Dometic Grande Air Stay 390 S Awning 2026

Experience unmatched comfort and convenience on your touring adventures with the Dometic Grande Air Stay 390 S Awning 2026.

This premium inflatable static awning offers generous living space, modern design, and outstanding durability – all crafted to make your caravan setup feel like home.

Innovative Air Frame Design

Set up your awning faster and easier than ever.

The Single Point Inflation Air Frame system allows you to inflate the entire awning from just one valve, ensuring a smooth, effortless pitch every time.

Furthermore, multiple deflation points make packing down just as quick.

The Dual-Pitch™ Roof System not only boosts headroom inside but also channels rainwater efficiently, reducing pooling and wind resistance.

In addition, the Multi-Height System enables a perfect fit to a variety of caravan rail heights, giving you flexibility from site to site.

Spacious Living Area

The Grande Air Stay 390 S delivers exceptional interior depth, creating an open and airy environment that’s ideal for relaxing, dining, or entertaining.

Thanks to its 3.9 m width and extended 3 m depth, there’s ample room for furniture, storage, and family gatherings. Moreover, large front and side panels can be fully zipped out to open the awning veranda-style, while the panoramic windows flood the space with natural light.

Premium Materials for Year-Round Use

Built from Dometic’s Weathershield™ All-Season fabric, the Grande Air Stay 390 S is engineered for resilience across changing weather conditions.

This high-performance material is both UV-resistant and waterproof, making it perfect for long-term pitching or all-season touring.

Reinforced seams and heavy-duty zips add extra reliability, ensuring your awning stands strong through years of use.
