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.

Craft's Women's Active Extreme X Round Neck Long Sleeve Baselayer is an outstanding bit of kit that keeps you warm and dry in cold to mild weather. The fabrics and fit make it exceptionally comfortable. For £45, you get a quality piece of kit made from a good percentage of recycled fabrics. It's genuinely difficult to pick fault here.

I still use several Craft baselayers that I bought while racing, over 12 years ago. The fabric has lost its sheen but they perform as they did on day one and, more importantly, there are zero signs of deterioration. I hasten to add that they are all black – white never fares so well. The Active Extreme X has certainly impressed during the test period; only time will tell if the innovative, recycled fabrics are as durable as Craft's former polyesters.

Fit and comfort

I followed Craft's sizing guide to test a small, and would say stay true to size. The fit is intended to be snug. There is ample length in both the sleeves and the body, with no riding up when you tuck the vest into tights or shorts, so the lower back stays well protected. There's a chance that some women may find the sleeve and/or body length too generous – I have pretty long limbs and would always rather have too much length than too little, so it was all to my liking.

While the vest really hugs the figure, the fabric is silky smooth with loads of give; it moves with the body well while riding and will accommodate all body shapes. It's so soft and supple that you are not even really aware that you are wearing it.

There is a subtle but effective female cut in the panelling. Yes, there are seams here, but they are all flatlock and you really don't sense any of them.

The neckline is just the height you want in cool conditions: not stiflingly high, but enough to protect you should you lower a jersey zip.


I've used the vest in a variety of conditions, with temperatures as low as 3°C and as high as 12. It's certainly proved versatile – Craft gives it a range of -5ºC to +10ºC.

In single-figure temperatures I've combined it with winter jerseys and gilets or jackets, and have been toasty warm with zero moisture build-up – the baselayer has been consistently bone dry at the end of rides.

Even putting in efforts of a decent duration, I never felt like I was overheating. The strategically placed, underarm mesh panels are really effective. Although I haven't taken it below 3°C, I have no reason to believe that it wouldn't perform well: its thin, snug nature means it can easily be used under a second baselayer too.

I've had good use out of it in milder temperatures, too. It doesn't become overbearing like some more substantial long-sleeved baselayers, such as Assos' Ultraz Skin Layer for example, and its snug fit means it sits well under tight, race-orientated jerseys.

Even if I was sweating due to exertion or conditions, the baselayer simply never clung on to any moisture; it's consistently wicking and drying in an instant.

Overall, it's a baselayer what will span at least three of our four seasons. Given our unpredictable summers, I'd say it could even make an appearance in a fourth too.

The Extreme X doesn't cling to odours as much as some polyester baselayers I've used, either; I've tended to get a few wears out of it before throwing it in the laundry. It comes out virtually dry from the machine, too.

All of this performance is coming from a good percentage of recycled, eco-friendly fabrics. The 39% Coolmax content is doing a lot of the quick-drying work, supported by 40% Seaqual, a polyester made from recycled, marine plastics. Craft claims that the remaining polyester is also recycled. The three fabrics combine to give a ribbed, waffle-like knit.

It's great that manufacturers are incorporating so much recycled material. As consumers, it gives us a choice, and with a choice we can make a difference.


Its rrp of £45 is a very fair price compared to others on the market. For instance, Megmeister's Drynamo Base Layer is £64.95, and Sportful's latest offering has a similar design to Craft's but will set you back £55.

There are cheaper options out there – both Decathlon and dhb have options for £30, though I can't comment on quality, fit or performance.


The Active Extreme X is genuinely difficult to fault; it ticks all the performance boxes – breathability, wicking, ventilation, warmth – and on top of that, the fit is functional and comfortable. With 61% recycled fabrics, it's a step towards a circular economy and, in my opinion, one with zero compromise in performance. It's £45 very well spent, not only as investment in a quality, three-season piece of kit, but also as a statement of support for a company trying to address environmental issues.

Rate the product for quality of construction:

Well-made with secure seams and quality fabrics. I still use Craft baselayers that I bought while racing, 12 years ago. There are no obvious weaknesses to be seen.

Rate the product for performance:

Great – breathable, warm and effective moisture transfer, with added underarm ventilation panels.

Rate the product for durability:

See my comments on construction. No reason to believe that this should be any different; it's looking like new after the intense test period.

Rate the product for fit:

No issues with it falling short in length – sleeve or body – plenty of give to accommodate all body shapes. If your arms are on the short side, you may find the sleeve a little long.

Rate the product for sizing:

I'd stay true to size, using Craft's size chart.

Rate the product for weight:

Negligible weight.

Rate the product for comfort:

Both fit and faultless performance make for exceptional comfort.

Rate the product for value:

My experience of Craft undergear is that it works well and it's made to last. You can get cheaper, but whether it will still be performing in years to come is not a given.

How easy is the product to care for? How did it respond to being washed?

Simple: 30 degrees with the rest of your kit. It's looking good still following these instructions.

Tell us how the product performed overall when used for its designed purpose

Performance, comfort and eco-credentials.

How does the price compare to that of similar products in the market, including ones recently tested on

Very reasonably priced for the performance. Both Megmeister and Assos offer female-specific baselayers that cost considerably more. There are cheaper options from the likes of dhb and Decathlon, but I can't say whether they're as good or will last as long.

Did you enjoy using the product? Yes

What's keeping it off a 10? I guess the sleeve length might not be to everyone's liking; fit always has an element of personal preference to it. On every other aspect, this is an outstanding bit of kit.

Emma’s first encounters with a road bike were in between swimming and running. Soon after competing for GB in the World Age Group Triathlon Championships in Edmonton in 2001 she saw the light and decided to focus on cycling. 

After a couple of half decent UK road seasons racing for Leisure Lakes, she went out to Belgium to sample the racing there and spent two years with Lotto-Belisol Ladies team, racing alongside the likes of Sara Carrigan, Grace Verbeke, Rochelle Gilmore and Lizzie Deignan. Emma moved from Lotto-Belisol to Dutch team Redsun, then a new Belgian team of primarily developing riders, where there was less pressure, an opportunity to share her experience and help build a whole new team; a nice way to spend her final years of professional racing. 

Since retiring Emma has returned to teaching. When not coercing kids to do maths, she is invariably out on two wheels. In addition to the daily commute, Emma still enjoys getting out on her road bike and having her legs ripped off on the local club rides and chain gangs. She has also developed an addiction to touring, with destinations including Iceland, Georgia and Albania, to mention just a few. There have also been rare sightings of Emma off-road on a mountain bike…
