CarbonX frame is a carbon-fibre reinforced fibreglass frame, which is suitable for both permanent and touring caravanning. Carbon Fibres are combined with glass fibres in varying amounts, according to pole diameters, to offer maximum strength. The frame is light and fully corrosion resistant. All CarbonX frames are supplied with the IsaFix locking mechanism. With IsaFix in place, keeping the frame in position is easy. With one press of the handgrip, a discreet 'click' tells you IsaFix is locked in position. CarbonX frame is made up of 6 layers:

Apart from these amazing features, Magnum Flint gives you many more perks. Both side panels and the front panel are removable and can be folded down. Both side panels have a mosquito mesh, to promote good indoor climate in your Magnum, without the annoyance of bugs. On top of that, there is top integrated ventilation in the front panel. 

The new Magnum Flint comes with extra long roof wings for additional strength. You can also purchase the optional storm securing set for the ultimate strength and protection of your awning by clicking here or in the 'Buy Together' tab above. In the options at the top of the page, you can also choose the additional veranda pole. This will allow you to zip out and fold down both side panels halfway down, providing your Magnum with maximum flexibility. Moreover, you can also choose one or two support poles in the options, to further secure your Magnum from side to centre leg pole. 

For plentiful vitamin D supply, the front window is extra wide, to illuminate the insides with natural light for your comfort. However, if you prefer darker surroundings, Magnum Flint comes with beautiful Collage Blue curtains as standard

The canvas are made of Isabella's well-known Isacryl 295g/m², their optimal, durable, breathable, fibre-dyed acrylic material. Isacryl has the highest achievable fade-resistance thanks to the pigmentation method. The density of the weave plus the impregnation all the way through prevents water ingress. Nevertheless, Isacryl is a breathable material, which facilitates the best possible indoor climate in the awning.

Isacryl is the most colourfast material you can have. This will allow the beautiful shades of your Magnum to stay vibrant and clean. This is important, as Isabella cared for the appearance of this awning; it is a part of their FLINT collection, i.e. a greyish colour scheme inspired by flint as a material in the following shades: The colours of Magnum Flint

The roof, on the other hand, is made of IsaRoof 285 g/m² - a UV acrylate coated polyester, with an added top coat in 2 layers. This perfect roof material will protect you from the sun, so you can find shelter in your Magnum Flint. Moreover, another special feature of this amazing awning is the full-length canopy, which will provide you with extra shelter outside the awning.

Magnum Flint also fits optional AnnexesNorthGrey or Sand 250. You can find them by clicking on the hyperlinks or in the 'Buy Together' tab above. The annexes are great for increasing your living area whenever you need it. They are also useful for storage, and can even be used as an extra sleeping space for unexpected guests! Moreover, you can separate your Magnum's space into two with a Partition Wall - this will improve the temperature homeostasis in both compartments (because temperatures fluctuate less in smaller rooms).
To create your own sheltered corner on those warm stuffy days, Isabella recommends their brand new awning accessory: Cosy Corner. It attaches to either side of Magnum very easily and will allow you to have your own 'me' space. If you'd rather chill in your awning in the summer, you will require maximum ventilation in your Magnum. That's why you are free to purchase a Net Side for either side panel of your Magnum (or two nets for both sides!). This brilliant awning accessory will replace the panel with a full mesh net, which will let the air to circulate freely through your awning without the annoyance of bugs. 
Last but certainly not least, Isabella's iconic Eclipse Sun Canopy comes in a size which is specific for Magnums 340 and 400. This spectacular sun canopy usually only fits full awnings, but Isabella made an exception for the Magnum. With this amazing accessory, you will be able to provide your Magnum (or your caravan with an adaptor!) with a 225cm deep sheltered space, where you can enjoy hot weathers comfortably. You can get it by clicking on the hyperlink, or in the 'Buy Together' tab above.
