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.
Good scores are more common than bad, because fortunately good products are more common than bad.
The Giant Rev Comp is a very good entry-level helmet offering a comfortable fit, decent ventilation and plenty of adjustment for a very reasonable price.
Some people just want a basic helmet that does the job while meeting the relevant safety standards – a simple click and go type of lid – and that is exactly what the Rev Comp is. There are no gimmicks or space age technology, just a polycarbonate cover bonded to an EPS (expanded polystyrene) shell.
Its design, though, has been pretty thorough when it comes to the vent position, often one of the failing points of many helmets below the 60 quid mark. You get 16 of them dotted all around, and I was surprised with how well they work – especially when you think that most pro-level helmets use well over 20.
Whether travelling at speed or hauling up a steep climb, I could still feel a cool breeze blowing through the helmet. The big plus part of this was that I never became massively hot, which kept down the levels of sweat running into my eyes as the pads don't get overwhelmed.
Those pads are not massively thick but they are comfortable against the skin. They are made from TransTextura Plus fabric which has anti-microbial properties to stop bacteria growth and associated smells from sweat.
Adjustment of the cradle is basic and simple, by way of a thumb wheel design that you can tweak on-the-fly to get the fit right. The Rev Comp comes in two sizes with a fair amount of overlap: small/medium (49-57cm) and medium/large (53-61cm).
Making it commuter friendly, you can remove that rear Giant-branded cover to expose the magnetic mount for Giant's Numen+ Link TL light (£24.99, sold separately), which is nicely positioned for getting you noticed amongst the urban traffic.
The Rev Comp feels decent quality, but with a lot of helmets now running their polycarbonate shell right under the lip of the bottom of the helmet, the Rev looks a little cheap with so much of the EPS exposed – especially on the white or yellow models. It can get damaged easily as well, when dropped or in storage.
It is just £49.99, though, which is a good price for this type of helmet. At 275g it weighs virtually the same as the Lem Volata and costs a tenner less. Ventilation is better too.
There are plenty of options out there, though, like the very good Specialized Align, which performed well with only its weight being a slight issue at 338g. It is only £30, mind.
On the whole, the Giant Rev Comp is a very good helmet for the money, covering all of the bases with ease.

AirFlow 16-vent cooling system is enhanced by three large center vents pull air through the helmet and over the rider's head to keep them cool
In-mold Polycarbonate (PC) shell with lightweight EPS foam provides maximum protection without compromising comfort
Lightweight, comfortable LiteForm™ webbing wraps around the head for a secure and comfortable fit. It's also hydrophobic so it won't absorb sweat or stretch out
Locking cam buckles keep the LiteForm™ webbing anchored securely
TransTextura Plus™ anti-microbial padding helps fight bacteria growth by pulling sweat from a rider's head and transferring it through the AirFlow vents. The natural property of the fabric inhibits microbes that cause odors
Cinch Pro™ fit system offers optimal coverage by cradling the occipital bone for full protection, support and comfort
Numen+ Link TL magnetic mount integration
Really good for the price.
All good so far, but exposed eps could be susceptible to damage.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
