Gore Bike Wear Xenon Thermo Jersey



High-quality, breathable jersey for use from autumn right through to the end of spring

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.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Xenon Thermo Jersey isn’t the most hi-tech article in the Gore lineup but it’s a sound everyday jersey that you can wear as either a mid-layer or an outer layer, depending on conditions.

The Xenon is made of two different types of fabric. The white panels are brush-backed polyester while the red material, which is used for the most exposed areas, is a little denser to keep more cold air out. It’s in no way windproof, but it does give you a bit of extra warmth. Both fabrics are highly breathable and you can open the front zip, which goes down to navel level, if you want to increase ventilation.

The cut is slim so there’s no fluttering about even when you crank the speed right up, and the fabrics are hugely stretchy so you get unrestricted movement. The arms are long enough to keep your wrists well covered and the collar is high, especially right at the front, so you won’t get any draughts down your neck either.

As usual with Gore, everything is neatly designed. The fact that the zip is only three-quarter length, for example, means you don’t get that rolling wave effect when you lean forward to the bars. It’s slightly less bulky than normal. You also get a flap behind the zip to stop the wind whistling through, the puller locks in place and doesn’t rattle, and a chinguard up top prevents scratching – little features that all add to the overall quality.

There are three pockets in the lower back, the tops of the side ones slightly angled for easier access, and an elasticated hem takes up any slack around the bottom. There’s a generous helping of reflectives too, making you noticeable in headlights at night.

Worn on top of base layer, the Xenon provides enough insulation for most autumn and spring temperatures and it doesn’t get easily soaked with sweat when you turn up the intensity. Quite the opposite, it shifts moisture well and dries super-fast.

It’s just as useful in the winter, when the lack of bulk makes this an effective mid-layer worn underneath a windproof. We’ve been using it alongside Gore’s own Oxygen softshell jacket for sub-zero rides and stayed warm and comfortable.

Weaknesses? We’re doubting the wisdom of white panels down the centre of the back – just where your rear wheel sprays all the gunk from the road if you don’t use mudguards. Fine if you live in Spain or Italy or somewhere else dry, not so good for typical UK conditions. As well as orange/white and black/white options, Gore do this jersey in all black too, which might make more sense.

Other than that, we’d have to say that the price is a little expensive, even though you’ll get plenty of use out of this jersey across three seasons.
