Do Hypercolor t shirts expire? Seeing some on ebay but none say whether they are still heat sensitive.
Thermochromic leuco dyes tend to be fairly long-lived, provided they are shielded from sunlight (UV radiation) and high heat.
If the shirt is worn outdoors and put through the dryer, it will lose more and more of its ability to change color over time. Since everyone wore them outside and washed them, they may not have much color change left if buying a second hand garment, tho NOS items may be good.
You can buy new thermochromic t-shirts from Bodyfaders - tho it won't have the sweet '90s-cachet "Hypercolor" logo on 'em.

Yep, they definitely stop working/work less well after a while of normal use.

I had some back in the day. Putting them in the clothes dryer a few times totally nuked them. So yes, they can "expire".

I had one that was pink-to-white when I bought it, and at some point changed to purple-to-green, except for a grease spot that stayed the original color. Not terribly long after that, it all faded to old-T-shirt gray. I'd imagine that if the photos show the original "cold" color and it's still fairly bright, it probably has some juice left. A never-worn shirt would have better luck over time.

My impression is that heat (washing in hot water, ironing, drying in the dryer) was the most common way to damage them. A vintage clothing dealer I know jokes about having a dozen of them socked away in her cold, dark chest freezer.

American apparel sells new ones(example)
I wouldn't expect an old one to still work satisfactorily, as I've definitely heard about the effect failing over time.
