2 Pack Replacement Compatible with N30i, Adjustable Strap for N30i and P30i, Great Value Supplies by Medihealer.

Very nice! Design is a tad different from the original, but works flawlessly. Very good fit and secures perfect. Thank you!

Name branded CPaP products are expensive so I look for well rated generics. This back strap is well made and works well on the N30i. I have purchased these several times and have been happy with the purchase.

These work with my cpap headgear, resmed p30i. The Velcro is strong and holds well. I usually replace every 6 months as the fabric and Velcro stretch out. I found this to be the best price at time of purchase.

Great quality strap. Surface is very smooth and slips on head.

Great fit and adjustable. Great quality, I have cleaned them many times

I know this product wasn’t intended for this, but after months of trying different attachments and even making my own version for fixing the Apple Vision Pro’s lack of a proper top band that helps relieving the device’s weight on the front of my head, this was the perfect solution, both aesthetically and functionally. The color looks good along with the gray fabric of the original headband, and it works just perfect. It’s adjustable and comfortable. If you have an Apple Vision Pro, this is the perfect fix for it biggest flaw.

Fit perfectly with the ResMed on top of the head CPAP mask. Comfortable straps I don't even notice when I sleep.

Comfortable and light.
