Comfortable fit but suits milder conditions only, despite the name

The Craft Zero Extreme Short Sleeve Base Layer sounds like it's intended for wintry weather. It's not. For that you want Craft's meekly titled 'Warm' range. This vest is meant for 'fair to cold' conditions. After wearing it from winter to late spring, I reckon you can delete 'cold' from that description. This is a two-season top, at its best when the temperature climbs into double digits.

It's made of 100% polyester, with "a hollow fiber on the outside for insulation and moisture transport". It didn't get noticeably soggier than other base layers in use, though being polyester it does hold onto odours more than wool or wool blends.

Where it falls down is in terms of insulation. This is a lightweight base layer, weighing just 72g compared to the 120g of my short sleeve Crane Sport base layers from Aldi. On some rides, it felt like cold winds cut straight through the thinner material of the Craft top. Granted, I live in North Yorkshire where it is colder than down south. I've not got a lot of padding either, and not being a T-shirt-in-January kind of northerner, I wasn't really comfortable in this until May was properly underway, or unless I overdid the outer layer(s).

Unlike some lightweight base layers — I'm looking at you, merino wool — it didn't develop holes and tears. There's a good amount of stretch in the material and it's well stitched. The cut is athletic, the Medium size fitting me as close as the Small of some brands. It's not constricting to wear, however, and the flat seams and soft-faced material are comfortable against the skin. The fact that it's machine washable at 60 degrees means it's easier to live with, as you can just chuck it the machine. A hot wash keeps it smelling sweet too.

On the whole, it's a well made base layer that should suit late spring to early autumn conditions. A price of £30 is about par for the course. Yet for that money you can buy three or more base layers from Aldi (for example), and I have done. I wore all of them more than this Craft one during the test as they were more comfortable on cooler days. On the rare occasion it was too hot for a heavier-weight base layer, I didn't wear one at all. So the Craft Zero Extreme often languished in my bike gear drawer, alongside an abandoned string-vest type base layer.

I use the crew neck long sleeve version and it serves me right through winter. I guess it depends on the level of activity and what you pair it with. One of my wardrobe favourites.

A poor review - craft base layers are very good, and like tailwind I find that when paired with the right top will serve it's purpose well. I have a number of these - both short sleeve and long.

Comments like "it felt like cold winds cut straight through" are a bit silly, given that it is not marketed as windproof! If anybody wants a proper review of this product, I guess they will have to look elsewhere!

I have the Craft Cool Mesh Superlight baselayer and it's my secret weapon for cold weather. In fact it's so good I sometimes wear it to winter outdoor events at work under my suit!

I've noticed no build up of smell (wife tested!) and its a first choice for winter cycling, walking, or even going to the office.

I agree with the comments in that I am very happy with my Craft top.

I also have the windproof version and its excellent for cooler days.

Both are worn (separately) under a Castelli Gabba top and they an excellent combination both in warm or cool weather.

Baffled by this review.
I wear mine nearly every 3 season ride in the UK as it has a perfect warmth/breathability ratio for me with varying degrees of arm/leg warmer weights & combinations to suit the particular day. Admittedly when it's 20C+ I switch to Craft's sleeveless mesh base layer and hot weather jerseys. It's close fitting and comfortable, and has worn and washed well. I have other Craft base layers for winter and they're of the same high quality of manufacture and performance. All polyester kit has a tendency to smell but I've found that this can be avoided completely by 1. prompt on the day washing 2. the addition to the wash of a modest amount of of 'Vanish'.
What your review is really saying is that you don't really wear base layers...

ZERO Extreme will become every year uncomfortable.
Although it is not written in the review, this shirt is troubled by protruding from a long sleeve from jersey. Not find use.
Should buy a long-sleeved rather than short sleeves.  39

I clicked through to here from the home page because I was curious to see how this could only get 3 stars. Like seemingly everyone else bar the reviewer, I love my Zero Extreme base layers, long and short sleeve versions, with and without windproof panels on the front. I use them for a variety of sports and find them excellent in much cooler conditions than the review rates them for. From a cycling perspective, I particularly appreciate that they are cut much longer in the body than any other base layers I have, keeping my whole back warm when I'm bent over on the bike. The only downside is the prominent Craft logo right at the neck, which, as I don't wear a shirt and tie which would cover it, prevents me from wearing them every day under my regular clothes at my excessively air-conditioned office.

Very surprised by a 6/10 score.

This top plus a gabba sees me through most of the winter in the north east.

Surprised by the low rating to, the long sleeve version is my preferred winter base layer although I do always pair it with a windproof jacket so maybe that's the issue here. On warmer days with a bit of a chill I use the craft windproof base layer and then just string vest type base layers when it's 20c+

I'd back the reviewer up to a point. I use the long sleeved version under a windstopper and its toasty in <10C conditions. However, using the short sleeved version with a non-windstopper thermal jersey I have found myself chilly even 8-12C (no extra wind, only air movement from riding speed). I do find that both SS and LS wick well, but I have given up on using my SS for 10C conditions. I'm the same weight and height as the reviewer (give or take a cm or kg) so perhaps our body types feel windchill particularly badly.
