Our umbrellas are tested to withstand gusts of up to 40 mph, and unlike cheaper versions are designed to turn inside out and recover. All come with an impressive two year guarantee as standard. Vented umbrellas allow for extra resistance, allowing wind to pass through them, reducing tugging in high wind. However, their 16 panel construction limits branding.
See below how we test our umbrellas for wind speed.
