Made from a light, low volume GORE-TEX 2.5 layer fabric, the Mammut Juho and Jona Jackets will keep you totally dry if you're trekking in wet weather.

Low weight and simple design make these waterproof jackets perfect to wear over your other breathable layers in cold wet conditions, and are equally useful when worn over just a baselayer if you're somewhere warm and wet.

Juho and Jona can be packed down to a very small size, so are easy to pack and take anywhere in your kit - or in your pocket.

We have a Juho and Jona up for grabs in this easy competition - with a twist. If you win you have to send us a photo of yourself wearing your jacket on a UK hill.

Name a UK stockist of either the Mammut Juho and Jona jacket
