Easy for kids to use
Size: 5 Ounce (Pack of 2)
My son uses this when he's outside because constantly gets bites. He's 7 and can spray it himself and no bites when he uses it. Would highly recommend. Does linger in the air after so I don't recommend using in the garage

Works well to prevent sunburn and stays on while working.
Size: 6 Ounce (Pack of 1), Style: Spray
This sunscreen is great! I've worked outside in New Mexico sun for the past few years and this is a life saver. Goes on evenly and doesn't come off while I'm working in the heat.
