Gecko HYPERFLASH is a homage and retro flashback to the magical "thermochromatic" color-changing apparel of the early 1990's.

  • T-Shirt Changes Color From Purple To Pink at 88 Degrees! (And changes back to purple when it's cold!

Please Note: Hand Print is not part of the design, it is used to showcase what the tee looks like when it is hot. You can make your own hand print while you where it, but it is temporary like invisible ink. Color-Change activates differently every time you where it depending on the temperature of your body.

How To Choose Your Fit & Size

For HYPERFLASH ThermoChromatic Tees

If you've tried our slim fit tees and our classic fit/pigment dyed tees --  the sizing of these is somewhere in between. For the long sleeve shirts, If you like a looser feel/fit, definitely go a size up. If you are taller and like longer sleeves, we recommend you go a size up too. However, if you have shorter arms, or you like a normal/slightly slimmer fit -- go with your true to size.

The sizing of these are slightly different than our normal tees, because with the Thermochromatic dyes, they go through a washing process -- which eliminates 95% of shrinkage prior to purchase. 

Gecko Hawaii HYPERFLASH shirts are heat activated and change color around 80 degrees, which gives it a super rare, "living, breathing, tie dye" feeling. Think of it as "the mood ring" of t-shirts -- but WAAAAAY cooler!

Thermochromatic technology has improved dramatically since the 1990's, but most apparel companies don't make it, because they are afraid to take risks, and it is REALLY expensive to make. However, our fans kept asking since our relaunch, so we are making it happen again!

The shirt is so awesome. Love the artwork. The only thing I would say is the neck line is very low. It doesn't fit that well around the neck, not very snug. But Love your products.


Great Product


I loved everything about them and the memories they bring up for me are priceless, as I lived in Hawaii when this was a huge fade and everyone had to have one. Bought 300 dollars more of the hyper shirts and just got the one y’all made only 80 of! I’m hooked on these shirts.
