Castelli’s skullcap is warm and stretchy and it’s slimline enough to fit comfortably under your bike helmet.

Let’s be honest, skullcaps never look great. They’re like overshoes in that they’re ugly as sin but they do the job. File them under ‘necessary evil’. Castelli’s Viva Thermo Skully actually looks okay, though, in our humble opinion. Worn under a helmet, it’s acceptable, we’d say.

More to the point, the Viva keeps your head – including your ears – nice and warm. It’s made from a Thermoflex fabric – a polyester/elastane blend – with a brushed inner surface that provides a surprising amount of insulation. The different panels are flat-locked stitched together so you can’t feel the seams, and the raw cut edge means there’s no discomfort there when you wear a helmet over the top.

I used this loads in that arctic spell over Christmas and it made a huge difference to my warmth – not just to how warm my head felt, but to how warm I felt generally. You sometimes don’t realise just how much heat you’re losing through your head. I’d start to get cold on a ride and think about heading home – then sling the Viva on and decide to stay out a bit longer.

I’ve used many skullcaps before, including windproof ones that I’ve always found too sweaty. This one isn’t windproof but it is highly breathable and it really does make a big difference when the mercury is low. It's very comfy and takes up virtually no space if you stow it in a pocket just in case.

The Viva is also available as just a 10cm-wide headband (£14) if you just want to keep your ears toastie in milder weather.

Verdict

Warm and stretchy skullcap that fits under a helmet comfortably; does a straightforward job very well
