Greetings, KZreadrs!
It's the internet, right? You see a lot of gear-related claims being made, but often without any supporting evidence to back them up. My goal is to examine these gear legends one by one to separate the facts from the folklore, provide objective analysis with factual references, and hopefully have some fun along the way!

That's how you make an excellent and complete informative video. Loved the scientific approach
Thanks! That is much appreciated.
Canadian Army used inflated pads, the carry case doubled as an inflation bag. Found in extreme cold some who blew it up by mouth could not deflate in the morning because the valve froze. Figured some saliva would get in there also as they blew.
doing the Lord's work lol, well done. pretty sure KZread sent me here after watching a video where a guy used a Soto Amicus and went through 2 canisters and into a 3rd while his partner was still on their first canister using a Jetboil Minimo. These setups really seem to shine over long-haul scenarios where the efficiency really pays off. Anyway, thanks for sharing!
Very interesting! I am a boot hiker, always have been, but was wondering about switching to trainers for lightness. Good to know that, at my speeds, with the flexibility of my boots, I wouldn't be gaining anything. I love my high and mid boots. They've carried me far.
I enjoyed this video as I’ve been looking into heat exchanger pots and stove combos in the future I’d love to see a comparison on heat exchanger setups vs wind shielded setups and fuel use. You may also want to check out the Bulin stove and pot combo the fins on the bottom of the pot are longer and covered with an additional cup piece on the bottom of the pot I’d be interested to see the correlation of the exchanger pots and their types of fins and the length of the fins.
Yes! It is coming. I just need to wait until it cools down in my shop.
So well done. Thank you
You’re welcome! Hope it helps.
This guy. THIS GUY. He answered questions I didn't even know I had.
Wicked surprising. Not the results, but the entertainment value. How is it possible that a cannot suffer regular speed through an 8-12 minute gear review video with all sorts of effort put into cinematography, but I could not bear to fast forward even one minute of this video!
First off, thank you. These videos have me looking at my food in a completely different way. I have a question, how much water do you add to your recovery drink?
You’re welcome! I use about 16oz. It is flexible, though. It gets pretty strongly sweet if you use less water, and don’t do more than a liter (see the video on hydration strategies for the limits of what your body can process at one time).
What about using the skin turgor test (ie pinching the back of your knuckles and watching how quickly it bounces back) as an additional guide to hydration levels in the context of hiking? Is that something useful to monitor? It seems to have the convenience of being done on demand, rather than only when the urge to pee comes and having to judge the colour under uncertain lighting and background colour conditions.
Thank you so much Ive been looking all over for someone with the knowledge to be able to dissect this wonderful idea
I love your videos, but I think they would be more, um, palatable and understandable if you cut them down to a third of the length, and then had a separate video with all the details in case someone wanted to do a deep dive. Also, I would adjust the overhead camera so the viewer doesn’t feel like they are hanging upside down. But amazing content nevertheless.
Dude I am blown away by this video. I fully intended to just grab the highlights but here I am an hour later. I can't believe I am only just now finding your channel. Keep up the great work
Thanks! Welcome down the rabbit hole 😉
Interesting, nice to see scientific method applied to testing gear. How about testing painting the base of your pan black, would that increase fuel efficiency? Would be interesting to know.
Good idea. I plan to do some materials testing (comparing pots of aluminum, titanium, steel). Probably put black pots in that run.
Slight quibble: R-value is not "resistance to conductive heat." The measurement is heat transfer mechanism agnostic.

Loved it. I am a Mech Eng and spent 4 years doing heat transfer and fluid flow. As I said loved it.
Awesome! Thanks!
Adding something that's rarely discussed, extreme temp changes. Example, was in a very hot environment for months up to 125° , then was sent to Germany for a bit for training, then back to the gates of hell. That short time in a much cooler environment "snow on the ground" kicked my butt. Was consuming 3 GALLONS of fluids, 2 liter of water to 1 liter of electrolytes. Here's what I found and experienced, when exposed to such a extreme temperature change your skin begins to filter your blood similar to your kidneys. Your sweat will smell like PISS. Only had to pee 4 times the entire day but that was in the afternoon. Something else I observed was my bodies desire to clear the bowels out to help with absorption. That 3 days without water is for someone in an air conditioned environment and not performing any activities.

