Caravan Cover Shop advertises various brand-name products which are constructed using 'Oxford Polyester' material, along with products which use 'Polypropylene'.

Polyester

Brand name products that use Polyester include:

- Aussie - 600D Oxford Polyester (entire cover)

- Kaiser - 300D Oxford Polyester (entire cover)

- Kaiser 'Durapoly' - 600D Oxford Polyester (entire cover)

- Camec - 300D Oxford Polyester (roof section only)

- Prestige - 300D Oxford Polyester (roof section only)

As suggested in the above-mentioned article, it is also the opinion of Caravan Cover Shop that Oxford Polyester is a more suitable and heavier duty fabric which is better suited to Australia's diverse and often harsh climate.

Oxford Polyester is typically used in the making of high quality boat covers and shade sails, and of course it is ideal for Caravan covers.

The covers on this site which offer Oxford Polyester construction have been treated for UV exposure, and also polyurethane-treated to ensure they are highly water-resistant.

Oxford Polyester is a 'breathable' fabric, offering resistance to the build-up of mould and mildew. It is also a 'rip-stop' fabric which is more resistant to tearing.

Polypropylene

Brand name products on this site made using Polypropylene include:

ADCO / Camec / Prestige / Samson

Polypropylene covers typically offer multiple layers, either three or four depending upon the brand, which are reported to offer additional protection.

Special Note: In the case of the ADCO brand, these covers are constructed using a mix of materials, i.e. 4-ply Polypropylene for the side walls, and quality Olefin HD® material for the Roof and front sloping panel.
