Great there was no need to replace the frame, it is still sound, but the cover replacement made it all look so much cleaner.

They work very well and are very soft. They can be a little tricky to get on the frame initially, but worth the effort.

These sleeves are a game-changer for comfort! They add a lovely soft layer between the frame and my skin, eliminating all red marks and pressure points.

An inexpensive upgrade that makes my F20 feel like a new, premium mask. Highly recommend for anyone who experiences discomfort or marks from the standard frame.

Simple to fit and make a huge difference. They prevent leaks caused by skin oils on the frame and make the mask feel much more comfortable all night.
