The COMBO option is addressed to pilots who wish to make a more comprehensive technical inspection of the wing.

It covers both aspects of the paragliders' general assessment of the technical condition and the lines trimming and the examination of the fabric's porosity.

Only the combination of these two aspects, gives the pilot confidence in what condition Your paraglider actually is.

The number of hours spent in the air directly translates into the condition and length of the lines, time for trimming your wing!

Additionally, you want to be sure that the POROSITY of your wing will still ensure its safe use.
