I couldn't make through the spring and summer without my cooling vest. I've had one since 2001 and I love it. Yes, when I wear it I look like I have put on at least 10 pounds, but I'm comfortable.

Mine has the chemical pack inserts that freeze solid in 20 minutes, last about 4 hours and refreeze in 20 minutes. They freeze solid at only 64 degrees. Developed by NASA. Honestly, I couldn't even get through church on Sunday without it. I really need a new one since I've gained substantial weight since I first bought it.

Well worth the investment. I think you get to a point with these diseases and life in general, who cares what you look like as long as you're comfortable.
