This is a Fog icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
This icon is three small lines, staggered in an alternating way with half of a crescent moon shape drawn over it. The moon shape begins on the top of the top line and goes down on the right side of the three lines ending on the end of the third line.
