Some excellent products for outdoor wear have been lost to time, with not a lot of local innovation in the area of open-weave/mesh wearables.
Working at Paddy Pallin in Little Bourke Street in the early 1980s, I packed up a few PP TechTee mesh shirts — the ones with two press-stud buttons on a cross-over collar, and a light brushed TechFleece trim collar. These shirts were also available in long-sleeved versions for a short time, but it was the short-sleeves that proved their value in layering effectively and wicking away moisture. Take the top two layers off if you were hot and sweaty and the shirt dried extremely quickly. The 4 shirts I have lasted all the way until around 2001-2002 when time caught up with them, literally falling apart at the seams, the press studs coming adrift. I have not seen anything similar to these excellent shirts over the years. On the other hand, a PP long-sleeved Tech-SunShirt bought in 1985 is still going — fabric, collar, press-studs 'n all!!
Castelli's cycling-focused mesh wear base layers work very well (popular among roadies in Spring and Summer to show their tatts and muscles!!), but it is tight-fitting (everything!) and can be uncomfortable, made along European sizes. It is an expensive brand that requires care and attention to fitting. I think Netti here in Victoria have mesh base-layers; not sure really.
"Tip of the iceberg" ???
Ah, right. I think you will need more than a mesh base-layer to venture up there and down...
