In the particularly hot months I have had to use small piece of cloth under the mask so I can remove it after my commute and not have a humid mask on my face, but that was the only issue I had. Even with the extra cloth I did not have trouble breathing (I specifically try to not exert too much effort when commuting on a bike because the sweat on my back would be a much worse source of discomfort than the mask)
