If you’re dressed up as Santa or wearing a mascot costume, we don’t need to tell you that it can get hot. Even if you’re wearing it at night or indoors, the lack of ventilation can take a toll. And though your mascot costume may always be smiling, you may be suffering on the inside. A Glacier Tek vest can keep you comfortable for up to 2½ hours while you pump up the crowd or make a child’s day.
