What to Compare Before Buying
- Fit and size: This is size 18, so compare it with the fit you need and the clothing you plan to wear underneath.
- Weather protection: It is water-resistant rather than fully weatherproof, so check whether light rain protection is enough for your plans.
- Hood fit: The adjustable hood gives a more tailored fit, which matters if you want extra coverage around the head and face.
- Breathability: The stated 1,500g breathability rating is worth checking if you expect to wear the jacket while moving more actively.
Before You Decide
Confirm the size 18 fit, the Dark Grey colour and the water-resistant softshell construction before choosing. If you need a jacket for heavier or longer wet weather, compare it with a more protective alternative.
