You’re missing point. When you pour boiling water into a single wall metal cup, the cup quickly obtains the same temperature and becomes uncomfortable to touch with hands or lips. Thus the handles. A double walled cup doesn’t conduct heat (as easily) and thus is pleasant to hold and drink from. Handles are not necessary on a double walled cup, so loose those for weight savings.

I was going to buy a Toaks Titanium Cup at REI the other night. I saw both the single and double wall models and the $20 price difference. Thank you for the testing and review. I favor the single wall after watching this. Nice clarification on the ability to boil as well. That was another question I had. -Kyle

Got to keep that Java hot while lounging in the hammock in the mornings. Great comparison Rob. Thanks again keep up the great work.

This is great mate, thanks a lot for sharing and proving your theories!

I have the 600 double wall cup, originally chose it over the single to keep from burning my lips. It also works good for warming cold hands. After using it several times I started setting my pot of food over it, that eliminates the need for a pot koozie. By the time I break or setup camp my food is completly done, and both the meal and beverage are still nice and hot.

I settled into my Toaks 750/450 nesting kit about 18 months ago and love it. I gave serious consideration to the double-walled 450 cup, but figured at the extra weight and doubled price, it wasn't worth it. The way I saw it, the beverage is still losing heat from the open top, so unless the double-walled mug had a sealed lid, it wouldn't make that big of a difference. Instead, I made a reflectix cozy for my 450 cup, and it stays in that cozy until I get home and take it out to wash it. The 450 in its cozy nests perfectly in the 750. It's a great setup.

Hey ... very helpful. Exactly what I was curious about when shopping. Thanks!

Just found your channel, love the content! Thanks for the reviews:)

Very well shot and detailed review, thanks Rob.

Thanks for the info Rob! Cheers!

Thanks you just saved me at least $20. I was just getting ready to buy that cup. Thanks for what you do.

Lots of useful information in this video! I have a no-name titanium single wall cup but I prefer to take my plastic GSI Outdoors Infinity mug with me more often than not! :-)

Glad you made that review Rob.

Good review Rob. For me the reason to carry a metal cup is in the event I have to cook directly in it. It's sort of a back-up as I use an integrated pot/stove system and if somehow the pot got destroyed I have the secondary metal cup.. I don't like drinking from the pot, so I pour it into a smaller cup that is easier to handle and more enjoyable to drink out of. I might give the single wall a try, will probably opt for the 375ml with the lid.

Great video thanks for helping me decide

I did go with the double wall mug the two ounces wasn't a huge deal to me, that price though....ouch! Here was my reasoning... though the extra heat retention wasn't a huge deal... the fact that I wouldn't scald my lips on a hot mug was. Not sure it was worth the extra cost and size, but there is a significant difference in the outside temp of the mug oh and also the double wall seems a good bit sturdier.

Worth it. 7 degrees makes a difference. 120 vs 127 for coffee, yes. BUT, of course 95% of the heat escapes from the top. Had the top been covered on both, the double wall would have crushed the single wall.

Since heat goes up, what will the heat loss look like if you use a cup cover? Will the sideways heat escape at the same rate?

I agree. The degrees to dollars ratio isn't quite there, lol. Great video Rob!

Double wall is far more rigid. But even more importantly, it also prevent condensation of cold beverages in the summer! And you can hold hot beverages easier, if you don't use the handles...

test should've been done with lids on both. double-wall cup's obvious advantage would be on heat dispersion ratio along its "walls"

thank you, this makes sense to me.

Unless it's actually insulated between those double walls, titanium is such a great conductor that it's no surprise the difference was so negligible.

Thanks for the review! Out of curiosity, what kind of 750ml cup do you use?

I've been meaning to buy a double wall mug, but the main reason is they don't burn your lips.. the bonus would of been heat retention. seems I win on one point but the second ain't commin into play like I imagined.

Single walled cup with a DIY pot cozy. Doesn’t get better than that tbh. Mines aluminum - cheaper and lighter than most titanium stuff of the same capacity. I use a pot gripper for that and my pot when I cook. One handle for everything = weight savings

Good timing Rob!I'm in the search for a titanium cup!!! Thank you for the valuable info 👍👍🤗

You can get the single walled mug with a lid. That should make a huge difference.

I’m not 100% sure but I’m pretty sure the double wall is so you can hold the container without burning your hands

I own both. The difference is found when you use the lids

After drinking a lot of cold coffees in cold weather i bought a 300ml double wall ti mug with lid at aliexpress. It's been a gamechanger, now i can enjoy hot coffee. I liked your test, but in a cold windy day, it seems that the double wall really works. Maybe is the lid, or the double wall... i don't know, but it works.

