🛏️ More Space. More Comfort.

The popular flat-back design has been carried over and refined, giving you maximum usable internal space without increasing the footprint.

🌧️ Built for Every Season

Constructed from our premium 20,000HH Aeroshell™ Fully Breathable Blackout Fabric, the Defier MK4 is designed to keep you comfortable whatever the weather.

The breathable material helps reduce condensation, while the blackout finish keeps the bivvy cooler in summer, darker at sunrise and warmer during colder months.

Whether you’re fishing through heavy rain, bright sunshine or frosty mornings, the Defier MK4 is built to perform.

💨 Improved Ventilation & Visibility

The MK4 introduces upgraded windows that can now be opened and closed from inside the bivvy using convenient two-way zips.

Combined with the rear ventilation system, this allows you to easily regulate airflow without stepping outside keeping you cooler on warm days while helping reduce condensation.

👀 Adapt Your Shelter in Seconds

The fully zipped front panel can be removed in moments, transforming the Defier MK4 into an open-front shelter.

The large peak and letterbox opening allow you to keep an eye on your swim while remaining protected from unexpected showers.
