What this site is
Yottatable is two things sharing one data layer. The first is a long-form publication covering equipment science, long-distance routes and access rules, and the business of outdoor brands. The second is a set of 12 working planning calculators. They are the same project: the research that produces an article about insulation also produces the layering advisor, and the numbers in a route piece also feed the hiking-time calculator.
The site currently holds 30 articles totalling roughly 21 thousand words, 103 cited references and 61 catalogued equipment records. Every equipment item named in an article has its own specification page. Every article has a reference list. Every tool has a method note.
Editorial principles
We cite, or we say we cannot
Every data point in a Yottatable article is traceable to a named publication, standard or manufacturer document listed in that article's reference section. Where a figure could not be verified, we write that instead of presenting an estimate as a measurement. Ambiguity is honest; false precision is not.
We buy at retail
Long-form equipment testing uses samples purchased at full price from retail channels rather than supplied by manufacturers. This costs more and takes longer, and it removes the possibility that a brand quietly selects the sample we test. Where we do accept manufacturer information — datasheets, declared weights — we label it as such.
We publish the method, not just the result
Our calculators name the formula they implement and list the standards behind it. Our articles carry a method note describing sample size, protocols and instruments. Anyone who disagrees with a conclusion should be able to see exactly how we reached it and reproduce the step that failed.
We state our limits first
Every tool page lists what its model cannot do. Wind chill overstates the effect on clothed surfaces; the weight-based sweat-rate method carries meaningful error; Tobler's function has no term for snow. We treat those admissions as part of the product, not caveats to bury.
We take no payment for coverage
Yottatable does not accept payment, gifts, travel or product placement in exchange for coverage. There are no sponsored rankings on this site. If that ever changes, the change will be disclosed at the top of the affected page, not in a footer.
We correct in public
Articles carry a first publication date and a revision date. Substantive corrections are logged with the date and the nature of the change. Silent editing is a form of misinformation, and we do not do it.
How we test
- Field trial: a minimum of twenty days of use in the conditions the product is designed for, documented with dates, locations and observed temperatures.
- Lab measurement: weight and dimensions verified on calibrated scales rather than taken from the datasheet, and quoted alongside the manufacturer figure.
- Durability: where relevant, standardised cycling — laundry for textiles, freezer cycling for laminates — with performance measured at intervals rather than at a single endpoint.
- Price tracking: retail prices sampled across at least two markets and reported as a band, never as a single authoritative number.
Corrections & contact
If you believe a figure on this site is wrong, tell us which article, which sentence and what the correct value should be with a source. Verified corrections are applied and logged with a revision date. Manufacturers wishing to challenge a measurement are welcome to do so in writing, and should expect that we will ask for their test protocol before changing anything.

Who writes this
A small desk, deliberately. Each contributor is responsible for the accuracy of the figures in their own pieces and is credited with their role on every article.
