It's made from Isolfil Merkalon polypropylene and the yarn is made up of loosely twisted smaller strands, so there's a large surface area to draw sweat away from your skin and shift it outwards, which it does very effectively. Although polypropylene moves moisture, it doesn't absorb it, so this base layer dries out really fast.
If you get a close fit – and that's not difficult because the Super Thermo C-Shirt is very stretchy – the mesh structure will trap a layer of air around your body for insulation. Being sleeveless, it doesn't provide masses of warmth, but I found it about right for cooler summer rides (or spring and autumn) when the temperature is in the high teens (°C). Brynje also have a Micro C-Shirt in a thinner weave that's suitable for warmer temperatures.
Start to overheat and opening the zip on your jersey gets rid of that insulating air immediately – quicker than with a solid-knit base layer – and dries off sweat faster.
All the seams are flat so you can't feel them in use, and although this isn't a cycle-specific cut I didn't have any problems with gaps around the lower back.
Also available in black and in T-shirt (£32), long sleeve (£39) and zipped (£49) options, and in various styles with wind-resistant panels.
Lightweight polypropylene base layer that shifts moisture well and dries out very fast.

Tell us some more about the technical aspects of the product?
Polypropylene doesn't absorb moisture, it just moves it, so this base layer doesn't get heavy with sweat and it dries super-quick.
Rate the product for quality of construction:
7/10
The construction is good, although there's not a great deal to get right or wrong here.
Rate the product for performance:
8/10
I really rate polypropylene as a base layer fabric because it doesn't absorb moisture. Occasionally, it can feel a bit scratchy, but not here.

The fabric works really well.
Tell us what you particularly disliked about the product
Not a lot. A string vest – sorry, 'a mesh base layer' – doesn't win any prizes for looking cool, but you can't argue with the performance.
