This is a pretty damn smart idea.
Sell these at a fest, and the kids can jam them full of merch. Trapped Under Ice merch, of course.
These were sold at United Blood Fest in 2009. Smart move.
After the fest, not sure where this would come in handy though. Maybe if you needed to carry a sweatshirt to the gym, or maybe after a good game of hoops. Steb will shut you down so why bother even showing up?
Only 50 made. Good times.
