Introduction

Waterproof trousers come in a huge range of styles. Each one best suited to different activities from lightweight race kit to hard-wearing and durable mountaineering pants designed to withstand long winter days.

This guide will help you recognise how different features make waterproof trousers more suitable for different activities and how they should fit.

Fabric

What fabric should I choose?

The fabric of the waterproof trousers is often a great indicator as to what kind of use the product is intended for.

Generally, super lightweight fabrics are often used for waterproof trousers designed for use in emergencies. These don't have a particularly durable face fabric, but can often be a kit requirement in adventure or ultra races. They must be able to offer a degree of protection should they be needed.

On the other side of the spectrum, heavyweight fabrics have a higher denier face fabric and offer more durability and protection from the elements. They're usually designed to be worn all day in wintry conditions.

The seams on all waterproof garments should be sealed. Also known as taped seams, these ensure that water doesn't work it's way through the stitch holes in the fabric.

For general hillwalking through late spring to early autumn you are likely to need them multiple times, so buying something that offers a good balance of durability and protection is ideal.

The level of performance and durability of waterproof pieces will vary greatly, our guide to waterproof fabrics offers more in-depth information.

Zips

Leg & ankle zips

Having a zip on the side of waterproof trousers can make it easier to get them on and off on the hill without having to take footwear off. These zips can vary from just a simple ankle zip, to almost full-length 2-way zips that can be opened from the top for ventilation when you need it. Although waterproof trousers are generally breathable, the body generates excess heat when working hard, so it is handy to have extra ventilation without sacrificing protection.

More technical waterproof trousers will often have a more robust section of fabric at the instep. This ensures better durability in such a high-wear area, while waterproof mountaineering trousers have an inner gaiter to prevent rain and snow from riding up inside the trouser leg.

Packable trousers

Some waterproof trousers will pack away into a small stuff sack, while others aren't designed to be packed down at all. If you only want them as a backup in case you get caught out with the weather then going for a packable pair is a good choice. When you are planning to wear them all day, you don't need to worry about whether they pack down or not because durability and outright protection take priority.
