Affiliate Disclosure

Amazon Associate

As an Amazon Associate I earn from qualifying purchases. HydrateWise uses the tag bendickman-21 and may use Amazon OneLink. A qualifying purchase may earn a commission at no extra cost to you.

How products are selected

A product is included only where it helps translate the page’s decision into practical equipment—for example a known bottle capacity, a repeatable scale for a sweat test or a carrying system for a supported long run. Listings must be live and have an Amazon rating of at least 4.5 when manually checked. Relevance, stated capacity, rating volume and obvious limitations are considered; price tiers and bestseller claims are not used as shortcuts.

HydrateWise does not claim hands-on testing unless a page explicitly documents it. Customer ratings describe the Amazon listing, not a HydrateWise score or medical endorsement.

Review cycle

Each product record stores the date on which its listing and rating were checked. Development tooling flags records older than 120 days for manual review. Redirected, unavailable, weakly rated or poorly matched products are updated or removed; prices and stock are not stored because they change frequently.

Editorial independence

Paid links do not change calculator results, safety cautions or editorial conclusions and do not make a product medically suitable. Safety-focused pages about dehydration or overdrinking do not carry affiliate panels. Check current product details, capacity, fit, event rules and manufacturer instructions before buying.

How links are labelled

Affiliate panels are marked “Advertisement · paid links”. Links use sponsored and nofollow attributes, and calls to action direct readers to check the current Amazon UK listing rather than making “best” or “must-have” claims.
