Review on DMI Soft Foam Cervical Collar Neck Support Brace - Extra Large Size, 2 1/2 Inch Width - White Color by Heather Brown

My neck is 13 inches. Collar size seventeen inches. But it barely fits around my neck. The locking strap is an inch and a half so not much to secure the collar. The two and a half inch measurement is somewhat misleading. The collar is sized at the clasp (where the two ends meet) but is three and three-quarters of an inch elsewhere. I bought a collar for sleeping and I think it will work for this purpose. But if you want a real collar that fits and supports, this is not it. You have to spend a little more to get real support.
