Good stuff - I only half-cocoon with the wrap because I can't sleep so well completely under the blanket. I might try one of those head pieces after reading the article - I'm usually on the road for a while so I fight hard not to pack around extra gear, but if I'm doing a lot of flights in a short period it's probably worth the $10 just to see if there's a benefit. I'm flying tomorrow but it's only a two hour flight, I might try next time I do a long haul - cheers for the recommendations.
