We've teamed up with adventurer, round the world cyclist and BBC presenter Mark Beaumont as well as Blacks and The North Face to give away one of the awesome new North Face Thermoball all-weather jackets - worth £170.

Billed as a "revolution in insulation technology", the ultralight jacket uses a synthetic alternative to down that not only keeps you super warm, but packs down so small that the whole jacket folds away into its own pocket.

"It's a revolution in insulation technology"

The technology is "designed to mimic the properties and compressibility of down, but with the ability to outperform in the wet," making the Thermoball jacket the ultimate in versatile outerwear.

So what do you have to do to get your hands on this sweet piece of kit? Well that's easy - simply watch the video above and tell us: According to Mark Beaumont, what are the three most important properties for adventure kit?
