The Arc ones are a bit thinner and I have found the fabric to be plenty breathable. I've used the Arc ones for summer alpine (without leggings) no problems and didn't find them too hot. I would have found both the ME and Rab trousers too hot for most summer alpine. in my view they are the best all round.

I've had a pair of the ME's too. They've got slightly less stretch and are less breathable. However they are the most windproof of the three.
