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 1 review about breathability (fewer than the 3 we need, so never above 8) 8/10How dry it keeps you from sweat on the move, uphill.
1 review on breathability, e.g. "They keep air flowing through the jacket to maintain a dry and comfortable climate inside it".
Hood*
Estimate: only 1 review about hood (fewer than the 3 we need, so never above 8) 8/10How well the hood fits, adjusts and keeps rain off without blocking your view.
1 review on hood, e.g. "It has adjustment at the back and holds well in the wind while also moving nicely with your head.".
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. "this has a nice level of durability to it".
In short
Good for
- A light just-in-case shell for day hikes and trail mileage
- Walkers who want a jacket around 260 g that packs into its own pocket
- Warm to cool hikes where rain is showers rather than all-day downpours
Strengths
- 0.26 kg (Jack Wolfskin's figure), among the lightest waterproofs we cover
- 20,000 mm hydrostatic head and 15,000 g/m²/24h breathability (Jack Wolfskin's figures)
- Pit zips with water-resistant zips, adjustable cuffs and a fixed hood with one-point adjustment
- Packs into its own pocket as a small bundle that fits a rucksack pocket (OutdoorsMagic)
- Shell and lining made from recycled materials (Jack Wolfskin)
Weaknesses
- Jack Wolfskin doesn't say how the seams are finished, so rain protection is an estimate, not a reviewed score
- Weather protection and durability are estimates, not reviewed scores: only one hands-on test of this version found
- OutdoorsMagic calls it a casual-hike and just-in-case layer, not for top-of-the-mountain weather
- Hand pockets are hard to reach under a rucksack hipbelt (OutdoorsMagic)
