Just one look around the BJC at any point during THON weekend will make you realize you can never have enough THON apparel. With what seems like an endless combination of designs, materials, and articles of clothing, it seems like you could easily fill a whole wardrobe with just THON merch.

So of course, this year THON introduced two new pieces of clothing, guaranteed to have you running to the nearest ATM. Both of the shirt variety, you can now buy a glow in the dark THON logo shirt and a “sweat-tech” shirt that changes when it gets wet.

The more unique of the two, the sweat-tech shirts look like normal shirts when dry, with nothing on the back side. But get these shirts wet, and you reveal the THON logo, showing everyone just how FTK you are — perfect for sneakily showing your THON pride during and workout or water-related activities. The shirts are also incredibly soft and comfortable, made of an extremely breathable material. And for just $20, the innovative shirts feel like a bargain, especially considering how expensive THON’s food is.

The glow in the dark shirts, shown below, feature the THON 2017 logo on the front, and were given to all the dancers. You can pick one up for yourself at the THON merchandise store, also for $20.

According to the Merchandise captain working the booth at the time, both shirts have sold extremely well over the weekend, but shirts currently remain in all sizes, so head over to the merchandise booth to claim yours before it’s too late.
