I know there are conflicting views but having used laminated kit in warm climates, I wouldn’t do it again.
I rode to Beijing in a Badlands. It was great across Tibet in the snow and sleet. It was a total liability across the deserts of the ‘Stans and western China - and I suspect the Badlands is about as well vented as anything you can get.
Not only do you get hot and bothered in a laminated suit, it’s amazing how quickly a laminated suit gets very, very smelly.
Other than cold, wet climates, now I’m with the chap in the cap. Layers built around a vented/breathable outfit and a rain suit when necessary…
