I agree with JMO. Nowhere near enough venting on any of Klim's gear AFAIC. Zipped openings aren't enough for really hot weather. Large mesh panels are heaps better, and the Revit (I think) with the roll down covering are pretty good compared to the completely removable panels. Although I think those still aren't large enough. Removable sleeves are brilliant and pretty common on Australian brands, which overall are pretty low quality unfortunately (apparently).
