Decathlon lists 354 g in size L in its features and 345 g in its spec table (no size named); the heavier, lower-scoring 354 g is banded, and both are in the 290-369 g band 3. The size M weight isn't published, so M may be lighter.

What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Breathability*
Estimate: only 2 reviews about breathability (fewer than the 3 we need, so never above 8) 7/10How dry they keep you from sweat on the move, uphill.
2 reviews on breathability, e.g. "Waterproof, durable but short of ventilation.".
On and off*
Estimate: only 2 reviews about on and off (fewer than the 3 we need, so never above 8) 7/10How easily they go on and off over boots.
2 reviews on on and off, e.g. "getting them on and off over a pair of boots easy enough (though it’s not so easy with big mountaineering boots)".
Durability*
Estimate: only 1 review about durability (fewer than the 3 we need, so never above 8) 8/10How well the fabric and waterproofing hold up over seasons of use.
1 review on durability, e.g. "they’re very durable – in fact they feel like a pair of Gore-tex Pro trousers".
In short
Good for
- Cheap, packable waterproof cover for mountain walks in heavy rain
- Quick on and off over boots: side zips rise above the knee
Strengths
- 15,000 mm waterproof rating and a 3-layer membrane (Decathlon)
- Zips rising above the knee, to put them on without taking boots off
- Folds into its own pocket; 354 g in size L
- Elasticated waist with a drawcord
- Decathlon 2-year warranty
Weaknesses
- Decathlon doesn't say how the seams are finished, so rain protection is an estimate, not a reviewed score
- Weight is for size L, and Decathlon gives 354 g in one place and 345 g in another
- Leg length isn't adjustable: no hems are possible with the side zips, and one buyer had them tailored
- Breathability is 10,000 g/m2/24h, lower than many dearer overtrousers
- No independent test of the men's version, so fit and durability aren't scored
