Has anyone here ever tried a cooling vest, or any of the other vest-like or shirt-like things that some MSers use to keep cool in the summer time??

What's a good brand to buy?

What's a good AND CHEAP brand to buy?

What's a good and cheap AND NOT UGLY brand to buy?

I wonder if I can MacGyver something together to use as a cooling vest, that's not going to be ugly. I dont know how to make clothing (yet. Gonna take sewing classes) otherwise I'd attempt to make something that at least wont be as ugly as the cooling vests I've been Googling some today.

Since it's not summer yet, and it's not all that warm where I live right now, I figured I'd start asking about cooling vests now instead of later this spring.
