High-impact visibility for your business
Get noticed with heavy-duty, custom blockout flags that work harder for your brand. Unlike standard single-layer flags, these opaque outdoor flags use a special 3-layer construction with recycled PET fabric and a white light-blocking layer in between. This means your graphics stay crisp and vibrant even in harsh sunlight, with zero transparency from either side. Whether you're promoting a shopfront, setting up at a festival or standing out at a trade show, these weatherproof flags deliver professional 360-degree visibility that helps small businesses compete with bigger brands.
Built for outdoor performance
Choose from 3 popular shapes – feather, sail and teardrop – in 7 different sizes to fit your space. Each flag is made with wrinkle-resistant polyester that holds its shape when assembled correctly. You can bundle your flag with a pole or order just the fabric. Select from 4 base options to match your set-up: metal crossbar and water bag, plastic auger, metal ground spike or metal car tyre base. Add accessories like a square steel frame and water tank for extra stability. Our double-sided printing comes as standard, giving you rich, non-translucent colours that won't wash out in bright conditions.
Design, print and ship with confidence
Create your design using our online tools or upload your own artwork. We'll print your blockout flag with vivid, fade-resistant colours that look sharp from every angle. Your flag arrives ready to assemble with an included guide and video to help you set up wrinkle-free. With weather-tested materials and reliable shipping to your door, you'll have a high-quality outdoor flag that represents your business well for the long run.
Frequently asked questions
Blockout flags use a 3-layer construction with 2 layers of recycled PET fabric and a white light-blocking layer in between, creating 100% opacity with vivid, non-translucent colours on both sides. Standard flags use a single layer of recycled PET and are transparent when light shines through. This opaque construction prevents light washout for richer colour vibrancy and a more premium, professional look – making blockout flags ideal for corporate events, retail shopfronts and high-traffic areas.
Yes, you can have a different design on each side of your blockout flag. Because the opaque layer blocks light from passing through, both sides remain fully readable even in direct, harsh sunlight – making them highly effective for outdoor use where standard flags can appear washed out.
Yes to both. Our recycled PET textile is made from polyester, which is naturally resistant to wrinkles – following the assembly instructions correctly will help keep your flag looking its best. Our feather flags can also withstand wind speeds up to 40 mph, particularly when using the AirMesh material, which is specifically designed for windy conditions.
Yes, the material is DIN 4102 certified and classified as B1 fire retardant. Please be aware that washing your flag will cause it to lose this classification. If you do need to wash it, we recommend using cold water and leaving it to air dry.

You can choose from 4 base options at the point of ordering, with 2 heavy-duty options available at checkout:

The standard shipping package measures approximately 123 x 30 x 10 cm and weighs around 4 kg. Most bases ship together with your flag in one box.
