My Dad spent WWII in the South Pacific. He taught us this method as well as using a fly over a tent, shelter-half, or another tarpaulin just for the heat relef. He also carried a folded section of inner tube (about 18") so he always had a dry spot to sit. These methods worked camping, hiking, and campaigning.

my dad taught me this back in the 70's. and I have used it many times. something he added to it if you have access to a water, source, even if it is not potable, dampen the inside of the V on both panels and you will benefit from the evaporative cooling on the air flowing as well.

Very cool! I see how this works, hot air rises creating draw. I've set up dual tarps many a times experimenting with this and now I see some set ups I did were actually trapping hot air.

We use a similar idea when we take our camper trailer out for a weekend during the summer. I have a silver coloured tarp and 8 extension poles that is 6m X 9m that completely covers the camper trailer and annex to reflect the bulk of the sunlight heat before getting to the canvas sleeping and annex section. Regards, Jas.

Wow ! " EXCELLENT Idea - Perfect ! My Navy SERE - POW Instructor team designed the first " Desert Survival " program for pilots students , etc. at Warner Springs, Ca. Det. back in 1970's. NAF El Centro , Ca was the testing area. ( Ugh ! 100 - 110+ temps. ). We used the military manual " Desert Shade Shelter " idea with dug a ground trough bed ( like my Aussie pup uses, ha.) 2 layers of parachute , creating the inner air space and a space blanket on the top = reflecting the sun and creating a rescue signal. YOUR IDEA IS EXCELLENT ! , Thank You . I sure will test it here in W. Colorado, tipi camp. " Mtn Mel " , Ret. USN SERE - JEST - DEST Inst. 59- 82. VN Vet.

Very glad to see and hear others are using this technique too. Learned this as a stump jumper running aerial fiber in Texas. Literally saved my life a couple times.

Once again, I learn something I have never seen before! This is one of the very few channels that ever happens with. Great technique!

Impressive! I have never thought about this.

Thank you for the info. I watched it 5 times . You explain it in very easy to understand terms. I am not embarrassed to admit that I watched it 5 times. When I studied electronics at school I did the same thing by reading and studying the material over and over and that way I had a good understanding

You know this is the first time I've ever seen this, and it's ingenious, I might try this and take some temperature measurements, I like it.

I did something similar when working my way through college at a boatyard. The first time I did it, my boss was watching me like a hawk and was about to dock my pay for screwing around, but noticed I was able to work longer periods at a time than my cohorts. Memphis summer sun is no joke.

Wow! Great idea and the other comments show it's a well recognized system. Thank you for sharing this with those of us who didn't know about it.

I’d love to see a side by side comparison on a sunny day where you measure the ground temperature after an hour or so. Great video thanks for sharing.

Excellent advice as always. As someone who has spent a lot of time in the outback in summer I can confirm all those things you talk about make a huge difference.

Finally someone who understands physics of heat transfer!

Once again proving the wisdom of my Elders ... I can always learn something useful from others if I'll listen more than I talk. Thank you for this brilliant tip! (As you said, you learned it from another fellow.) Glad you took the time to pass it along to the rest of us! God Bless

Been in the woods since your last Tuesday tip. I used this exact trick. No rain here this past week so the only reason I brought a tarp was to double up on my hammock for the coolness. Works great. Good job as always Blackie. 👍

That is so bloody simple, thanks. Ive been miserable inside a one layer tent. Never thought of using a tarp, freaking brilliant!

I can testify that this works. I have used it in the AZ deserts and in Italy. I have mostly used it with tracking poles because trees were few and far in between. Travel was done in the cool of mornings and evenings. It the noon heat it was time for a siesta.

Wow. I never knew there was so much science in a simple tarp. That was interesting.

They’ve used a similar principle on Land Rover defenders for decades in vehicles prepared for very hot climates. They have a secondary roof skin a couple of inches above the normal one with an open gap to let the heat disperse when moving.

Good science lesson. Thanks for sharing. I will remember this. with summer coming.

Thank you so much for sharing your experience and knowledge with us!

Great information, Brother !!! We were taught that in several survival manuals in the military. Keep up the great work !!!

Great tip Blackie, very scientific. Thanks, I'll have to remember that for sure.👍

You answered a question from our '60s Scouting trips! We backpacked/camped with tarps here in Western Oregon where rain is the main concern and a standard A-frame works best. But we looked for cooler designs when camping in the chaparral or desert of Eastern Oregon, a plow pitch had some effect--if only we'd just turned the A-frame upside down! Thanks

OUTSTANDING!

Very good Mr. Thomas. Thanks for the knowledge, I'll never forget it. Peace.....

So well explained, thank you for teaching

Good general outdoor comfort and survival info! The kind of video KZfaq should get behind more of! Thumbs up

I call it insulated shade. I do this trick with my easy up when I do farmers markets, I put an extra wall On the Sunny Side it makes a huge difference.

Thinking about it this set up makes sense. Thumb up for bringing it to light.

Land Rover used this system on their all terrain vehicles years ago. It was called a safari roof. The roof of the vehicle had a second roof panel giving a gap of about three inches above the actual sealed roof, the top one being open all around to allow air flow through when driving which would cool the inner cab. I don't know why it's still no longer used because it was actually very effective in use.

