Easy to make, waterproof dry bags. No stitching; just cable ties, duct tape and super tough Tyvek. 

Great tutorial! They do make a tyvek tape which has an adhesive specially made for tyvek, and the tape itself is made of tyvek. I think this will hold up better in the long run than standard gaffer tape.

you may be able to fold it inside-out and then tape the interior seams, would add a lot of strength.

love how u made the square bottom part! genius!

Excellent video! I love how simple this was to make.

Thanks for showing this fantastic and money-saving build.

Really enjoying your videos. Love your straightforward delivery and clear instructions.

You are an excellent teacher/demonstrator. I love this video and look forward to all the other ones you have promised us. ;-)

Neat‼️ There was LOTS of this fabric behind the vinyl siding on my neighbor’s house‼️🤪 They won’t even miss it until the wind blows 🌬️ the loose siding away❗️😁

Excellent Project. Clear and understandable video instructions. I'll watch the video again and give it a try.

Absolutely loved this video. DIY, repurposing, repairing, restoring is my true calling. Subbed to your channel and I look for ward seeing what else you’ve come up with. Thanks! 🌿

Brilliant idea and excellent demonstration. I also thoroughly enjoyed your dry sense of humor.

Came for the project, stayed for the humor. Thanks for the laughs! You earned a new subscriber.

Love it Neil , really cool!!

I've been wanting to make a dry bag, thanks

Great idea and great instructional video!

Very good dry bag. It was a lot better than I expected. Thanks

What a clever man you are. I love this, I love the ethos and I also love making stuff. It is so satisfying making something beautiful/useful that could have cost you a lot more. Simon bloke in the woods inspired me and I had a go at making a wool smock, well it blows people’s minds when wearing it and I tell them I made it! 😊 💪 Instant sub! 👏

Ding dang I love this type of content!!🎉

I really love the energy and enthusiasm for practicality you bring to your videos. 😊 Sad there aren't more. This project is so useful for such simple materials. There are several homes being constructed in the area - I need to go ask if they have any scraps I could use. The bottom folds are brilliant: they don't require cutting or sewing, and I love that they add both structure and water resistance. Well done! Looking forward to more videos.

Excellent production values: Lighting, sound, scripting, pacing, camera work, and content. Well Done, Sir.

It's a nice idea but depends on the weatherproof qualities of tyvec and the glue life of gaffer tape. I've removed plenty of old tape that's been outside for a year or so where the glue has turned to powder. I actually made some 'moon' chair covers out of tyvec and they lasted fine for about 4-5 months but now leak slightly. I think tyvec recommends that a roof is covered with its final membrane, ie slates etc, no later than 3 months after applying the tyvec. I.e. don't leave tyvec exposed to weathering longer than that. I think these would be fine for a short term dry bag and of course you can make any size , nice idea.

you're excellent at presenting

the underrated intelligence of DIY better for cheaper

BRILLIANT!! Thanks for this! You've got yourself a new subscriber! 🤘😁

That looked awesome dad ❤😊😂

Dude, you are like the DIY parallel of the legendary Art Attack guy. Cheers!

Brilliant! Thank you😊

First video of yours I've seen. Nice workshop, looks good as a background but still seems functional. Ive got some left over banner material and might give this a shot. Thanks!

Just the right amount of knowledge, sarcasm, and dad jokes.

Very clever. Well done amigo.

Very nice presentation. Thanks.

Nice one Neil. I've subbed. Learned something new today. Cool bag

excellent. highly recommended.

Great video, I see you are just getting started at this RU-vid stuff. Well done, you have much success ahead of you!

Brilliant! Thanks!

Love the wit during narration……..

thank you for this video. i was considering getting a US surplus dry bag for like $35, but this seems like a fun project that i should try out my self. even If it doesn't work out, great i got to practice some DIY stuff and learn more about waterproofing.

Thank you for this! I am endeavoring to create a rain poncho that converts into a dry bag 😮. My plan is to use zipper, velcro and heavy duty snaps to make the bottom convertible. And probably put backpack straps on. I’ll post a link if it turns out worth while. Wish me luck!

Earned my sub. Great content.

Brilliant!