It’s on there! (The list has been updated since the video)
I have a question for you! Given that we need water, what is the big deal about consumables with lots of water weight? Does getting it by eating just reduce the number of times we hit our water bottles? Food for thought (pun intended). Thanks for the awesome vids, and Happy Glycogen-preserving!
Well, you can set out with 7 days of food without too much problem. Try carrying 7 days of water! 😱
Something I'm curious about is a different design on the heat exchangers. A coiled exchanger design should retain most of its efficiency and reduce the effect of wind. You also discussed how often people resupply, resupplying often is not efficient and adds steps. I'm one of those oddballs that has no issue going a month without going to town.
How many hours did you spend getting us these awesome nerding out facts?
Dozens and dozens 🤓
This has been on my mind lately, happy i found this
Probably my favourite outdoor channel period. Thanks for doing what you do. I will continue to refer people to your content!
Oh, and I carry a pump because I don't enjoy being dizzy from blowing up my massive Exped pads.
Very kind of you! And I can’t disagree about the convenience of a pump 😉
I cannot express the level of gratitude and appreciation I have for your content! The scientific comparisons and breakdowns are invaluable. You're amazing!
Thanks very much! It is appreciated and I am glad if it can help.
I used to lay asphalt for a living, 10-14 hrs per day 5 days per week. Our machine and work area routinely exceeded 140°F and in the hottest parts of summer was touching 160°F. It must be possible for the human body to learn to operate at much higher than 2% dehydration. Not a single one of us ever consumed more than 2.5 gallons of liquid per day and nobody died. Human bodies are indeed a marvel of workmanship, maybe not the best engineered lol. This makes me want to touch on the symptoms of dehydration. Nobody ever talks about the very 1st symptom being a runny nose. If you are out in the heat and you notice your nose has started running, you better start hydrating. If it has reached the next stage of less sweat, find shade and hydrate. After this comes the shakes, this is dangerous territory and will likely need ice/cold running water and hydration supplements. Next is loss of muscle strength/motor control. At this point, and any point past this, medical assistance may be required Vomiting at any of these stages requires immediate medical assistance.
Brilliant channel.
This man is a national treasure. Protect him at all costs
You could test the flame gap theory with the Petrel. Run it with the pot supports in the slots and then with it not in the slots. Everything remains the same, except the gap.
Yes! I plan to try that when I do the wind testing.
Favorite glucose recovery treat. Mt. Dew is the nectar of the gods.
Hypothesis, one could probably take the Petrel pot and not use those slots for the stove arms, increasing the gap and allowing the flame to develop in the center of the pot, and possibly increasing efficiency. (Possible downside instability.)
Yes! I plan to test it both ways when I do the wind testing.
The nerd in me rejoices!
🤓
Getting ready for a 5 day 4 night trip to a place that requires bear cannister. Thank you for this. I think I am going to repack my dehydrated meal packs into ziplocks because wow they do take up a lot of space without repacking them.
Awesome! Like always is!
Thank you for the time and patience in compiling information and making it easily digestible
TL;DR The quoted paper is not science, hence the recommendations are suspect, read Waterlogged book by Noakes. You quote 2009 article by "a Canadian elite-level runner and triathlete. He received a Ph.D. in organic chemistry ", which presents "a mathematical and scientific model". One major flaw, that renders all his calculations irrelevant is "The sodium content of sweat is set at 40 mM (range 20-80 mM) meaning that 1 L of sweat would contain 920 mg of sodium". The fact is sodium loss rate slows down as serum Na goes down! The author should have read Waterlogged more closely and so should the author of this video. Why would you base your recommendations on some obscure not peer reviewed web article? Yes, it's hard to find good science on hydration, but start with the Waterlogged book. Cheers.
Petrel has the benefit of adjusting the burner gap. Be interested to know results of petrel if burner isn't used inside the slots.
Agreed! When I do the wind testing, I will check it both ways.
Wow man - this is truly some hard work. I hope you reach an excellent amount of views some day for this effort. I will tell all my friends and family about this. Thanks for your research and brilliance!
Great review. I just received the Petrel and I did quick tests with brs300 and pocket rocket 2, and I had 4gr for 500gr water. Also they ship a set where they have Hornet stove which has pretty high distance to the pot. So I think stove choice is making a difference for Petrel.
Gear skeptic, you are the greatest. Thank you. I would love to see a video breaking down the best method of air mattress repair. I saw a method using hot glue that looked pretty promising. Thanks again!
Wow this was quality work, I learned a lot. Thank you! I very much enjoy how deep in the weeds this is.
Thank you!
You are very welcome!
Love your video, thank you!
Thank you for your work
I have to thank Brady Patterson at Outdoor Adventure School for directing me to your video. Very well done explanation/investigation - finally with a scientific foundation! I found it very informative and useful. Oh, and nice hands by the way...
🖐🏼🤚🏼 🤓
Came for a review, got a scientific paper. love it haha
I love that kind of craziness 😂 Thank you for this thorough testing and analysis.
Most welcome!
Thank you for the detail. Really helps me understand this stuff better.
You're welcome! I am glad to help.
