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 Giro Wind Guard Scuba Base layer is a really versatile piece of kit that can not only be used as a sub-zero baselayer or a casual outer layer, but also as a nifty makeshift ninja costume.
I've been reviewing this since autumn, so it's been quite tricky given the huge temperature fluctuations, but what I've found is that the durability and versatility of the Wind Guard Scuba make it a real pleasure to use.
The first area to address with the top is the hood and chin guard, which give it its unique look. The idea behind this is simple: to provide protection in the freezing cold without needing to have a separate hat or scarf. You can also wear them as either just a chin guard or a hood – you're not forced to have them up all the time.
Although I can't judge how effective they are in freezing conditions, the warmth provided on some pretty cold days suggests they would perform well.
The material used throughout the rest of the top is interesting, with ridges running across the inside. The idea behind this is to create warm pockets between them to increase insulation. This works well – it is a very warm piece of kit; a little too warm to wear as a true baselayer on milder days, though as the mercury creeps closer to zero it will be very useful.
Handily, it doesn't act as a baselayer alone: with a second windproofing layer on the front, I frequently used it as a casual outer layer in milder conditions. It has a decent level of breathability, making it comfortable to wear in mild conditions without overheating. The only drawback of using it in this way is the lack of pockets on the rear, so a bag/seatpack is necessary for carrying items.
The cut of the Wind Guard Scuba is fairly tight, but not uncomfortable. It also has a lowered back panel, which is useful when using the top as an outer layer, to protect your lower back when riding.
With an rrp of £99.99, it's expensive for a baselayer, but more acceptable when you consider its versatility and performance.
Overall, I was very impressed with the Wind Guard Scuba. Despite its high price, it's worth considering for anyone doing a considerable amount of cold weather cycling. Or you want to look ninja-esque...
Warm, breathable, strongly performing baselayer, which also makes you look like a ninja

The fabric used makes me think it must have been complicated to machine effectively given its ridged nature, but strong stitching means the construction is excellent.
Works well in serious cycling conditions and for a more casual outer layer. The ridged material keeps you warm and the breathability keeps you dry – what else do you want from a baselayer?
Seems well made and unlikely to fall apart any time soon.
Breathability combined with warmth makes this a winner, and the material is also soft against the skin.
It is expensive, but for those looking for performance it is a fair price to pay.
Tell us how the product performed overall when used for its designed purpose
It performs well. I didn't experience it in sub-zero conditions but from the coldest temperatures I used it in, I am confident this would perform very well as the mercury plummets.
