I bought this based on an mcn Reevsie review , I sold an RST summer jacket as it just didn’t vent I felt to hot in it all the time, this jacket though is perfect it lets in air around your arms and Front just enough to keep you nicely ventilated. It’s comfy well made even the neck area isn’t scratchy as some are, all the zips and velcros work well and are in the right place, it’s a really good jacket and I would highly recommend it
