / recommended detergents to use as well as proper laundry procedures. We were no longer supposed to starch our uniforms as well. All of these things destroyed the UV protection supposedly embedded in the fabric of the uniforms
Hey Folks, this audience consistently drives me to do things. Thank you. Please share this video around and hopefully we can make it popular enough for a follow up
I Love this whole Approach❤🇺🇸 But to be sure, you should take a camo Uniform and dunk it in mud. Just to see if it reflects as much Light as a clean Jacket.
I am a little late but i was in the industrial laundry and dry cleaning business for a very long time. Optical brighteners sometimes can be mitigated with glacial acetic acid in rinsing cycle. The agitation in both laundry and dry cleaning processes can not be replicated by hand washing. I have a giant bag of anectdotal ideas for this.
Ive been thinking on this one for awhile now. What about an AOR1 or AOR 2 pattern. How would those stack up as far as reflectivity and silhouette disbursement?
US Army issue woodland pattern is amazingly hard to pick out with night vision... until some officer starched the hell out of his uniform. Then they glow in the dark.
I've done a ton of tests with both starched and unstarched M81 uniforms. All issued. Every single piece and every single fabric glows under NIR light, with only the black elements staying dark.
I recall when BDU's first came out. You were not supposed to put starch, dry clean or press them because of their IR blocking ability. So, what did everyone start doing? They starched, dry cleaned and pressed them, so that they had that crisp sharp appearance...... Oh, and yes, they highly polished their black leather boots, too.
A fascinating subject and I applaud your efforts to bring attention to IR reflective materials. I'm aware that significant researh in the field was being conducted by the Germans in WW2 on patterns and materials. But, it's interesting to see how those same issues relate in today's world. Thank you!
A most excellent video. While I'd like to see different camo patterns under night vision, I think you are totally right. It depends on what detergent you use. I would absolutely love to see a video on that. Well done Sir 👍
Check out Sport Wash from Atsko and also look at the UV blocking dye. It is for UV not IR but will help cover the brighters that are in other detergents. Thanks for the hard work on this issue.
Looks like burlap would be a good way to reduce your signature. I've got some burlap grain bags I've been saving for use in making a ghillie suit for hunting purposes. Going to have to get with a buddy of mine and see how well he can cab see if.
Yes I would like to see how detergents affect the NV signature. I also would like to see how various wool sweaters and possibly merino wool fabrics show up. Surprising to see such poor performance on so many fabrics.
Just a suggestion. But if you want to avoid night vision or even IR then paint you cloths in Vantablack. It is nearly a perfect blackbody. If absorbs 99.996% of all electromagnetic energy. This is to include IR, UV and visible light. It ain't gonna be cheap but I figure if you are trying to avoid Night vision and FLIR then you did something to make the expenditure worth it.
Thank you for doing this. Very helpful. That use of children as fashion accessories, isn't new. By the way, use of plant dyes to color your hunting outfit. Walnut hulls were used at one time. Or maybe get all Jackson Pollock with some old burned coffee. The coffee is well known in the U.S. Navy.
Materials that don't reflect IR are: Nylon (shows as black) Rayon (shows as black) Cordura (dark gray) NyCO (Nylon/Cordura mix) (dark gray) and random dies used in some materials which you'll just have to look at under NV to determine. Cotton is bright as shit. Polyester is a neon sign. Black magic marker will turn anything into a non-reflective surface (90-95 percent). This goes for cloth and firearm surfaces, even if they're metal.
I wonder how wool looks to night vision. Those old fashioned Woolrich hunting pants, the green wool ones or taking a wool surplus blanket and making a poncho would work against night vision.
I think using a different type of detergent would be better, like maybe Dawn dishwashing detergent. Dishwashing detergent it's not supposed to leave anything behind on the dish that you will be drinking from.
Yes plz do a video with uv blocking dyes I know they make them it would be cool to see how or if u can make your clothing NIR compliant or pretty close
I feel like this is relevant. Went camping with my buddy last week. He drives a new white 2021 4runner, and I drive a white 2017 4 door Jeep Wrangler that I wrapped in Matte Green. It has some dirt on it and I haven’t washed it in a month or two. Without using my PVS-14 you could clearly spot the 4runner in a dark forest about 30 yards from a small camp fire. My Jeep was next to it, and completely invisible in those conditions. I then put my L3 WP 2376+ FOM PVS-14 on, and the Jeep was still very hard to identify. The only thing that really stood out were my white wheel wells that I haven’t rhino-lined yet. Just some food for thought. Matte vinyl wraps and some dirt can really help in keeping your vehicle concealed in a forest.
