This Sign Out icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
This icon is a very line line drawn in a circle with a small portion left blank on the right hand side. Inside of this empty portion is an arrow that is pointing towards the right. It starts in the center of the circle and ends right at its edge.