Very cool

Thks

BRIILL ! Very well done! & funny too :)

Just found your channel now subscribed very good

I found your channel scouring for drybag fabrication tips, getting serious Blue Peter/Johnny Ball flashbacks haha! I'll rewatch and pay attention once the warm fuzzies subside. 👍

I just got a hold of vinyl billboard material. Vinyl billboard is a sheet of vinyl that ads are printed on and attached to a billboard. Once those ads have expired, they take them down and they are thick vinyl sheets but the only thing is that they have prints on one side but the other side is usually white. I thank you for showing me this now I have ideas to make and duplicate drybags with D-rings that are like $50+ in Amazon.

Really good vid and earned my subscription. thanks. Id never heard a bradawl pronounced “broddle” like that (even my spellcheck underlined it) so I looked it up and found it's a Yorkshire dialect. I'm gonna keep that in my quiver for future use catching out those know-alls that like to correct people, looks in mirror and blushes. 😂

Thank you! Im gonna make one for my job (during working hours so I even get paid for it). For extra clothes and safety lines n stuff. Im currently using plastic bags for that but they break all the time. Hopefully this is a better solution.

I’m just came here for the accent. Beautiful :) thx

Great😊😊

Thanks¡¡¡👍🏻

Great idea, I've used Tyvek in the UK but moved to Thailand five years ago. I've learnt in that time that in general terms, Thai buildings do not use waterproofing membranes! So as much as I'd like to be able to make some of these for outside storage for wood etc (the number of insects here that eat wood!) I don't know how easy tyvek would be to buy. 🙄

Tyvek is generally very very different from all its lower cost alternatives. Take USPS shipping envelopes. They look like Tyvek but the holes you can't see are too big so they do let water through. Tyvek is indeed like Goretex, only lets through water vapor. Keep in mind that Goretex works exactly the same in both directions. Which ever side is warmer drives water vapor towards the other side. (You could take a Tyvex bag into the shower room and the heat could 'push' the vapor through into the cooler interior of the bag.) And 'The job's done," is not done. Neil needed to put a hose on it. Proof of concept. This is a nice project, but I'd consider these bags to be temporary. Maybe the kids are going off to camp. Maybe your going somewhere damp and foggy. I've made dry bags using Silnylon, plumbing 100% silicone caulking, some webbing, a clip, etc.. Costs a bit more, only a little bit more time, you do need a sewing machine -- but dead easy. The first one is the hardest. When done they're good for life. Here I think the belt/straps part is where it becomes complicated. (You could do those straps with a Speedy Stitcher one operation. Push the needle through, loose thread through the loop.... Google it.) Almost any sewing machine can sew webbing. The idea of a sewing machine is not that it pushes the needle through the fabric, but that it pushes the needle around the threads. You use a 'ball needle.' You can't see the ball, but it's there. I've got a Janome, best with a steel frame (it could be inside all that cute plastic). I've sewn webbing loops that'll take thousands of pounds/kilos. And something else about Goretex. It's great but. I do a lot of sailing. When it might rain, I wear my expensive Goretex jacket. If it is raining I wear my cheap yellow rubber jacket or the plastic jacket and rain pants I got in Japan. And the best demonstration of the Goretex Effect I think are Sealskinz socks. This is because the semipermeable fabric is right up against your skin. So your body heat is driving the water vapor. They aren't that warm, and when you put them on, you can feel moving air on your toes. But they don't let in water. My feet don't feel that cozy wool warm, but they also never get cold. End of a day of hiking in the rain in Dorset, wearing two pairs of smart wool -- my feet are cold (I have terrible circulation) Takes an hour to warm up in my sleeping bag. Next day Seakskinz? Same conditions. Feet warm enough all day, dry. End of the day feet dry, warm enough. In the sleeping bag? They warm up in a few minutes.

Loved the international Cup of coffee cost method.

Good instructable, I'll try making one myself. Have you tested the bags in real life? How durable are they? Wouldn't the tape start peeling off when in everyday use?

very coool thanks

I wonder how well rubber cement would hold up with this. Cool idea for a quick bag, subed thanks.

Did you taped it also from the Inside? Imagine, that this would also ensure to be save. Great Video man! Simple step by step description.

First class big bear

Nice idea, not sure they'd survive kayaking white water, but useful nonetheless. Would make great bergen or pannier liners though. Smaller versions would suit bags for electronics from getting wet. Getting really good gaffa tape these days is hard. Most of it is very substandard unless you're paying tenner a roll. I will investigate that material thiugh, good potential for tarps which have got stupid expensive now. If you get other colours even better. Useful video.

