Craft Active Extreme Crewneck baselayer



Excellent base layer for keeping you dry and comfortable on off-season rides

At 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.

The Craft Active Extreme Crewneck baselayer is an excellent option for keeping you dry and warm during off-season cycling.

In my opinion, Craft's off-season base layers are the best by far. If I have a big ride coming up at the weekend, I always make sure I have a Craft base washed and ready to go, and this one is the best of the lot for most conditions.

The Craft Active Extreme base layer is comfortable as soon as you put it on because it's thin and lightweight and there are no seams in the body. The seams around the shoulders and down the arms are flatlock stitched so you're barely aware of them.

The polyester fabric is ribbed and super stretchy so pretty much everyone will get the close fit that's vital for a base layer to work effectively. I'm tall and pretty skinny and I found the arms and body to be long enough to avoid exposed skin.

The best aspect of the base layer's performance is its ability to keep you feeling dry during a ride. Craft reckon this is down to the six-channel fibres they use against your skin and the hollow fibres on the outside that transport moisture to your next layer of clothing.

I couldn't vouch for the mechanisms involved but I can tell you that the base layer does a great job of shifting sweat away from your body.

It also helps provide a decent level of insulation although, to my mind, that's not such an important consideration because you can always adjust your outer layers to get the level of warmth you're after. I might swap to a warm merino base layer in really cold conditions – when the temperature is very close to freezing and I want all the warmth I can get – but I find the Active Extreme works brilliantly above that level.
