Medihealer 2Packs Replacement Strap with Clips, 2Packs Replacement Strap(L),Soft Strap with Stronger Elasticity

Make sure to choose the correct size. The fit is better, it is more comfortable and when you choose a size over "One size fits all", and the better cost. This is a better deal.

These were a good replacement for the f20 pair that I used to have and they don't hurt my head as they seem to be extra cushioning

This product is the best

There's nothing I don't like about this headband. Got here fast and the fit is very good

Velcro is better stays in place awesome.Shape is great fit is better, and more comfortable.

Work well for a couple months. The headgear will stretch out and the velcro will start slipping too. They are inexpensive so I'll still keep buying them, until I can find a better alternative.

these are amazingly better than the original ones i was using — thank you!

Using Resmed with the airfit20. Very easy to attach and very much like the original product. It's been several months, and the Velcro still holds without coming loose while sleeping. Absolutely no issues.
