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 mean

On those cooler days when the weather just can't make up its mind to rain or shine, you need a lightweight, packable waterproof jacket, and the Northwave Acqua Pro Rainshield is one of the best on offer. It comes at a price, though.
The Acqua Pro is part of Northwave's Rainshield Hi Plus range, which uses a membrane bonded to the fabric to keep the wind and rain out, well, to a degree anyway. Waterproofing is rated by how much water the fabric can deal with before it gets overwhelmed, and the Northwave can withstand up to 5,000mm in a hydrostatic head test. In the real world that means drizzle and light to average rainfall, the sort of conditions that the Acqua copes admirably in, helped by the fully taped seams. That membrane also keeps a chilly wind out.
Making something waterproof often has a negative effect on breathability, and this type of 100% polyester race cape often suffers quite badly. The Northwave can still get clammy, but it is definitely one of the better ones.
Around the 10°C mark, with a mesh baselayer and short-sleeved jersey on, I noticed the jacket starting to stick to my bare arms due to perspiration. That was at a reasonably brisk training pace, and while my jersey was also starting to get the same clammy feeling, it wasn't something I noticed while riding, only when I stopped.
Bearing in mind Northwave pitches this jacket for winter riding, I'd say it's acceptable because at, say, 3-5°C everything is fine, plus you can always undo the zip to let air flow in the front and out of the rear shoulder mesh vent. You soon learn how to regulate your body temperature.
The jacket's easy to get on and off while in the saddle, and folds down small enough to fit in a rear pocket so you don't have to keep it on for the entire ride.
It has a very race-orientated fit with a slender body that prevents any flapping in the wind and a very long dropped tail that's great for keeping road spray off your rear. A reasonably high neck stops draughts, and the arms are long enough when in a racing tuck to stop gaps between the elasticated cuffs and your gloves. (They have thumb loops too, if you want to hold them in place.)
You get a large pocket around the back and it's zipped for security. I wasn't really a fan of carrying too much in it, though, because the extra weight can make the jacket sag a bit and cause stuff to bounce around.
Colour-wise you have a couple of options: clear for that pro look, allowing your kit to show through, or the one we have here, part of Northwave's Be Visible range of fluoro gear. The material used means it isn't the brightest jacket out there, though.
Overall, the Northwave Acqua Pro is a great ambassador for the race cape genre, but you have to pay for that. At £99.99 it's one of the most expensive I've tested, and it's a little difficult to justify at full price, especially with the breathability being a slight issue.

Neat and tidy.
Keeps light rain out but not the most breathable.
A solid feeling zip and tough material.
5,000mm should resist 'light to average rain' and that is exactly what the Northwave does.
Around the 10°C mark things start to get a bit clammy but as Northwave aims this jacket at the winter months I'd say it's acceptable.
A slim race fit to stop any flapping, with a long dropped tail for protection from road spray.
The sizing in reality matches that of the sizing chart.
Weighs next to nothing and barely noticeable on your back or in a jersey pocket.
The material can feel odd against bare skin but that is the only issue.
At £99.99 it's at the higher end for this type of jacket. It goes a long way to justify it though, with its cut and quality.
How easy is the jacket to care for? How did it respond to being washed?
Northwave recommends a simple 30°C wash and natural dry. The odd mud stain was left over after washing if it had been a seriously wet ride.
Tell us how the jacket performed overall when used for its designed purpose
As a windproof and waterproof the Northwave does its job as you'd expect, and although breathability isn't brilliant it's one of the better options for this style of jacket.

The Northwave Acqua is a very good jacket compared with its rivals. I've worn this style of jacket from various brands over the past few years and this one is a little bit better than the rest all over. That high price stops it scoring a 9 for exceptional though.

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
