Dropping July 15

 

Forsite - Lil’heroes

Adorable!

The colors really pop but the price pops my budget so those will be not something I'll try.

I like the bright colors and the character designs. I wish there was a picture of the diaper unfolded so we could see what it looks like on (or maybe there is a picture and I missed it?).

Ya also can't see a full pic of the diaper. Design looks a little busy maybe? Like there might not be much empty space. Forsite has always been expensive for the level of absorbency so good to see them step that up and not increase prices much.

A little confusing... "Out of Stock" but also "Available for pre-odrer, shipping July 15th".
 

It says absorbancy is 11,000 ml.  Now, if this were European, that comma is a decimal point and 11 ml is ridiculous little little. On the other hand, if that's 11000 ml, that's f**n 11 LITERS!!!  More than 3 GALLONS?!?!?!?!  Either way, color me 'skeptical'.

I can't comment on these specific diapers, but in general, my experience with ISO ratings is that they are as useful as maximum range estimates are, for electric cars. You can use them to compare models, but do not use them to plan your trip through Death Valley. 

I've done some field testing with other ultra-high-capacity-claim diapers in the same range - the Rearz/InControl BeDry Night and their Mega Inspire+ are both part of my standard operating procedures. This what I would say about both of those: they perform better than any other disposable diapers I have worn; I would also put NorthShore's MegaMax into this category, although they are a lot more expensive, at least in Canada. The make less fantastical capacity claims than the BeDry or Inspire+, but perform similarly, which is to say, any of them could last longer on me than I can generally manage to spend in one diaper. I usually have to get changed at some point to go out and run errands, during which, I don't want to look like I have a dead raccoon stuffed into my pants, and I don't like having to worry about if I might be taking on an "Eau de Nursing Home" bouquet. But, on those rare occasions where I've had 18-24 consecutive hours to marinade, while attempting to extract maximum value from one diaper, they have all help up their end of the deal better than most. I have not tried Trest, but I have no reason to assume they would be any worse or better. 

So, high compliments aside, let's machinegun the marketing puffery: 11 litres is, as pointed out above, 11 kilograms of fluid. That's 2.9 gallons, or more than 24 pounds, of fluid, in your pants. I do not consider a diaper to be synonymous with a bucket - IE, a device built purely for fluid containment. A diaper is a garment for fluid containment - something you wear. If you have to wear it while sitting in a bucket, then it has failed in its duty. So, once you can no longer wear a diaper, and also have it contain (IE, not leak) fluids, then, it has reached the end of its useful life. For the most part, I find that the wheels come off at about the 2.5-4 litre mark, depending on if you've been in one position, or moving around, as you used your convenient onboard toilet. 4 litres would be a stretch... at 3.5, you should only be sitting on things that you, yourself own. But, fortunately, most people emit between 1,800 and 2500 ml's of fluid in 24 hours, so... mission accomplished, unless you're doing a pub crawl. These diapers will most likely outlast your tolerance for being continually wet, and your lifestyle's tolerance for wearing enormous, sagging underpants.

As the owner of an EV I’d draw a distinction here.  The generally accepted Worldwide Harmonized Light Vehicles Test Procedure (WLTP) test is wildly optimistic but is at least based on a driven vehicle use-case. 

For me I find it overstates real-world range by between 20 – 25%

The nappy ISO test method (ISO 11948-1 if anybody is interested) is NOT based on the use case of wearing one and peeing in it.  It’s therefore probably unsurprising that its outcomes bear no relationship at all to real world performance.

I realise that it’s perfectly possible to build ISO-compliant concrete life jackets as its focused on standardised methods rather than performance outcomes but holy puddles Batman, this one truly misses the mark.

If we tested vehicle using off-beam methods such as ISO 11948-1 we should just push the cars out of aircraft at cruise altitude.  We can measure their 0 – 60mph acceleration time by how quickly they fall (fairly close numbers between models thanks to Galileo’s principle of free fall) and their top speed by their terminal velocity.

I would suggest that this product/ISO will be over-stating its REAL capacity by between 300 and 500%

Basically this is what I find although I'd range them down even further.  Even the best super-nappy in my experience becomes increasingly fragile for every drip over 2000ml (assuming you are not laying flat in bed which MIGHT see you get to 3000ml).

I've worn them for 24 hours.  It's not something I'd habitually do.  It's happened once or twice when I've kind of accidentally gone long-haul in one and decided that rather than change into a nappy that I'd be dumping again in 3 hours, I'd just push on and go straight to the next day's night nappy at my evening shower.

Generally speaking sometime after hour 14, that nappy becomes less and less comfortable.  Sagging, with noticeably cold-and-wet bits, smelly, itchy and often slightly leaky anyway.  By hour 18 I'm dreaming about hot showers and clean nappies wistfully.  If you do more than just wet your nappy, you're going to have a rash.

Your skepticism is in my opinion, very well founded...  There are so many better ways these products could be improved but consumers understand integers.

I wonder how one might devise a test that is a bit more representative?  It would have to account for differing amounts of movement, use in bed, posture etc. Would probably result in something that would be hard to use usefully.

It's far from perfect but I think elements of this could be drawn upon to create a hugely-more-relevant ISO

Indeed.  Other Real World Incontinence videos also have side sleeping and sitting tests. The trouble is we are all different shapes, we tape diapers on with different amounts of snugness, we move in different ways, we sit in different chairs in different postures wearing different clothes and we pee into different parts of the diaper. And even our pee is not standardized. 

(Also if we did have a standardized "side sleeping" test and "press-out" test, it wouldn't take long for a manufacture to game the system and device a diaper that excelled at the tests but not actual real world usage).

Maybe diapers could come with a description more akin to a wine or beer: "ideal for active people who spend a lot of time walking around, but not so great for side sleepers. Wicks better than average and resists clumping. Relatively silent and easy on the nose in all but the warmest weather".

The best advice I would give people is to buy lots of samples of many different diapers and work out what works best for them. Manufacturers should have sample packs available, with clear labeling on the samples so that you don't forget which you are testing (I've had this problem... I once ordered a load of samples from save express which came in a big box and I was unable to work out which some of the samples were!)

For sure they'll try and tilt the table but we've managed to produce standard crash test dummies so I reckon as a species, we could come up with a standarised analogue for having a pee.  I wouldn't want "better" to become the enemy of "best".  Almost any step in this direction would be a vast improvement on the current state 🤣

So now the thread has been high jacked by another topic that has been brought up many of times I say…

 

my diapers shipped !

[abdlwpg]

Please post full pictures of what they look like if you're able to, once you receive them

[munkey]

They have a comic book with each case. These diapees have little boy vibes.