Great explanation and great idea

Physics meets bushcraft bloody awesome

excellent advice. i'm a tarp user all the time and this advise is great....thanks

This is brilliant!

Very good informative video! Thanks for sharing...

This is a fantastic tip! Thanks so much!

God dang it Blackie you always come up with the best ideas and tricks that always works. Thank you I will be using this idea.

Good explanation, makes sense. Thank you, thumbs up

Thanks Blackie. Great tip.

Brilliant! Going to love using this here in arizona!!

What a great idea thank you for the tip. Makes perfect sense.

Never seen this before, it’s like a reverse super shelter. Thanks Blackie, great info.

I'm impressed with this! Got the science of it figured out and all, cool tip Blackie.

Excellent video, with a clear explanation of the physics of convection, and thermo-dynamics; dead air spaces triumph again :-) :-) Cheers.

I am known as a "Tarp Master" by my camping friends. This is a GREAT technique! I will incorporate it into my bag of tricks! Thanks!

Great tip. Thanks

That's good to know. COOL trick.

Short course in Thermo Dynamics 😁. Interesting how much Bush craft is geometric, physics, and other of the "Advanced science's". But a much better classroom.

Great tip, Blackie! Thanks for sharing.

Awesome tip! Thanks for making this video :)

Thanks Blacky ! As always I have learned something great from you!

I had no idea! This is brilliant. Thank you for teaching me

This is fantastic. How not to bake on a sunny day here in SC. Thank you. God bless.

Got to love the power of dead air space great video!

Well I will just be damned!!! And here I thought I already knew everything!🤣🤔 I have had to stretch a tarp, poncho, lay pine boughs, etc hoping for a little shade, but never knew about this trick. Simple, but oh so effective. I will learn how to set this up, and definitely use it. Thank's for teaching this old dog a new trick. By this video alone, you just grabbed a new subscriber. Be safe. Be well. Roger

excellent..and on my Birthday too ! thank you Sir

Very interesting!!! I'm a science teacher and this makes perfect sense. I may test this and report back with actual data. Thank you for sharing.

Thanks Blackie! I live in the Chihuahuan Desert of west Texas so this is good stuff to know! 👍

Awesome Idea!

Tarp trick, amazing friend

Hello my Outdoors friend, thank you for sharing this very informative video. All the best to you, stay healthy. 🤗

Damn!! This man just dropped some serious tarp science ... BOOM! 👍

Thanks for the video.

Living in AZ this is a very useful tarp design! TY 😎👍

Top shelf content, thanks, Blackie

Smart. Thanks for the physics lesson. I like reality.

ANYTHING to beat some of this heat in the ozark foothills is going to be a God send!!thank you.

Summer in full swing here, Thank you Blackie for taking the time to share this tip, I will give this a try.

Love the knowledge you drop on all your videos!

I really appreciate the physics behind this. I learned something. 👍

Great video and great information. I will remember this.

This is great! Most of the videos I've seen deal with retaining heat as opposed to keeping cool. Perhaps that's due to me being on North American continent so I think that way... I see video of guys building cave shelters and I wonder why they don't build the fireplace with fire box inside shelter with a big flat stone to heat up to possibly cook on and retain heat inside shelter even after fire is out. Fire beds in cold isolated areas are well known in the North. If you have a reflective tarp or space blanket that would be a big plus to help keeping cool in the heat and warm in the cold...

Great video makes sense thanks for sharing.

Thanks. Good tip.

Some good advice. Thanks

I do basically the same thing with my super fly trap and a space blanket . I put my super fly in porch mode , then I hang the space blanket with shinny side out at same angle and gap as yours. Really makes a difference when resting in my hammock. If it rains the water just goes down and out the bottom between the two. Ipu

Mannnn i absolutely love your channel !!!!!!!!

Great tip, BT. Thank you.

This is very cool!

That's a doggone good idea. Thanks for the tip!

Neat idea. Thanks for an informative video.

awesome video... and it does work very well have used it many times

Woe, 😯🤔🤔.. Agreed with aggyMI!! And in humid Indiana, I need to try this!.. Thanks brother... Hoobilly.

love your channel and tips just got a pietta 1858 new model army . the cilnder spring broke before I even shot it thanks for the 1858 disability video God bless you and your family.

Great video! Will try this!

Great Tip!

Great video!. Great shirt. Knowledge equals BE PREPARED! :)

An excellent video.

Thanks for your knowledge

Slicker than owl snot on a winder right there!

Awesome trick Blackie. 👍

Very clever , thanks .

Great tip never heard about this thanks for the upload!

This is valuable information people… at least give his video a LIKE. Thank you Blackie. I always wondered why I was still so hot behind my tarp but cooler behind a tree or solid object.

Great tip. TY.

Something new to experiment with, thanks for sharing buddy. I am from UK so there's only a handful of days a year that would necessitate this kind of shelter, plus our native woodland is nearly all broadleaf but appreciate you taking the time to show us. Cheers and all the best from England.

Good Tip, Thanks.
