I bought the Trtl last year and used it for some domestic flights, a trip to Italy and a trip to Cambodia. I travel light, so it needed to be worth carrying it. The design is almost like a soft, thin fleece scarf, but it has a formed plastic piece that cradles your head.
After using it on my trips, I really liked it. I’m a stomach sleeper, so sleeping with my head tilted back on the seat is uncomfortable and unnatural for me to sleep. I can get by with short spurts leaning on my husband’s shoulder, but my trip to Italy was solo travel. Also, I was attending a music concert the first night I arrived at Italy, so I needed some quality sleep on the plane.
I liked that I could position my head to either lean slightly forward or to the side. The wrap was a little warm, but it reminded me of having a blanket snuggled up to my neck, so it wasn’t a negative for me. I actually slept! ...not snoozed, on both international flights, so I’m giving it two thumbs up.
I just stored my Trtl in the open pocket of my lightweight LL Bean daypack during the rest of my trip.
