I just wear what is practical for where I am going, with some concession to the means of transport. To me, motorcycling is primarily a way of getting around, not an occasion for showing off safety conscious, all the gear all the time togs.
Where I live now it is over 30ºC most days. I just exchange flip flops for a pair of sturdy sandals, and stick an open face helmet on my head. Around here, on an island that is 20 km wide and 50 km long, where traffic can be quite heavy, there is not much call for high speed. On any trip 70 km/hr is about as fast as I get, on occasion. 60 km/hr is a typical cruising speed, and a lot of the time is spent at less than that.
In more temperate climes, wearing heavier clothing is de rigueur. I normally wear boots outside, but do not have motorcycle boots. I throw on a leather jacket, leather mittens, and an open face helmet. Taking byways rather than highways, I still don't ride all that fast; typically reaching about 80 km/hr and seldom exceeding 100 km/hr.
I have never been able to get along with full face helmets. Besides, to me part of the joy of motorcycling is the smells and sensations that come with the wind in my face. Glasses are my eye protection; I only use a visor when it is raining or very cold.
The Nolan helmet I have at home has a visor that neatly pops up under the peak, where it is protected from scratching. Fortunately it fits me well, and is the quietest, most comfortable helmet I have used. It was a lucky find.
Off road I don't bother with a helmet, unless I am pushing it and doing crazy stuff
If I was into racing, or spending a lot of time at high speed on highways, I would learn to like full face helmets, and acquire more dedicated gear.
To me, the ATGATT mantra is fine sounding impractical nonsense.
