Running in the winter can be a punishing business. Obviously there's the cold to contend with but because of working hours we also spend a lot of time pounding the streets in the dark. Most running brands stock a range of high-visibility gear to make night running as safe as possible. Ronhill's unique selling point is its lightweight vapourlite fabric, which promises to offer better breathability and protection from the sun than plain old polyester.

At £22.99 the t-shirt's aren't cheap but my advice would be to look out for offers on websites like wiggle.co.uk who are currently offering the long sleeve version (the one I own) for a snip at £14. I received mine as a gift so unfortunately I can't recommend any particular retailer but if I wanted another I'd definitely go to Wiggle. Anyone who owns running t-shirts by Nike or Karrimor will notice the subtle difference in the material. The vapourlite fabric feels slightly glossier and more comfortable to wear and while the weight difference is minimal it doesn't retain water like other running t-shirts. This means that if you get caught in a shower, it's a lot less of a problem and you won't feel like you're carrying around several kilograms of rainwater.

I can't fault the t-shirt on comfort, although I would say that Ronhill t-shirts run slightly larger than brands such as Asics and Nike. It's slightly looser on me than my other long sleeve t-shirts meaning that it's better as a top layer than as a base layer. Design-wise the t-shirt also scores highly- it has triangular detail on the front in black and charcoal grey with a silver hi-vis trim. The back of the t-shirt is features a 'black cat' motif formed by a large black square and two black triangles on a yellow background. It's very striking to look at, and you could say it's a clever touch for visibility as motorists will be able to tell whether you're coming or going.

All in all, the Ronhill Vizion t-shirt has helped me enjoy running in darkness like never before. I feel safer and dare I say it, more stylish. A clever addition to any winter running wardrobe in my opinion.
