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."
Dave Parker our CEO at PAST Outdoors, on one of his quarterly trekking trips in the New Zealand Alps wearing his favorite trekking trousers the Fjallraven Keb Hiking Pants.
Tips for choosing the right trekking trousers
Fit first: Test movement—squat, climb, stretch.
Fabric matters: Choose durable, breathable fabrics for longevity.
Weather readiness: Ventilated trousers for summer, waxed or insulated for colder conditions.
Pockets & extras: Evaluate storage for essentials.
Maintenance: Learn how to maintain performance with our waxing guide

Having visited Past Outdoors for the first time, I was attended to by Dave the CEO. I provided Dave with what I required and why, regarding a reliable backpack. Dave actively listened and gave, in clear concise, logical and competent - knowledge, skills and experience - feedback what he thought would best suit my backpack needs. That resulted in my purchase of the well thought-out and constructed Exped Lightening 50L Backpack. The surprising bit for me was how well it could be adjusted to suit my body size and weight of contends carried. Another aspect was that a pack of this size can always be collapsed down prior to closing and carrying - that is, a larger backpack can be adjusted down to suit circumstances, in contrast to a smaller pack cannot be expanded out to carry more. The way the shoulder, spinal and pelvic/hip adjustments work together are easy and stay put. The top section rolls and folds to firmly and securely close down, to provide protection from the elements and any loss. The system of ties further enhance the packs ease of carrying and functional stability. The pack is light in weight and certainly does not feel burdensome when carried. It’s a fit for purpose and functional bit ok backpack kit. Cheers.
Very happy with my Grayl Geopress purchase. Bought this product in store and Dave was super helpful in recommending this product to me! Thanks Past Outdoors, an overall wonderful experience.
