Since ballooning began in Europe we have been restricted by cost to horizontal or vertical cut panels in our balloons. Now it has all changed with the introduction of a whole range of D type envelopes. D stands for DIAGONAL and this is exactly how the panels are cut. Now the choice of colour schemes for your new envelope has been expanded enormously.
D-type envelopes are hard to miss thanks to its unusual design. Panels are cut at 45°, creating the appearance that conventional balloons can achieve with difficulties and at great cost only. This cut has a long tradition in the USA, but gradually gaining its position in other destinations. Different orientation panels can then create variety of envelope designs - "spiral", "roof", "semi-spiral" and others - you can see more in the gallery.
D series envelope sizes are identical to Z series models up to the size of 4 000 cubic meters, have identical technical parameters, the same combinations with baskets and burners applies to them.
