I have this jacket/pants as I commute 500kms a week for work. Whilst I really do love it, there are two spots on the legs that aren’t waterproof (where the zips are) and the inner jacket has a strange double sleeve design. Almost looks as if it should be for thumb loops but there isn’t any. Otherwise, a really awesome jacket!
Gore-Tex is just a brand name, all marketing. Any similar material should meet the same standards and provide virtually the same functionality. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GGEzJJYiROk.html
Probably, but still then, what makes it more expensive than my Klim Carlsbad which already has a back protector included, is laminated Gore-Tex (which already inflates the price), and overall has probably been built with better materials.
