Ventile

Ventile, is a registered trademark used to brand a special high-quality woven cotton fabric first developed by scientists at the Shirley Institute in Manchester, England.

Originally created to overcome a shortage of flax used for fire hoses and water buckets, its properties were also useful for pilots' immersion suits,[1] but expensive and leaky if exposed to sweat or oils.

In wet weather the softly spun yarns - within the tight weave - dynamically expand to form an effective barrier against the elements.

[12] A common design feature of some Ventile overgarments uses two separate layers of the textile - with offset seams - to dramatically improve the garment's weatherproof protection.

[11] Alternative branding of the textile, such as Duuton3,[3] is designed to promote less emphasis upon waterproofing and to disassociate itself from the reserve of military, vintage or bushcraft use and position its adoption more favourably amidst travel-wear, general outdoor sports and functional fashion as a practical cotton material with coincidental weatherproof characteristics.
