Under Armour Logo History: Evaluating Design Changes
A practical assessment of Under Armour’s interlocking UA mark, how the identity has been refined, and what those changes mean for vector artwork and use.

The logo this history is about
The subject is Under Armour’s interlocking UA monogram and the UNDER ARMOUR wordmark that usually sits with it. Anyone evaluating the brand’s design history is looking at a custom athletic lettermark: a U and an A fused on a shared vertical stem, drawn as a compact, high-contrast symbol for apparel, footwear, equipment and sports marketing. For vector work, the live question is whether a file matches the current official drawing of that fused glyph, in the correct spelling and lockup, with true outline paths that can be sized, coloured and produced.
Origin, construction and meaning
Under Armour began in 1996 under founder Kevin Plank as a performance-apparel company. From early commercial use, the identity that became publicly recognisable is the UA monogram. In construction terms the right upright of the U and the left upright of the A occupy one shared stem, so the mark behaves as a single fused glyph. The counters, the U bowl, the A aperture and the weight of that shared stem have to hold together as one drawing. That join is the feature later vector files either preserve or get wrong.
The legal wordmark uses the spelling ARMOUR. That spelling is part of the company name and of the registered word, and it belongs in any lockup that claims to represent the brand. Substituting ARMOR changes the word and parts company with the identity as used in trade.
The tight join is often read as strength, coverage or a protective shell—an association invited by the name armour—and as one athletic unit rather than two separate initials. That reading is interpretation. This brief does not include an attributable designer statement of intent, so meaning should not be treated as a quoted origin story.
What changed in the design
Evaluating this history is largely an evaluation of application and lockup. The interlocking UA has remained the primary symbol across decades of product and campaign use. Public variation has typically involved how the monogram sits with the wordmark, how colour is applied, and how small-run processes such as embroidery and screen print force a single-colour treatment. Campaign lettering has appeared beside the mark. The core glyph has not been replaced by a different symbol in the way some apparel brands have retired and redrawn their icons.
A year-by-year list of official redraws, named design credits and construction-grid measurements is a gap in the evidence available for this article. Treat product-tag photos, fan files and undated web previews as snapshots of use, not as dated masters. For anyone preparing artwork, the working rule is to match the current official drawing of the UA join and wordmark, including stem weight, overshoot and spacing, rather than averaging older appearances.
| Part of the identity | What the public record supports | What it means for vector artwork |
| Primary symbol | A bold interlocking UA used as the main brand device | Build or check one fused outline; the shared stem is a single geometric relationship |
| Wordmark | UNDER ARMOUR in an athletic all-caps lockup, with the ARMOUR spelling | Keep the word as a separate piece of artwork from the monogram; preserve the spelling |
| Change pattern | Stable monogram with refinements in lockup, colour and application | Prefer a current official drawing over an older scan or a rebuilt lookalike |
| Colour use | High-contrast black, white and red applications in product and marketing | Prepare solid, reversed and single-colour versions from paths, not from a photograph |
| Authorship and dated redraws | Not established here from attributable design records | Leave designer names and stamped redesign years off the file history until a primary record is in hand |
Vector files, previews and the UA join
True vector artwork for this mark is outlined path geometry of the monogram and, where included, the wordmark. A PNG, JPG or on-screen preview is a raster picture of that geometry. An SVG, EPS or AI container can still hold an embedded raster image. The filename and extension record a wrapper, not a proof that the UA join exists as editable paths. When the shared stem is a flattened bitmap inside a vector frame, recolouring, vinyl cutting, embroidery punching and large-format scaling all require a rebuild.
- Confirm the UA is compound path geometry with a clean shared stem, consistent stroke weight and intact counters.
- Inspect for embedded raster images and for live stroke settings that will shift the join when scaled.
- Keep the monogram and the wordmark as distinct objects so lockups can be set to the official arrangement.
- Prepare a solid one-colour version; apparel and print processes often need the mark without grey or photographic fill.
- Compare stem thickness, the U bowl and the A aperture against current official merchandise rather than against an undated download.
Downloading, modifying and using the mark
The UA monogram and the UNDER ARMOUR word are protected trademarks. A file you can open still only supplies artwork. Permission to use, modify, recolour, combine with other lettering, or apply the mark to goods and services sits with the rights holder and is a separate legal question from access to a drawing. Commercial merchandising, altered versions and any use that suggests sponsorship or affiliation generally require a licence or other authorisation. Study of the construction for evaluation is a different act from releasing a rebuilt or recoloured file as a substitute original.
Gaps in the public record used here
Designer credit for the original monogram, an official sequence of redraw dates, outline-stroke values, clear-space rules, minimum sizes and specified colour formulas are not stated in the evidence on hand. Those figures belong in brand guidelines and should be taken from the rights holder when a production file is required. Visual comments on how the join reads as armour or as a single athletic unit remain interpretation. Until attributable records fill those gaps, evaluation of design change should stay on the stable UA construction, the ARMOUR spelling, lockup and colour application, and on whether a given file is true vector path artwork of the current official mark.
