I have been carrying a Maratac 1AAA flashlight in my pocket for over a year now and wouldn't trade it for anything. It has three brightness settings, is very small and water proof,and is nearly indestructible since it is made of stainless steel. After a year in my pocket with keys,knives,change, and whatever else i carry it is still like new. Not even a scratch on the glass. I made a small para cord fob for it so i can get at it easily. bought it at CountyComm for $30.00.
