If you’ve ever made the mistake of going for a hike wearing just jeans and a t-shirt you’ll know it can be a pretty sweaty, uncomfortable experience. But it doesn’t have to be that way! There are myriad products promising to keep you dry, warm and protected from whatever the weather can throw at you.

Listener Julie is keen to know more about that after she went on an adventure holiday without the right kit, leaving her cold and miserable.

She’s heard about fabrics that promise to ‘wick away’ the sweat and others that keep you warm in cold weather and cool when it’s hot. And what about the jackets that claim to stop rain getting in yet still be breathable enough to let vapour and sweat out. How does that work?!

I’ll be finding out by speaking to an expert in textile technology and the Gear Editor from the UK’s best-selling walking magazine.
