Klättermusen Asynja £330

“Premium feel & ideal for showery days”

Swedish climbing specialist Klättermusen is another outdoor brand known for sustainability. The lightweight Asynja rain shell is made from 3-layer Cutan fabric, which is Bluesign-approved, fully PFC-free and made from 100% recycled nylon. As a PU-based membrane it is also windproof, waterproof and breathable – but softer and more comfy than most, and with some extra give too.

This well-made jacket has some details that give it a premium feel – including a soft microfibre cuff lining and anodised metal components on the main zipper and rear hood adjustment. The 2-way main zip has an outer stormflap. You also get two roomy zipped mesh-lined pockets, with stormflaps and placed to sit above a hipbelt.

Overall cut is great, with shaped cuffs and an extended drop tail. The hood has a stiffened peak, but it needs to be pulled in pretty tight via the rear drawcord to get a secure fit without affecting visibility. On the hill, it did its job well, being ideal for on-off showery days thanks to its lightweight build, good breathability and reliable waterproof performance.

IF WE’RE BEING FUSSY

The main stormflap tends to catch the wind, while the mesh pocket linings can get snagged in the zips. The cuffs have unusual shockcord closures rather than Velcro tabs. And we reckon it might need regular reproofing if used heavily, as the DWR seemed to wear out quickly.

Verdict

A well-built, eco-friendly shell that was among the lightest, most packable and comfy jackets on test. It’s only let down by a few eccentric design features.
