The Isabella Annex Sand 250 gives you a beautifully designed and highly practical way to expand your awning, whether you need extra sleeping space, a private relaxation area, or additional room for equipment and storage. Its warm Sand colourway brings a modern, neutral look that complements a huge range of Isabella awnings, while its clever zip-in side annexe system allows attachment on either the left or right side for maximum layout flexibility.
Built using IsaRoof 285 g/m²—a high-end, UV-resistant polyester with multiple acrylic coatings—this annex delivers long-lasting durability, weather resistance, and dependable breathability. The same premium material is used throughout the roof, base, sides, and tent walls, ensuring a consistent, high-quality finish designed to withstand season after season.
You can choose between two proven Isabella frame options: the Zinox steel frame with T-Rex locking clamps for rock-solid stability, or the lightweight CarbonX fibreglass frame with IsaFix clamps for easier handling and touring convenience. Both offer excellent support and secure pitching, allowing you to tailor the annex to your preference.
Measuring 250 cm wide by 145 cm deep, the Annex Sand 250 provides a generous footprint without overwhelming your pitch. It weighs approximately 14.40 kg with the CarbonX frame or 19.10 kg with the Zinox frame, while the fabric itself weighs just 9 kg, keeping transport simple. Compatible with a wide range of Isabella models—Prisma, Commodore, Ambassador, Capri North, Magnum 340/400, Ventura D250/D300, and Forum—it integrates seamlessly with your existing setup.
Additional comfort features include large windows for natural light, internal mudflaps for draught protection, and a built-in zip allowing the awning’s side panel to act as a partition wall. With the option to add an inner tent, it can easily become a cosy sleeping space.
👉 Select your ideal frame—CarbonX for lighter touring or Zinox for maximum stability—and enhance your awning with spacious, premium versatility.
