Quechua Speed Hiking Trousers MH500 Review

Overview

The MH500 is Decathlon’s mid-tier hiking trouser: a slim, stretchy synthetic pant designed at Quechua’s Passy test centre at the foot of Mont Blanc and priced at about £30 in the UK. It suits day hikers and long-distance walkers who want a technical fit without paying Arc’teryx money. The trade-off is that this is a fabric built for comfort and speed, not for hard scrambling or dragging through grit.

Performance

Mobility. The headline is the stretch. Fabric that gives in two directions, plus preformed knees and a crotch gusset, means high steps and scrambles up a muddy bank don’t bind at the thigh. A forum user who bought the trousers for cragging found them light, stretchy and comfortable under both a harness and a rucksack, a combination that tends to expose seams and waistbands quickly.

Weight and feel. At 300 g in size L, the MH500 is light for a four-pocket trouser with a belt, though it isn’t in ultralight-pant territory. Owners describe the fabric as thin, similar to parachute material. That keeps pack-and-wear weight down and helps the trousers dry fast after sweat or a shower. Quechua says the synthetic fabric dries quickly and wicks perspiration to the outside surface.

Breathability. Quechua rates the trousers 3/5 for breathability and applies the same score across its hiking trouser range. That is a middling number, and it matches the intended use: temperate mountain walking, not a humid summer slog. Hikers heading into real heat will find shorts, or a lighter fabric with more open weave, cooler.

Durability. This is where the price shows. The same cragging user called them a near-perfect trouser but noted they won’t match denim or thick cotton if they’re being worn against grit. Thin synthetics also tend to snag on brush and rock. Against that, one long-time owner reports a first pair bought in Chamonix in 2019, then a second pair worn for the full 35 days of the Camino Francés in 2024, and rated them reliable over hundreds of kilometres of mixed temperatures and terrain. On sustained trail walking the fabric holds up; on abrasive scrambling it is the first thing to wear.

Fit and adjustability. Quechua describes a slim cut with a silicone-treated elastic waistband, and the trousers are listed as true to size. The built-in belt gives a secure waist when carrying a loaded pack, and the adjustable hems let the cuffs cinch against mud, ticks or a chain ring. The belt and cuffs are removable, which suits walkers who prefer a cleaner silhouette. Tall or long-legged hikers should check the inseam: sizes run L33 to L34 in the current UK range, and the sizing is French-based, so convert from your usual waist size before ordering.

Pockets. Two zipped hand pockets and two zipped thigh pockets are enough for a phone, snacks and a map without a hipbelt pocket. Zips mean nothing falls out during a scramble, though the thigh pockets will sit against a hipbelt on a loaded pack.

Weather. These are not rain trousers. Some retailer listings tag them as waterproof, but Quechua markets them for breathability and quick drying, and the thin synthetic should be treated as a wind- and shower-tolerant layer at best.

Pros & Cons

Pros

• About £30 for a technical, stretchy hiking trouser
• 300 g in size L, with fast-drying synthetic fabric
• Four zip pockets, including two on the thigh
• Preformed knees and gusset suit high steps and scrambling
• Adjustable hems and removable belt for fit control
• Long-term owners report multi-week use over hundreds of kilometres

Cons

• Thin fabric that won’t match heavier materials against grit and rock
• Breathability rating of just 3/5 limits hot-weather appeal
• Slim cut won’t suit everyone; French sizing takes conversion
• Not a rain trouser, and the built-in belt adds bulk compared with minimalist pants

Who Should Buy This

Hikers who want a dependable trail trouser for temperate-weather day hikes, hut-to-hut trips and long walking routes such as the Camino, and who care more about value than brand. Its price also makes it a sensible second pair for a thru-hike where wear is a certainty. Hikers who plan on off-trail bushwhacking, rough rock scrambling or hot, humid conditions should look at a tougher woven pant or a pair of shorts. Gram-counting thru-hikers will find lighter options if they’re willing to give up pockets, the belt and the gusset.

Verdict

The MH500 delivers comfort, mobility and sensible features at a price that undercuts most of the competition by a wide margin. It isn’t a rugged pant and it isn’t an ultralight one, but for trail walking in moderate temperatures it is one of the better buys in the category.
