Our ratings (out of 10)

1 to 10, compared with the whole market. Each says what it's based on. How we score

Weight

From maker's figures 5/10

How much it adds to your pack. 5: Does the job. Average for wild-camping gear.

Decathlon lists 440 g in size L, in the 370-469 g band. The size M weight isn't published, so M will be a little lighter.

Rain protection

Estimate from maker's specs: hydrostatic head figure 8/10

How well the fabric and seams keep out heavy, long rain, when new. 8: Clearly better than most.

Estimate from maker's specs

Warmth

Estimate from maker's specs: thin shell (adds almost no warmth) 1/10

How much warmth the jacket itself adds. Most shells add little: wear a warm layer under them. 1: A real weak point.

Estimate from maker's specs

In short

Good for

  • Hillwalkers wanting a light 3-layer shell with big pit zips for heavy rain and hot, hard-working days

Strengths

  • Decathlon quotes a 3-layer 25,000 mm (Schmerber) membrane with sealed seams and waterproof zips
  • Weighs 440 g in size L, Decathlon's figure
  • 42 cm side openings; a buyer calls the pit zips massive and says he stayed dry in torrential rain and sleet
  • Six pockets: four outer zipped and two inner

Weaknesses

  • The 440 g weight is given for size L only
  • Fit runs snug: buyers say to try it over your thickest layers or size up (Decathlon reviews)
  • One buyer found the pockets small, the chest ones especially (Decathlon review)
  • Decathlon rates breathability at 15,000 g/m2/24h on the JIS test
