Drainage slots at regular intervals are especially important on trailing edges. For non breathing materials we build in baffled ventilation pockets.

Designing a cover to perform all tasks is virtually impossible: after all an outdoor all-weather cover cannot be light weight and easy to stow for touring; likewise a hanger cover cannot be expected to keep out driving rain, snow and heavy winds. Categorizing a covers use is the only way to achieve a satisfactory conclusion
Easy to live with: a cover has to last not just one but several seasons if not more. To achieve this is must be serviceable; clips get broken, velcro gets tired, fabrics get mold or mildew, general abrasion takes place. All these problems have to be addressed.
Fit is so important, Fashion models look great because their clothes are cut to accentuate their shapes. Your Aeroplane is no different - they have a great shape that needs to have a close fit, a flapping sagging cover will let in weather and abrade your airframe.
Ventilation is vital to the wellbeing of an airframe, when ambient moisture levels are high moisture gets into and under a cover - especially in a hanger; so built in circulation - even better the use of a breathable fabric ensures a dry surface.
Sun damage is the main enemy of any cover; UV will eventually destroy a cover no matter how good it is. Some of the more expensive modern materials are worth the extra outlay - as they will outperform the more traditional fabrics by a good factor.
We use only the best materials that are fit for purpose - Threads are one such item; these threads are guaranteed to last the lifetime of the application they are in. So the threads will not break down or fade being made from ePTFE.
Seams are designed to run with the direction of gravity - this ensures water will run over and off the seam rather than onto and into the seam as this would lead to eventual penetration.
