At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
What the road.cc scores meanGood scores are more common than bad, because fortunately good products are more common than bad.

The Brynje Super Thermo C-Shirt is a mesh base layer that shifts moisture away from your body well while adding just a touch of insulation.
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.
Verdict
Lightweight polypropylene base layer that shifts moisture well and dries out very fast.

Make and model: Brynje Super Thermo C-shirt
Size tested: M
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Brynje say, "A favourite among cyclist and summer hikers. Lightweight, super efficient moisture transport capability, insulates and dries better than anything. To maximise capabilities, use in conjunction with another top with a zip to vent, such as a cycling top or another Brynje product.
Use: All sports from cycling, skiing to fishing, but truly excels in high intensity activities."
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.
Rate the product for durability:
7/10
Rate the product for comfort, if applicable:
8/10
Rate the product for value:

Tell us what you particularly liked about the product
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.
Did you enjoy using the product? Yes.
Would you consider buying the product? Yes.
Would you recommend the product to a friend? Yes.
