Same time I used a IXS HX 114 in front for four years and have been very happy with the part. But now I wanted to have a new motorcycle jet helmet with integrated sun visor. It just bugged too much to commit before the trip, whether the sun is shining or not. In my case the IXS HX 137 sits in the XL model perfectly, although I had doubts in the beginning. The lining has my head shape adapted very well. The integrated sun visor is a great relief, the lever damper can be operated, the tint I find very pleasant well while driving. Under the helmet we loudly about 90kmh, that must be clear to everyone Jethelmnutzer. A full-face helmet is quieter in any case, but does not look as good. After three months' use now I am very satisfied, the price performance ratio skin back definitely.
