I know people will be thinking “Yeah but they’re proper technical riding fabric”. But a pair of riding trousers has 3/4s the material and most of the complex shapes etc and costs a third as much.
(OTOH the Fort airflexes are rated 2000mvp which is barely breathable at all, POC claim 30000 which is massively breathable, about as good as it gets. TBF I don’t believe that number’s realistic, for a cordura reinforced garment- at best it’s got to be the lab rating of the most breathable fabric in the things, not anything like the real world result of the overall garment or taking into account the reinforced parts which will be much less good, but I think it’s still fair to say that they’ll be miles more breathable than the cheap alternatives people are looking at)
