From last summer, here is a an exchange on this subject from CPn Help.org that may help (http://www.CPn Help.org/life_on_a_good_day
From Cypriane (me):
"Willow, It's wonderful that you are feeling well enough to type more and plan your lapidary projects. Now, about the heat...go to http://msolutions.org
as a good source for cooling vests. Spotty couldn't work at his job (their A/C doesn't keep up well enough) or go anywhere in the summer if he didn't have his to rely on. If you can swing it, I would also order extra cooling packs. He uses the Phase Change type, but the Kool Max looks like a good alternative and costs less. I'm not exaggerating---this makes a huge difference in our lives. Last night when we left work the temp was 107, but thank goodness it had cooled down to 106 by the time we got home! Even though we have A/C in the car, just the going out and coming in for any trip during the summer here is enough to cause heat-related MS problems. It's like walking through a convection oven every time we go outside after about 9 a.m. Also, the humidity here is much higher than out west in the dryer regions...that makes it alot worse. Please do this for yourself as soon as possible. A funny note on this...Spotty's vest is blue, and every time we go shopping the store's customers think he works there and ask him all sorts of questions and to do all sorts of things.

followed by something even better from Wiggy:
"Willow and Cypriane,
I have a cooling vest I can not live without and I got it here http://www.msaa.com/programs/cooling.html
. I have to return it when I recover - they give them out to people that need them. Its very nice. They also sent me neck, arm, feet coolers but I only really use vest as it takes me so long to get all of it on and I look like I am going on a space mission. I hope I remember to send it back when I recover as I had to ask my husband "who sent me that vest" as I could not remember.
Everyone with MS should get one if they have problems with heat - I went to beach with mine on and I lasted 2 hours."
Best wishes and stay cool, Joyce
