Flex Duo

<p>Flex is a fluid icon family inspired by nature's curves. The Solid variant features smooth, filled shapes with rounded edges for a friendly, organic aesthetic.</p>

**Summary**: Flex's impact sub-style — opaque fills on fluid organic silhouettes, providing strong visual presence while preserving the flowing, nature-inspired quality that distinguishes Flex from geometric solid sets. Organic silhouette edges soften the fill hardness, keeping the register modern and grounded rather than authoritative or cold. The tone signals organic groundedness: "we are grounded and solid without being rigid." Best for active and selected states paired with Flex Line, feature callouts in lifestyle and consumer apps, photography-heavy layouts where organic icon silhouettes complement imagery, and navigation where Flex Line is too fragile at small sizes.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Opaque fill with transparent cutouts — background visible through cutout areas |
| Corner treatment | Smooth rounded organic silhouettes — shapes flow rather than contain |
| Color | Monochrome |

### Emotional Scores

Flex Solid is one of the friendlier sub-styles in the catalog in a grounded way — solid black fills on organic silhouettes read as modern and natural, with the warmth of flowing shapes partially offsetting the coldness of a black fill. It is somewhat soft — solid fills add visual weight, but organic silhouette edges soften the overall reading. It is somewhat friendly — organic solid silhouettes are modern and considered, landing between warmly approachable and formal. It is somewhat playful in a restrained sense — the organic quality reads as natural rather than playful, with the solid fill giving authority without severity. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the catalog — organic silhouettes read as natural forms, and the fill does not mechanise them.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Plus Jakarta Sans SemiBold — weight-appropriate for solid fills while retaining humanist warmth
- **Alternative**: Outfit SemiBold — modern, clean, compatible with organic silhouettes
- **Body**: Inter Regular or Mulish
- **Avoid**: Heavy grotesque display at maximum weight — overwhelms organic solid silhouettes


<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>