Tyvek has tons of uses. Nice video. Have you considered putting the tyvek through several wash cycles to make it softer before making the dry bags? I would be curious how the bags how up when you compress them to fit inside a kayak or your backpack.

Very inventive. The builders always put the tyvek label on the outside and that is the moisture shedding side. Have you dunked the bag? do the contents stay dry with the label on the inside?

Is the example you made the 55L bag? Great video by the way. Just made a custom one for my self-inflating sleeping pad for when I go kayaking. I made mine out of a 55 gallon contractor heavy duty trash bag 3mil thick. Turned out really nice.

Haha all I could think when you said the police in your back yard was There coming to take me away ha ha. Lol.

how are the zip ties holding up? have found that after about a year the zip ties break. i think the rivets would be a more durable solution. you have giving me ideas. thanks from minnesota, usa.

Specialist...

This same method using a very permeable fabric would be a guide on how to make grow bags.

The only issue is that they won’t last as long. But then as stated, not for super critical items

Super drybag

Thanks for the tutorial video friend. One question, why not use contact cement to reinforce the joints and overlaps? Subscribed, upvoted, commented (obviously) and I even rang the bell, so may the algorithm gods smile upon your channel.

Great idea and very well presented 👍🏻, Question… since the Tyvek sheet is waterproof one way but semi permeable the other way i.e. to let moisture out when used on roofing, just wondering should the side with “writing “ on it I.e. the branding be on outside as a bag so waterproof side out , that’s the way it’s usually laid on roofing [waterproof side up,so to speak ] when used as it’s primary purpose as a waterproofing membrane , …hope that makes sense 🤔

A dome tent made of tyvek would be an interesting project...

Do you think it would be possible to use this for making the skin on a folding kayak?

Tyvek can be ultrasonic friction welded as well as impulse sealed or stitched or all of the above...

Tyvek brand is more than other brands. Best use the ones for roofing, tougher than the wall cladding types. Don’t save on the gaffer tape, cheap ones come unstuck after a while

See you have a turbo lighter…they are so good and useful

How about a travel lock buckle system?

Why do you use the plastic strip for the roll loop? Surely it would still work if you just use a length of the black polyester strapping with the catches looped on either end.

Have you seen the NightHawkInLight waterproof tarp videos? Do you think that kind of treated cloth be viable for this purpose?

Something to keep in mind is that some tyvec is chemically treated to be mold and mildew resistant and you might not want that in contact with the things you're storing in the bag.

Would love to see you test the bags, I'm not convinced the gaffer tape makes them waterproof. Commercial ones are welded, not glued.

nice origami work. What is the benefit of the plastic strip/webbing clip arrangment? Wouldn't just the webbing be simpler?

Hello Neil SImmonds, I would really like to have the same product ingredients. In my country currently none or very few have this material (tyvek). Can we exchange information about these materials or also discuss other outdoor products?

Prestine shope ... And then a first price drill !

So I'm not familiar with the product you're using here but I am familiar with tyvek and with tyvec you would want the lettering on the outside as it acts like a one-way valve, so if you put it with the lettering inside it would be water resistant but with some slight pressure water would be able to move into the bag. Whereas if you put it with the lettering on the outside, it should be waterproof with the ability for moisture to come out. The product you're using looks more in line with a waterproof product though, so you might be safe on yours.

How to make the best hydrophobic

The webbing could be continuos frlm end to end and the tyvek rolled on it and glued

Is Gaffers tape Duct tape? Great Quick Bag!

Tyvek is not available where I live. I could get a small tarp and use the tarp fabric. The website says the material is polyethylane.

Where did you use the plastic sheet?

Is gaffer tape different from duct tape?

rubber mallet the tape its pressure sensitive tube of "shoe gue" might be nice.

could you list you supplier please, I can't find it anywhere near the price you mention in the UK. Many thanks

brilliant

Your mom told you to carry scissors in the "ice pick" knife stab mode? damn man I wont mess with your mom!🤣

How many Starbucks ups of coffee did not cost for the scissors? Gaffer Tape? Ruler? The international method of determining cost. Nice!

What is gaffer tape? Im in the us and all i can think is that it might be like duct tape.

can duct tape hold any weight at all?

What about sticking it together with impact glue 😁

It looks like Tyvek could be replaced by cheaper tarp for even more cost reduction