The old desert night parka worked great against Night Vision beyond 25 or 30 meters. We used them as OP4 and combined with slow movement we could get stupid close before detected even with night vision. It was always a mystery... let me cavoite this by saying it was 1990 NVG's the parka may not hold up against newer equipment.
Hopefully this will be seen. Two other things that might be worth testing with both thermal and IR imaging. One is simple "Lenticular sheet" which can make you visually disappear. And the othe, which some may consider rather lame, but interesting as Airsofters have used it to visually hide, but what about in IR and Thermals with the portable angled mirror panels? You do get that thermal break if it is tall enough, but what will it look like under thermal and IR?
Great job! Love these videos! Please do more. Detergents and ir compliant clothing would be my recommendations. I thought all licensed multicam was ir compliant but that piece wasn't too impressive. Would also be interested in more rifle accessories, slings, optics, etc. Going to watch your paint video now.
I was told that wool works good, have you ever tested that? If I remember correctly, I think I heard somewhere...... that sometimes Iraqi fighters or some shit have used them against American forces hiding in little holes or cracks in the mountains and would cover theirselves with wool blankets to hide from ir..... I have no idea if it's true just something I heard.
The structure doesn't matter on most synthetics. The material itself is just reflective to IR light. A simple test is to put your hand close to it. If it feels warm, it probably reflects Ir light. Polyacryl for example, does reflect down to the thermal Infrared part of the spectrum. Which is why it's performing better in cold weather clothing, as it reflects body heat, thus increasing the insulation. Also leather is not made equally. Even the shoe cream you use makes a difference. Military stuff will in most cases help with the IR camouflage on leather and even refresh it.
What about wool? Different kings of organic threads? What pigments do worse and better? What about after washing (with or without brighteners, etc)? What about after extended use or when dirty? What about wet vs dry? Wet vs dry when dirty?
using used clothing was best over new. no one is going to have new stuff after the first day of wear. However, the purpose of night vision is to make things see-able in the dark. Thus, it all should show up. The color of the object may become important if you are behind another object, such as a bush. Having similar colors as the bush will distort your outline. That is why thermal is popular. Rough leather, non-black, is least reflecting. Black, if you notice, stands out. Yes, it was less reflective of the other side, but it still was clearly visible. Night Vision is about making the night day, so if you can see it in the day, you can see it with night vision at night.
I want to now see how different detergents compare to these. IOW how bad do they make you glow, because I know they do make you glow. But is there a not as bad option.
IR deterioration usually takes multiple washes to make a noticeable impact on clothing that is IR compliant and treated (i.e. a camouflage utility uniform bought from an Exchange). If your clothing is already "bad" without being washed then using stuff like oxiclean or other detergents with optical boosters will only make them worse. But even then it will take more than a single wash to make a noticeable difference.
If you do anymore of these videos could you try to add old-school or even new school wool clothing like camo-wool pants and sweater? I live in rainy ass washington and wool happens to work really well for holding body heat even though you've become rather soaked and wet. Just a thought! Thank you, hooah hooah ranger push-ups ftw
I remember reading a forum some years ago, that said to watch out for the types of washing detergent you use on your clothes. Some detergent can brighten up your clothes more than others, apparently. They had a list pointing out the good ones from the bad, but I do not remember what chemicals was causing the clothes to brighten up. Maybe this would help point out some things to avoid? Or maybe even be worth researching later on?
HEY BROTHER, AS A US MARINE (former active) I only had the old woodland army/marine/mitary pattern which I always hated. When I got out of active duty I got a pair of AUTHENTIC USGI DIGITALS BLOUSE (top for all other services) AND PANTS WHY DONT YOU GET THOSE USGI USMC ISSUE PAIRINGS AND TRY EM OUT ON YOUR VIDEO PAGE? THEIR SUPPOSED TO HAVE THAT UV IR CAMMO MADE INTO THE PATTERN. I haven't even witn em as a pair yet and their still brand new NEVER WASHED AND THEIR STRIAGHT FROM THE US MIMITARY BASE.
My buddy uses a UV killer wash on his hunting camo, old nam era woodland, pattern gear. We tested this with short range and long range UV light Worked. What amazed me was how many right out of the factory clothes had large random areas of UV reactive color. Haha Includeing a lot of camo gear. Some of it new mil spec issue. ( not so funny). The only night vision I have ever used was older 2 gen tube Probubly Russian monocular unit. So never tested it for NV gear " camo". Got not worried about thermal imaging when I seen first civilian units. That was my oh shite moment. Now from your small study, in sure what we used to defeat the TI gear would stand out to NV gear. Dang..... No mercy.
So, after washing the clothes with detergent, they should be washed with only hot water once or twice afterwards? And maybe some other things like drying them in between the three washes, also I saw a video where someone sprayed something on a backpack that you pretty much can't see, but it did affect how it looked with a night vision camera.
