Fjällräven Vidda Pro Ventilated Pants – Built for the Long Haul

I bought the Vidda Pro Ventilated Pants after one too many soggy, snag-filled hikes in trousers that promised “durability” and delivered disappointment. I wanted something that could handle dense brush, rocky scrambles, and sudden downpours — and these have delivered in spades.
Build & Materials
These trousers are made from G-1000 Eco fabric — a blend of recycled polyester and organic cotton — and they feel like they could survive a barbed wire fence and come out smug. The reinforced knees and seat are confidence-inspiring, and the hip-to-knee ventilation zips are a game-changer when you’re slogging uphill with a pack.
They’re not stretchy, but the gusseted crotch and articulated knees give you enough mobility to scramble, squat, and clamber over stiles without feeling like you’re wrapped in cardboard.
Weather Resistance & Breathability
These aren’t waterproof, but they’re highly water-resistant — especially if you reapply Greenland Wax. I’ve worn them through hours of drizzle and wet bracken without soaking through. The vent zips help dump heat fast, which is a blessing on muggy days or when you’re working hard.
Fit & Features
I’m 5’10”, 75kg, and the EU 48 fits me well — regular fit with a mid-rise waist. The adjustable cuffs and boot hooks keep things tidy, and the pockets are brilliantly over-engineered:
- Two hand pockets
- Two thigh pockets (one with an internal mesh sleeve)
- A knife pocket
- A loop for an axe (because why not?)
Use & Durability
I’ve used these for multi-day hikes, bushcraft weekends, and even gravel rides when the weather looked grim. After months of abuse, they’ve held up beautifully — no tears, no blown seams, just a bit of character-building grime.
They’re not ultralight, but they’re not trying to be. These are workhorse trousers for people who value longevity and function over featherweight minimalism.
Pros
- Bombproof construction
- Excellent ventilation for a heavy-duty pant
- Pocket layout is genuinely useful
- Ethical materials and long-term repairability
Cons
- Pricey (but worth it if you use them hard)
- Not ideal for hot summer hikes
- No stretch — not for fast-and-light missions
Final Verdict If you’re after a pair of trousers that can handle bushwhacking, bivvying, and borderline abuse, the Vidda Pro Ventilateds are a top-tier choice. They’re not the lightest or the flashiest, but they’re built to last, and they’ll probably outlive your boots.
