Gotta love the Sky Mall on long boring flights.
Offered from Hammacher Schlemmer,
“The gloves exert a gentle compression and are lined with a patented material that facilitates blood flow throughout the hands …”
Now by no means to I endorse this product nor have any proof that their claim is true. But it is certainly worth the $50 to buy a pair and see what’s going on with them. They also have other glove products that could fall into your catagory.
