One of the most obvious places to start protecting yourself from the cold weather is a trusty set of base layers. In basic terms, these are tight-fitting, thermal undergarments that create an additional layer of warmth.

But the technology has moved on quite a way from woollen long johns (although these are still perfectly effective, too) and there’s everything from muscle-boosting compression wear to fabric that generates its own heat on the market these days.

You can also choose to go for a one-piece or two-piece option; the former being the warmest and the latter the more practical. And finally, if the conditions are making mincemeat of your clothing however many layers you add, maybe consider a heated mid layer or vest to turbocharge your efforts.

Ask which base layer you should wear at MCN Towers and a lot of voices will say Zerofit. One of those is Staff Writer Saffron Wilson who has been testing the Heatrub Move for 21 months and almost 2000 miles and is impressed by its comfort and quality.

She said: "If you’re after a baselayer that’s going to keep you warm but isn’t going to feel like a furnace underneath all your bike clobber, then the Heatrub Move Baselayer is a great solution.

"The quality is great, and the feel of the fabric particularly on the inside is lovely, but after a bit of use the fabric did stretch a touch. But there was no bobbling, and I never felt like I was overheating. Sure, the price tag is a bit more premium than some of the market, but it’s not at the top either, so you’ve got a nice mid-ranged price for a quality bit of kit."

Pros

  • Comfortable
  • Warm

Cons

  • Thicker than other base layers
A great fit, snug but not tight
Price: £14.99 (top) and £14.99 (pants)
The DXR Warmcore is available in men's or women's fit and is an economical option coming in at under £30 for both parts of the set.

Office manager Ali Silcox wore a pair for almost a year, 4000 miles and 12 washes and was impressed by the gender-specific fit and year-round practicality.

She said: “These lightweight thermals are great value and perfect for year-round rides. Hollow fibres increase insulation. They’re moisture-wicking and breathable too, making them perfect for winter or summer. 

“The zipped collar is comfy, too. Cut specifically for females, sizing is good and leg length ample. They are compression fit, so are snug but not tight. I’ve chucked them through the washer on numerous occasions and they’ve not lost their shape.”

Pros

  • Economical
  • Work year-round

  • Zip neck not for everyone
10,000 miles on test
Price: £85.49 (was £89.99) top
The Alpinestars Ride Tech may not be the cheapest out there (by some margin) but you can’t put a price on staying warm. MCN chief road tester Michael Neeves has worn his set for a massive 10,000 miles and vouches for their quality, giving them 5 stars.
 
He said: “These are much like two-piece summer base layers, but with double thickness in key areas and a high neck to keep out the chill.
 
“They’re made from comfy, moisture-wicking fabric and are a tight, compression fit designed to support muscles and not be bulky under leathers, but if you’re long in the body or Homer in the belly, it’s easy for the hem of the top to ride up.”

Pros

  • Moisture wicking
  • Long sleeves
  • High neck

Cons

  • Only for winter
Part of a system
Price: £24.99 (top) £19.99 (pants)
These base layers from British kit giant Oxford Products are part of Oxford’s Advanced layering system and designed to be worn next to the skin and below a mid-layer and outer garment to provide comfort all year round.

Deputy editor Emma Franklin put a set through their paces for 5000 miles and liked the comfort giving them 4 stars overall.

She said: "Made from a polyamide/polyester mix, it’s stretchy but isn’t a tight compression fit. There are also comfort-boosting details, such as flat-locked seams and printed-on care labels. This slightly more relaxed style boosts comfort under textiles but can result in bunching under tight-fitting leathers.

"When worn as part of a layering system the top definitely helps keep you warm, but I wouldn’t say it’s as toasty as a dedicated winter base layer, so you’ll need some sort of mid-layer over the top for chilly weather.

"During warmer weather, Oxford claim the fabric is wicking – and to a certain extent, it is as it carries moisture away from the surface of the skin. However, on particularly hot days when I was sweating a lot during sporty riding the Oxford Advanced gear did start to become a little overwhelmed and left my skin feeling damp, too."

The Rukka Outlast is a year-round base layer option designed to keep you warm in the cold and cool in the hot. Gareth Evans has worn his set for 3000 miles in all weathers and gives them 5 stars overall.

He said: "These Rukka Outlast base layers are remarkably effective. I’ve worn them in pretty much bookend conditions for UK riding – over 30-degree heat and below five-degree chill – and they’ve been seriously impressive.

"You’d expect that, given that the shirt and long johns add up to an RRP of two pence shy of £140 (although they’re heavily discounted at many shops now) and don’t be concerned when you open the packaging and they feel a little fragile, because actually they’re made incredibly well and have stood up to everything I’ve thrown at them.

"The science is the key feature here: they’re built using what Rukka call ‘phase change material’, which contains paraffin that can absorb body heat, and when conditions rise it turns from a solid state to a liquid. You can’t feel this happening, in my experience, but I’m in no doubt that it works. The technology also keeps you warm when it’s cold, with its solid state able to store and retain body heat. Clever stuff."

Things to consider before buying thermal base layers

The first thing a base layer or thermal has to do is fit underneath your kit. This isn’t generally a problem with winter kit, which tends to be looser fitting, but if you want to put thermals under your leathers, then you need to make sure they will fit.

Heated kit is a great option for deep winter riding, but you need to consider your use case. If you commute to an office within one charge from home and you can charge batteries at work, then that’s an option, but for longer rides or tours, wiring the kit in makes sense.

One disadvantage of heated kit is that if it stops working for any reason, you will be left exposed, so many riders prefer to layer up a non-heated kit instead. A base layer combined with a mid layer under decent winter kit should be enough for most riding conditions.
