Helly Hansen supplied an XL size Odin 9 Worlds 3.0 waterproof jacket rather than an L size, which turned out fortuitous as it means I can wear this over an insulated jacket without it feeling tight, something I’ve done a few times in bitterly cold winter weather. This means the jacket would be very baggy worn just over a base layer or thin shirt in summer but then this isn’t a jacket for that time of year. It’s very much a burly winter jacket in design and weight.
Chris Townsend’s verdictFor winter mountains this is a great jacket. It is quite heavy though and overkill for summer.

The fabric is fairly stiff and feels very protective in strong winds. The front pockets run virtually the whole length of the jacket, so the front is effectively double-layer. Breathability is okay but not as good as some – I think having a double-layer on the front is probably part of the reason for this. The emphasis is on keeping the weather out though, and the jacket does that well.
The hood is a big, helmet-compatible one but can be closed down around a hat or bare head without much difficulty. It gives excellent protection and moves with the head. There’s a RECCO reflector built into the big stiff peak.
How Chris tested the Helly Hansen Odin 9 Worlds 3.0
Chris tested this jacket on day walks and multi day trips in the Cairngorms in the autumn and winter of 2023/24. Conditions included heavy rain, soaking drizzle, blizzards, and ferocious winds. Weights were measured on Chris’s home digital scales.
The huge pockets will swallow a vast amount of gear. The bottom is cut off by a hipbelt but that doesn’t matter. Double zip pullers mean the pockets can be opened from either end or from the centre. There’s also a smaller chest pocket that’s great for a compass or smartphone, items that would disappear in the big pockets.
The underarm zips have double zip pullers too. They are quite stiff and a bit awkward to use. Wide cuffs fit over gloves and allow ventilation to the arms.
