What do you wear under waterproof trousers?

It depends on what season it is. During the winter, it is best to dress according to the layer principle. By dressing in layers, you can easily adjust your attire when the weather changes. A wool base layer is warming and functions well even when it gets a little sweaty and damp. Synthetic layers are not quite as warm as wool, but transports moisture really well and are perfect during autumn and spring.

 What are waterproof trousers?

Waterproof trousers  are trousers with a high water column rating that helps them withstand all types of rain. But for extra comfort it’s not just about keeping the rain out, breathability is also important to help keep you dry even under strenuous activities. Good rain trousers therefore have a membrane that can withstand water from the outside while also having the ability to transport moisture and heat from the inside.

What is the difference between waterproof and water resistant? 

The difference between water resistant and waterproof rainwear is how much rain it can withstand before water begins to seep in through the fabric. This is due to its water column, which is a measure of how much water pressure the material can withstand. Clothing with a  water column rating of 10.000 mm withstands light rain and moderate snow. With a higher water column rating the garment can withstand persistent heavy rain and wet snow. When choosing rainwear keep in mind that if you are going to sit down or have a backpack on you, the water column needs to be higher so the added pressure on the garment does not allow water to penetrate.
