Disclaimer, Safety & Health Notice

All content published on Yottatable — including articles, gear records, tools, references and recommendations — is provided for general information only. It is not professional advice in any field, including but not limited to medicine, nutrition, fitness, mountaineering instruction, avalanche forecasting, law, finance or tax. You should consult a qualified professional in the relevant field before acting on anything you read here.

Outdoor activity carries inherent risk of injury, illness and death that cannot be eliminated. Conditions change, equipment fails, individuals respond differently to altitude, weather, exertion and cold, and no information source can substitute for personal training, judgement, local knowledge and conservative decision-making.

Where any article describes a specific objective (a summit, a route, a body of water, a hut booking), the description is not an invitation to attempt that objective. It is a research aid for readers who already have the experience and qualifications necessary to make their own decisions.

Our long-form equipment testing uses samples purchased at retail, tested over documented periods in the conditions the product is designed for. The results apply to the specific sample we tested, not necessarily to every unit of that product line. Manufacturing variation is real; warranty handling, retailer returns and product recalls can change the product you actually receive.

A score, verdict or recommendation on this site reflects our testing experience. It is not an endorsement, a guarantee, or a warranty. Use it as one input among several before you spend money.

Every calculator on this site implements a named published method and applies a simplified model. Outputs are estimates, not measurements. Each tool page lists the published sources behind its formula and the assumptions it makes. Where the underlying science has a wide error range, the tool discloses that range rather than hiding it behind a single confident figure.

Specifications published in our gear records (weight, dimensions, materials, claimed performance) are taken from manufacturer datasheets at the time of writing and are cross-checked against independent lab measurements where available. Manufacturer specifications can change without notice. Retail prices are sampled at the time of writing and can change; the prices shown in our gear records should be treated as a snapshot, not as an offer.

Route descriptions, permit requirements, booking windows, transport schedules and access rules change. A regulator's policy that was current when we wrote an article may have changed by the time you read it. Verify route conditions, weather, closures and permit requirements with the relevant land manager and your country's travel advisory before relying on anything published here.

Yottatable links to external websites for sourcing and reader convenience. We do not control those sites and we are not responsible for their content, accuracy or availability. Following an external link is at your own risk.

References to specific products, brands, services or routes on this site do not constitute endorsement unless explicitly stated. Inclusion in a gear record, an article, a comparison or a calculator result is a description, not a recommendation.

To the maximum extent permitted by applicable law, we exclude all liability for any loss or damage arising from your use of, or reliance on, the information published on this site. Nothing in this disclaimer excludes or limits any liability that cannot be excluded or limited under the law of your country of residence.

If you spot something on this site that you believe is unsafe or inaccurate, contact [email protected]. We take safety-related corrections seriously and prioritise them.
