Every product listed in Under Armour's live catalogue is retrieved and its stated fibre composition read individually, from the Under Armour product page, Under Armour's own product data and its material labels. A fibre percentage for Under Armour is published only when 100% of the Under Armour catalogue has been read. Items Under Armour sells that carry no clothing textile, such as gift cards, packaging, jewellery and homeware, are excluded from the percentage rather than counted as a pass or a fail.

Not recorded (4,178): These products carry no fibre composition the brand publishes anywhere we can read. They are counted in the catalogue total but excluded from the fibre percentage, and linked so you can check them yourself.

Excluded (346): These are the items Under Armour sells that carry no clothing textile to rate: gift cards, packaging and returns kits, jewellery, homeware, toys, body care and checkout line items. Under Armour's fibre percentage leaves them out rather than counting them as a pass or a fail.
