Whether you’re tackling rugged Australian trails or enjoying weekend bushwalks, the right trekking trousers can make all the difference. For many of our customers, comfort, durability and function matter as much as style. Finding the perfect trekking trousers is about more than just style—it’s about comfort, durability, and functionality on every trail. The right pair can make steep climbs, long hikes, and unpredictable weather feel effortless, while poorly chosen trousers can slow you down and leave you uncomfortable. 

Watch: Our take on Trekking Pants 

In this guide, we break down some of the top trekking trousers available at PAST Outdoors, including the Fjallraven Keb, Vidda Pro, and Barents Pro for men, and the Keb Hiking Trousers and Adventure Light Pants for women. You’ll discover detailed comparisons of features, benefits, and ideal use cases, along with expert tips for choosing the right trousers for your trails. We’ll also share maintenance advice, styling tips, and links to helpful blogs so you can make an informed choice and get the most out of every hike.

Why choosing the right trekking pants matters

Trekking trousers aren’t just another piece of gear—they’re your shield against the elements, your comfort layer, and your functional companion on every hike. Key considerations include:

• Fit: Slim, relaxed, or articulated? Your movement should never be restricted.

• Fabric: Breathable, quick-drying, and resistant to abrasion. Natural fabrics like G-1000® and synthetic blends offer different advantages.

• Functionality: Pockets, ventilation zippers, reinforced knees, and adjustable hems make all the difference on long hikes.

"I never realised how much trousers could improve my hiking experience until I tried the Fjallraven Keb Hiking Trousers Men’s . They’re durable, flexible, and perfect for multi-day treks."

- Tom R. Melbourne
