The Trango X-Light 2 is based on the Trango XC2 and is manufactured in three certified sizes. The S is certified EN C, while the S/M and the M size are both certified EN D, and have substantially longer speedbar travel, resulting in an increased top speed of 5-7km/h compared to the XC2. This should come in handy for the X-Alps pilots, with their tendency towards evaluating flying conditions on a different scale compared to the rest of us(!) but it also makes the wing very interesting for someone looking for a solid, predictable wing in the EN D category that WON’T pack itself back into the bag at the first given opportunity, yet still has the performance to give the 2-liners a good battle to the goal line! As anyone who has flown the XC2 in a competition environment will testify, this wing has amazing performance and can keep up with the full-on comp wings except at the very top of the speed range – this should now be addressed!
