What is the best fabric for a canvas bell tent?

Aside from Homecamp we also own an outdoor events business - Under Sky which uses bell tents for accommodation, This has given us a unique opportunity to continually test our tents and also many other bell tent manufacturers side by side. Over the years we have settled on a custom-manufactured canvas made with a cotton-polyester blend. This fabric has high tensile strength and an excellent strength-to-weight ratio, which means we can produce canvas at lighter weights that are still much stronger than 100% cotton at comparable weights. This means that this canvas will perform better in high tension situations - i.e. continuously stormy weather - perfect for campers or businesses who keep their tents up for extended periods of time.  

Being a weave our canvas still ‘breathes’ keeping moisture out of the tent and preventing condensation which is a common issue with synthetic tents. Our canvas is treated to be UV stable and mould resistant. In our experience, Cotton/Poly is much less prone to mould and much easier to clean than 100% cotton.
