I purchased and tested some of
these
last week. The nitrite coating was thin and the gloves didn't feel like gloves.
I purchase another brand first at Hone Depot for $1.98/pair, but they were a one
size fits all (so didn't fit as well as the ones linked to above) and the nitrite
was thicker.

I wear extra large gloves normally (fingerless bike gloves, or football receiver
gloves) but the large size fit me best in these gloves.

I'm looking forward flying more with these. You can find them
here
also.
