I've found 18 hour chemical heaters at Wal Mart in the sporting goods
section. I bought a 10-pack for about $7.00.

I've also found that they're more effective if I open them up a half hour or
so before flight while preparing my ship. I carry them in the pockets of my
hoodie and take them out and shake them occasionally. Just before getting
into the glider, I put them into my boots.

Jim...please identify the brand and model of the down booties and chemical
warmers you prefer.I too would like a source for 18 hour stuff.

With your current "dress", down to what outside temperature can you stay
comfortable?

Thanks.

Ben
