Shedrain VortexVent

About the Entry

Shedrain has an ongoing commitment into the specialist research of adverse weather conditions, Haythornthwaite Design translated their insights into a challenging design brief for rethinking the archetypal umbrella.

The team developed and tested innovative advancements in frame and canopy design, resulting in the VortexVent – an umbrella to outlast the storm.

Features & Benefits


Anti-Inversion-Strut (AIS)

An innovative Anti-Inversion-Strut (AIS) system mechanically strengthens the ribs of the frame, limiting flex and ultimately preventing the canopy from inverting in high winds.

The unique contours of the AIS slide together with precision allowing for a compact and streamlined collapsed profile.

Pressure Release Venting

The VortexVent canopy is a reinterpretation of a typical single layer canopy and is comprised of two layers. The base layer is vented to quickly release build up of wind pressure through a full 360┬░, while a taught outer layer covers the vents and maintains a watertight interior.

Elastic Vent Straps

The 2-ply canopy layers are connected by elastic vent straps, this allows for an enhanced responsiveness and capability to yield to adverse weather conditions whilst ensuring the canopy can reliably retain its form and maintain protection from the rain.

Energy Absorbing Shock

Energy Absorbing Shocks (EAS) increase the resilience and life expectancy of this umbrella by safely dissipating wind forces between the Anti-Inversion Struts and joints of the canopy frame.

Tip Tensioning System

The outer canopy is connected to the frame with specially developed spring-loaded tips. This ensures that the fabric remains flexible enough to disperse wind pressure and always returns to a taught and water tight canopy.
The frame tips terminate into triangular rubber pockets, borrowing a nautical technique used to spread wind load and prevent tearing in sails.

The extra wide, softly angled form offers the additional advantage of safeguarding the eyes of nearby people.

Key Sustainability Design Features and Benefits

Even mild winds cause regular umbrella canopies to invert, resulting in permanently dysfunctional or broken umbrellas. 100s of millions of umbrellas are annually sent to landfill, threatening our environment and consuming resources

VortexVent defends itself by combining a two-ply canopy that disperses wind forces with a frame reinforced by Anti-Inversion-Struts. The frame and canopy are connected by spring loaded and triangulated tips, bringing extraordinary integral strength and resistance to tearing.

Together, these innovations challenge the perception of umbrellas as a throwaway item, setting a greater expectation for product lifecycles and pushing the market towards a new standard in sustainable umbrellas
