<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Remix style is ideal for designs that require a distinct look without overwhelming the overall aesthetic.&nbsp;All Flex Remix icons are designed on a 14px grid with a mix of outlined and filled shapes.</p>

**Summary**: Flex's graphic identity sub-style — outlined paths mixed with opaque solid fills on organic curved forms, creating a visually complex, flowing graphic presence for brand and editorial use. The flowing construction feels organic and designed rather than computed, with the fill-plus-line mix adding visual complexity while retaining warmth through shape language. The tone signals "flow and graphic intelligence" — a more characterful version of the organic aesthetic for contexts beyond standard UI chrome. Best for brand identity components, marketing illustrations, feature highlight sections, and creative campaigns where icons need graphic presence at medium to large sizes.

### Emotional Scores

Flex Remix is one of the warmer sub-styles in the catalog — monochrome, but flowing fill-and-outline mix retains natural warmth through its shape language. It is one of the more human-feeling sub-styles in the catalog on softness — partial fills within flowing construction add definition without hardness. It is one of the friendlier sub-styles in the catalog — the organic graphic mix is distinctive and considered, with only mild formality. It is one of the more playful sub-styles in the catalog in a nuanced way — the flowing organic form creates considered visual complexity rather than outright play. On its human↔mechanical character, it is one of the most human-feeling sub-styles in the catalog — the flowing construction feels organic and designed, not computed.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Syne — display-weight geometric with flowing aesthetic that matches Flex Remix's organic graphic presence
- **Alternative**: Plus Jakarta Sans Bold — humanist weight at display level
- **Body**: Outfit Regular or DM Sans
- **Avoid**: Cold rational grotesque; warm hand-drawn fonts


<p>Flex is a fluid icon family inspired by nature’s curves. It favors smooth, flowing forms. More organic than Core and subtler than the chunky Plump. Read about the <a href="https://blog.streamlinehq.com/flex/" rel="noopener noreferrer" target="_blank">design process</a>.</p>