Titanium is VERY thermally conductive. My single wall burns the hell out of my hands and lips, that’s the main purpose of the double wall.

great job

One question did the double wall burn your hand like the regular cup?

The lid make difference. Vaporization takes most of heat. Like a thermos bottle radiation is very small portion of heat lost and cause of that bottle feel lukewarm to hand.

Ive learned while camping. You really dont need much. Like my coffee or tea is gonna get cold. lol☺

2:38 - to skip the intro.

Hi Rob…..hope you’re still there?….one question about this mug experiment?, how did the mugs feel in the hand with boiled water inside?, was the difference noticeable that the twin walled was cooler?….I guess so, but your comments would be appreciated. Thanks, Rob 🇬🇧

This is video i look for ...just bought snow peak single wall cup i was wonder what is a difference

I was wondering more about scalding my hand. Not a digital measurement, but more an emotional estimation.

it's because you didn't put a lid on, the open air is cooling the water. A lid on both, the double wall will be a bit warmer. I have the snow peak double wall and it keeps my coffee way warmer longer. snow peak sells a lid

Hello. I watched this test to decide to buy or not a double walled titanium mug or not. And I have a question/test for you to do. I have older aluminium single walled mugs, from the time I was a boy scout, and have now a more modern sea to summit plastic mug, and also a double walled stainless steel mug. I stopped using my older aluminium mug, because its that really cheap aluminium that preserves every odor that you put in, and by the time you don't burn your lips in the lid, my tea isn't warm anymore. The Plastic mug is much more pleasant to use, but I do a lot of cooking by the fire, (fire and plastic are not good friends) Now the double walled stainless is the best, the negative side is the weight. Now the test for you is to try and drink hot/warm coffee or tea out of both, single/double walled and confirm the safety of your lips. The thing is that in the single wall that wall is going to be at the same or so temperature of the liquid, whereas the double walled no, it mimics a porcelain mug. Thanks. Bruno Fernandes , Portugal.

On it's face this was a fair test, but it's actually not. A lid is the difference, and by that, I mean that with no lid the double wall is barely in use and it's basically a standard cup with that giant heat escaping hole. If you were to redo this with a lid on BOTH cups, the difference would be night and day. Imagine taking a double wall 24 cold tumbler and putting ice water in it without a lid...10 hours or less it's all water...but add the lid and you get a full day. I'll bet with a lid on them you would get a 40 degree difference or better after say an hour in that cold.

That was interesting and well done! I think the real advantage of a double wall mug is to insulate your lips😀. Hot coffee in a single wall Toaks mug is well....really really hot🔥! I use silicone Hotlips. Nice job👍 Wade

When I drink from a singele wall mug, it will burn my lips. The double wall cup feels better.

Can I have that double wall titanium cups you throw?

Nice job,saved me 20 bucks.

single for the win

Will the difference be more significant if you will use Ti or Silicone covers for both mugs. Some mugs are supplied with a cover. I've bought recently 650ml single wall Ti mug and what I didn't like is that it gets extremely hot. I thought even single wall mug could be more comfortable to hold. One should be very carefull where he puts this cup on, not to damage furniture. Yes, I've bought it mainly for home use. Another thing - handles are too tiny. I'd prefer them to be much thicker.

This was eye-opening. I thought there would be a _much_ bigger difference. I mean, you pay about double the price for a Double Wall vs. Single Wall mug. You can't use a DW mug for cooking; only drinking out of. And all you get is 7 degrees difference after 20 minutes? And realistically speaking, if you're out in the cold with a hot beverage, you'll be done with it in 10 minutes. Which in this case was only a 4 degree difference. Why buy something that you can't use directly on a fire or stove, that costs twice as much, and barely does a better job of keeping your hot beverage hot in comparison to something less expensive and more versatile? I have one DW mug. A cheap stainless steel one I bought from Wal-Mart under their in-store Ozark Trail brand. It even came with a sip-lid. No folding handles. But to be honest, glad I didn't spend the money on a titanium DW mug.

All i know is that double walls are easy on the lips. I have a stainless steel 470 ml cup for which I paid 6pounds sterling on amazon and I will never have a single wall ever again

Double wall is easier on the lips with hot liquid

So.... my girlfriend really really REALLY likes tea. And it needs to be hot! So, I've been looking at the double-wall mugs, and also the Snow Peak Silicone lid. I'd be quite interested to know if the lid makes a difference, and if so, how much?

Ended too early. You like to drink it in 20 minutes, some people for much longer.

Calling sick and weak for his own video, weak review. I can not find that Subscribe switch, 👀

Please do not shake things at the camera. 👎

Not worth extra $$$$. My coffee won't last 20 minutes. Thanks
