Cervical Neck Collar Which Is The Best Air Cervical Traction Collars That Fit Around The Neck?

Which is the best air cervical traction collars that fit around the neck? - cervical neck collar

I'm trying for the cervical traction collar you wear around your neck so that one can have a look and do things and not be stuck in one place. I saw the brown 3-layer beads and blue collar 5 p.m. to 7 a.m.-layer, while pumping the air. Suggestions on what works best, or better, although I do? Thank you in advance for your time ...
