Input:
Question: My neck is 13.5" circumference & about 3.5" from from collar to below chin.  Will it fit me?  Need support + comfort on plane.
Document: Nor does it work like a pillow. The collar is u-shaped with a fabric extension that wraps around the back of the neck and secures with velcro. The rigid section of the collar is 3.5 inches high on the sides and 3 inches under the chin. The rigidity is provided by a plastic insert sandwiched between foam.
This is my second brace. The first one I left on a plane and is now someone elses gain. These braces are fantastic. Much better that a neck pillow. They even come with a plastic carry case to pack into your carry-on bag. I'm 6' 3" 215 lbs. and it fit my neck just fine due to the velcro adjustment.
Nothing is the same as being in your own bed, but after a year, I still use this collar on the plane and bus. It provides support and is remarkably sturdy. It is small enough to fit in a backpack, so you will actually pack it in your carry-on. I liked not having to inflate it (I didn't want to put my mouth on a valve brushing past surfaces in an airplane). You can wash the case separately.
Said the collar is comfortable - not too tall & not too tight (he wears a 16.5&#34; collar & IMO has an average length neck); did not sweat in it; the material did not soil easily; the velcro attaches firmly; nothing chafes anywhere; the collar did not collapse anywhere. He was unable to read with it on; and he had to angle his Bose headset (the larger style) a certain way in order for them to fit & cancel noise correctly.
This product helps stabilize the neck while traveling, but it doesn't completely support the neck for restful sleep. I still need to use a small travel pillow in order to get some decent sleep while flying. I like that while moving though airports, I can wrap the collar around my arm instead of having to put it in my luggage or carry it.
The idea behind this is great but they need to make an oversized and/or overfilled one for those with longer necks. Even though I've never thought of my neck as being particularly long, after using this on a plane for a few minutes, I noticed that my head was sagging past a comfortable position.
I have an Embrace Sleep collar for about 3 years. I use it for long flights (4 to 15 hours). It works great. It stops your head from rocking and you can sleep well. It also does not push your head forward like a bucky pillow. I have a bucky pillow and have even brought full size pillows onto planes. This is my preferred method of sleeping on a plane now. It does NOT use up a lot of space.
I've tried a few different &#34;C&#34; shaped neck-support pillows while traveling, and while they give some support, my head would always fall forward when I fell asleep. This collar really helps with that problem and makes it much easier to sleep on a plane or train while upright. I would recommend it.
I bought the collar specifically for sleeping during flights, but may use it during car travel as well. I've tried blow up U shaped pillows, and also the ones with the beaded type filling, but neither worked. I realized I needed something that would go around the front of me, not just the sides, since often my head would drop forward while sleeping. I needed something stiff enough to support my head in all directions, but also soft enough to be comfortable on my chin/jawline.
I tried a over the counter neck brace for sleeping on long plane trips but it was too bulky and hard to carry in carry on luggage. This gem is compact and provides great support to my neck and head. Easy to sleep in.
Answer: To be perfectly honest with you, I purchased this for my 84yr. old mother, to help keep her neck from hurting when she would fall asleep watching the t.v. She HATED IT. My daughter used it on a trip to Hawaii, and could not use it because it was VERY uncomfortable, she felt like it was strangling her, and had to take it off.  Your neck size sounds about like her neck size, same as mine. I would say, save your money and just use a small pillow. I could have gotten my money back, but would have had to pay for the shipping, and had paid enough already. That's "our" honest opinion, hope it helps.
