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.
You know the old saying, 'cover your head, 40% of heat of lost through it' and while that may be a bit of a myth there's no denying that a layer under your helmet can really increase your cold weather comfort on the bike. Craft's Zero Extreme WS (Wind Stopper) Skull Hat is one option for doing just that.
The Zero Extreme range is a composite of their Pro Cool (material to cool you in warm conditions) and Pro Zero (material for cold conditions), with the idea being that the Pro Zero on the inside sits close to your skin keeping you warm, whilst the Pro Cool outer wicks the moisture away. A middle weighting (130g/m2 as opposed to 170g/m2 for the Pro Zero), the idea is that it is used when you are working hard enough to garner a sweat in cool weather, rather than extreme conditions as the name may suggest. It also presents a good thickness for under helmet wear - not too bulky as to leave your helmet teetering on top in only a gesture to safety.
A basic 'beanie' cut, it doesn't shape over the ears or down the neck but still covers both areas well. It is a comfortable fit which doesn't drop down to your eyebrow as some skull caps I have worn do, creating a nuisance while riding. Craft say it could be worn on its own but the styling is very much for performance rather than looks, with the Wind Stopper section looking a bit odd for casual attire.
The problem with skull caps is that you will often work up a sweat as your climbing - when your speed drops and you are working harder - leaving the cap wet. As you begin the decent, all that sweat evaporates away and you are left with a cold head. The Wind Stopper element here helps to prevent this, the panel is stitched over the front section of what would otherwise be a complete skull cap. This means the wet outer layer (due to the wicking doing its job) doesn't get a sudden onslaught of wind causing a quick and sudden temperature drop. It works well in practice and did a good job of keeping my head warm even once I'd sweated into it. The Wind Stopper layer obviously helps too when overall wind picks up, providing an extra defense against a chill. I found it warm down to around 6deg, below that I started doubling up with another buff or cap.
The cap retails for around £16 which I see as good value. It is a comfortable, well designed piece of head-wear - more so than most other headpieces. Having the added Wind Stopper layer is excellent at keeping the wind chill at bay and it hasn't inflated the price. If you find your head getting cold, or are struggling in the cold, you may want to consider this skull cap.

Not too tight as to feel unpleasant but didn't flap in the wind either. Wicking worked well in keeping my head dry.
