Great for short 2-5 hour flights but not Longer flights

I have mixed feelings about this neck pillow Read the reviews that led me to buy it I purchased the XL version for $10 more fir the past 60days I did 8 flights over 14 hours each and 10 between 2-5 hours each On the long flight I managed to sleep a good 7 hours and in all cases I ended up sweating needing to get the pillow washed after a round trip as a stiff or sour neck but on the up side on short flights It worked perfectly managed to sleep easy and no side effects
