So what happens if you're climbing up a 100ft tree and your foot slips? In fact let's make it more interesting. Let's say the tree's hanging over the Amazon River and its rushing torrents are ready to flush you down some class 5 rapids. But then it gets worse. A tree limb rips through your cargos. As it skewers you like a kebab, leaving you suspended upside down, you think, "This is no minor wardrobe hiccup."

As you hang by the threads of some serious danger pants, you remember that you're Bear Grylls. You're the survival dynamo and host of Channel 4's Born Survivor. With a quick whip and snip of your pocket knife, you cut yourself free, swing onto a branch and survive. But barely. And as it turns out, bare-legged.

The partnership works because we both have similar goals. We're both obsessive in our desire not only to design and develop but also to ethically produce the most technically superior, high-performance gear in the world. So how does it all work? When the prototype gear is ready, Bear and his team go out and destroy the entire range. Or at least they try. Every drawcord, button and zip is tested and proved. And if a shirt or jacket doesn't pass the Bear test it gets overhauled until it works - when you need it, when it matters. We consider every possible weather condition. If the sun's scorching rays are causing problems, our SolarDry fabric and collars will protect you and keep you cool. If you're trekking through the jungle all day where you get completely soaked, just strip off and kick back. Your kit will all dry in a few nanoseconds. And last but not least, when the adrenaline rush is over and you're having that all important wind-down beer, let's not forget that the clothes also look pretty darn hot.
