I took the risk of trying them in the summer heat, and the reviews blew me away!! But when I got them in my hands and put them on — it's simply amazing))) Super lightweight, cool to the touch... It seems transparent in the sun when you hold them, but once worn you feel lightness and comfort; the fit is perfect. You can wear them anywhere: office, street, walks around and outside the city. These are truly technological trousers. Thanks to the website for the promotional price and to Helikon for the quality. Height 171, weight 80, took size M and it fits perfectly. You can also insert soft pads in the knees, bimba.
