My surgical Neurologist prescribed an ORT 13100M my use in recovery of fractured vertibre in my neck. A 2 1/2 by 10 inch expandable cloth sleeve came packed in the box with the cervical collar. How is this sleeve used and for what purpose. Thank you very much, Les Calder

After trying numerous ergonomic pillows to help alleviate neck and shoulder pain, this one is by far the best! I have been sleeping with it for about a week now and have had a significant reduction of neck pain, tension headaches, and shoulder pain. Chiropractic Neck Pillow for Extra Support Sunshine Pillows

Hello Les, If you notice the shape of your collar takes on the anatomical contours of your neck when wearing it. The 2 1/2 x 10 inch sleeve that came in the box is a extra synthetic covering to be used over the foam collars, most likely by seperating the end of the cloth and sliding the collar into it. It works as a barrier between the skin of your neck and the actually foam collar for absorption of sweat and dirt. This will keep the actually collar clean and can be taken of and washed periodically.
