Quechua Men's Hiking Trousers MH500 Review

Overview

The MH500 is Decathlon’s mid-tier hiking trouser. It’s a 300 g, bi-stretch synthetic pant with preformed knees, a gusseted crotch and four zip pockets, and it sells for well under what the name-brand equivalents cost. The trade-off is refinement. The fabric is a three-season workhorse rather than a hot-weather ventilator, and the slim cut punishes anyone who buys their usual size without trying them on.

Performance

Comfort and movement. Stretch is the headline. With 15% elastane in the weave and a gusseted crotch, the MH500 moves with a high step or a scramble without the seat or knees pulling. Buyers on Decathlon’s UK site rate freedom of movement at 5/5 almost across the board, and several describe them as comfortable enough to wear on a long-haul flight. One reviewer reports using them for camping, walking and cycling, with fast drying even after rain.

Fit. The cut is slim, closer to a skinny fit than the straight leg of most trekking pants. Owners with strong thighs or a preference for looser trousers are advised to size up. The stretch fabric forgives a snug fit, but there is little room for long underwear beneath. One UK buyer solves this by wearing leggings under them in colder months.

Breathability and weather range. The 3/5 breathability rating is honest. The fabric handles spring, summer and fall hiking, but it isn’t the airy, thin weave of a dedicated hot-weather pant. It also isn’t built for cold, snow or strong wind. Long-term owners treat the MH500 as a base layer in those conditions, paired with thermal underwear and an outer shell. Anyone who needs rain protection will still carry overtrousers.

Durability. This is where the MH500 earns its reputation. One long-term owner reports that a pair bought in 2019 is still in service, with no fraying, solid elasticity and intact stitching. A second pair from 2024 had logged more than 1,500 km, including 35 days on the Camino de Santiago, with only slight fading. That owner’s 2019 pair predates the current line, so the new version’s durability is less proven, but the fabric’s track record is encouraging.

Details that can trip it up. Waist hardware is the one recurring complaint. One Decathlon buyer reported the waist clasps breaking after the first wear, though the store replaced the pair without fuss. Washing is limited to 30 °C, which is fine for a hiker rinsing trousers on the trail but a small inconvenience at home. The four zip pockets keep a phone and small items secure when scrambling, a feature owners single out as practical.

Value. Active-Traveller’s walking-trouser roundup scored the MH500 6/10. It called the price astounding and said the pants are good enough for unfussy seasoned hikers, though less refined than pricier options. Buyers on Decathlon’s site score value for money at 5/5 in nearly every review, and some bought a second pair after the first.

Pros & Cons

Pros

• 300 g, with generous stretch and a gusseted crotch
• Dries quickly, according to owners who have worn them in rain
• Durable fabric; long-term owners report years of use
• Four zip pockets
• Very low price for a technical hiking pant

Cons

• Slim cut; many wearers need to size up
• 3/5 breathability, so it runs warm in serious heat
• Not suited to cold, snow or strong wind without layering
• Waist clasp failure reported by at least one buyer
• 30 °C wash limit

Who Should Buy This

Day hikers, section hikers and Camino-style walkers who want one durable, stretchy trouser for spring through fall, and who prefer to spend their budget on a pack or shelter. It also suits travelers who want a pant that survives a flight, a hike and a laundry sink. Hot-climate thru-hikers who want maximum airflow, and anyone with a larger build who dislikes a trim leg, should look at looser, more ventilated pants. Winter and exposed alpine use calls for a heavier or wind-resistant pant.

Verdict

The MH500 is among the best-value hiking trousers on the market. It’s durable and mobile, and its main faults are a snug cut and middling ventilation. Buy it, try it on first, and size up if in doubt.
