Brandrup Isotop 3

[MarkW]

Dear All,

I fitted an Isotop 3 to my California SE back in 2015.

When I originally fitted although not a perfect (snug) fit in all areas I would consider it a good fit.

Over time the material seems to have contracted and the fit is now poor (big gaps and the topper is effectively too small.

Has anyone else experienced the same problem with their Isotop 3?

Does anyone know if the material for the Isotop 3 is different to the Isotop 4?


thanks,

Mark

Hi MarkW . I’m pretty sure that the 3 is Gore-Tex and the 4 isn’t as I researched it a while ago .
