i thought those shirts were awesome. i got mine at jcpenney

These are soo cool. I had one when I was a kid.

These were cool in theory, but sort of embarassing to wear...especially as a high school student, where EVERYTHING embarasses you! The arm pits were always heat activated, so people knew you were sweating. Also, if you washed and dried them too often, the colors were permanently mixed, like an ugly tie dye shirt.

I wish they still sold Hypercolor shirts. That was such an awesome idea!

Hyper Color was the Sh--! they need to come back why did all the cool stuff leave us??

I never owned one, but I soooo wanted one. I used to breath on them in the department stores. lol.

I owed a green one! Wow, the memories. My mom always washed it in cold water so it never faded and always changed colours!

I had a XL peach one that turned yellow I think? When it stopped changing colors I cut the bottom off to make a short shirt to layer over my long tank tops, remember THAT style?

I remember these, wish I could still get one, wish they made socks and other stuff of that to..

My best friend in elementary school had one of these and I was SO jealous.

I had a purple one that turned pink... except... there were two particular spots that ALWAYS turned pink, and it wasn't the armpits... so embarrassing...

There was also one that had a man on the front with jeans, sunglasses and a jacket on and he stripped down to a t-shirt and boxers when the "hyper color"-ness went into effect

I still have mine!!!! It changes from a light pink to a light blue.

Found these on E-bay!!!

I loved these shirts

omg! i remember those. i was so small and so amazed

I fell prey to a lot of trends but never this one. I thought they were cheesy and uncool from the get go (surprisingly). All of the kids in school seemed to have them though.

I still have mine after 17yrs, it still works as good as the day I got it. I like to pull it out every now and again to show my younger friends for kicks.

I had a purple one that turned pink. It was so cool. We thought it was funny to put hand prints on our tits and tease the guys lol

i remember all the other girls tits changing colour coz i was an ironing board it never happened to me i was waiting for the day but it never came gutted.

I remember these! They also had HC shorts! We would put handprints on our boobs & butts & va jay jay's!

One of my friend's in High School had a couple of these t-shirts. I thought they were pretty cool, until she wore a pair of shorts and lets just say they really worked. I couldn't stop laughing...not so cool for shorts, if the t-shirt armpits and heat make you embarrassed.

They still do sell them, here in NY: http://bigdropnyc.com/shop/pc/viewCategories.asp?idCategory=212

I had a pink shirt that turned purple. I wish I still had it. :(

I never did own one of these but they were fun to play with on other people. I remember they ended up looking kind of washed out/faded pretty quickly. Still, definitely a time warp item.

I had the purple 1 on the left. I was a small awkward underdeveloped girl so I never had the warm spots or hand prints on the boobs. However in the lunch line people would splash cool water from the lunch trays on HyperColor shirts and it would make dark spots all over the shirt. Then people would lick their fingers and smudge the shirt. A few years later, when they weren't cool anymore and began to sell them a cheapy stores, I gave the shirt to the Goodwill. Even with the abuse, I liked my shirt.

I remember these! Never had one but always wanted one! Everyone at school used to wear them.

Oh yes, Hypercolors!!!! If you had this shirt you had to get ready for your friends to try blowing their hot breath on your shirt or splash water on you or while you sweat in your pits the colors would change and your peers would laugh at you....a shirt I did not own but was greatful to my parents after seeing my friends suffer after just days of purchasing them.

These shirts were so much fun!! I never forgave my sister-in-law for ruining mine when she put it in the dryer. It got "stuck" and wouldn't change any more. It went from blue to purple. I loved it, and if I find another one, I'm so getting it. I would like to get one that goes from blue to green next time.

San Diego Avenue in Old Town San Diego has something similar

These were fun to wear. I had a blue one myself. Sadly they didn't last long due to the fact that they were easily damaged.

I still own 3 of these shirts. One is aqua and yellow, and the yellow turns gray when cool, aqua gets lighter when warm. One is purple when cool, and turns blue when warm. The third is blue when cool, and pink when warm. I have owned these shirts since they were new. The only way to wash them is by hand, no wringing,hang on a hanger, and allow to drip dry. Do not hang on a line outside in the sun.My shirts have been through a lot, and I will continue to enjoy them for many more years. I always get compliments on them every time I wear one.

Had the whole freakin hyper color outfit! Longsleve shirt and PANTS! During the winter!!!! The only time it was safe to wear was in a very warm room!

This website looks like it's from the 8-'s

I loved my Hypercolor shirts when I was younger, went online and found "Bodyfaders". Now my kids wear them. My oldest is in middle school all his friends want one now and the teachers remember when they use to wear them. Science class was fun for both of them with everyone trying to figure out how the shirts worked. They also sell fabric, my youngest wants me to make a blanket out of it.

I have a couple of these around. I likes looking at the girls who were wearing them... usually changed color in the general 'chest' area. Very attractive!

I found another Hypercolor shirt in Goodwill just before Christmas. My husband wanted to go in there, so I went to the men's clothing and looked thru the T-shirts. And there it was. A blue one. It changes to mint green when splashed with cold water. I paid 2 dollars for it. It works perfectly. Now I have 4 of them.

I think I wore some of them!

Paha..I just found my sweatshirt from when I was in 9th grade...(1988) shuu.....now, my 17 year old Senior wants to rock it! Like they say , History reapeats itself!

i still got my purple/pink shirt and my hyper colour shorts with pocets !!

Radiate Athletics sells a line of athletic wear that is "heat-activated" just like HC clothes were.

Had 4 of the Shirts when I was a teenager. Loved them. Especially loved the shorts for the girls, you could tell whenever they were feeling the mood so to speak. Good times.

My best friend loved her shirt so much, until she dropped ketchup down the front, which made a long stripe of color stay permanently
