This unit add-on is another way to secure your unit without the need for clips and/or combs. The elastic band is best added by sending us a measurement of your head from ear-to-ear (the back of your head, near your hair line), but can still by added with an estimate OR by using our one-size-fit-all option. 
 
Elastic bands are great for ensuring a snug fit! We suggest ordering our signature DreamBand along with your unit for an even more secure fit.
