Whistle

Whistle, drawn for sports, game and equipment. Useful across equipment and outdoor. It is free, the PNG is transparent, and you can use it commercially without crediting anyone.

Every Whistle detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is a 3D render, on a transparent background, with no mask to draw.

Used alongside other Objects icons it holds its weight visually, so a row of them looks composed rather than assembled.

Common homes for it are product interfaces, feature illustrations, empty states and onboarding screens. Teams in consumer apps, e-commerce platforms and productivity tools tend to use it most. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
