What we don’t like about the Odin 9 pants: Expensive; Only black colour available;
Lots of pop fasteners which can be fiddly.
Premium gear commands premium pricing. That phrase echoed around my brain when I first saw the £400 price-tag of Helly Hansen’s Odin 9 World’s Infinity Shell Pants. I typically test and review much cheaper, almost budget waterproof overtrousers, so trying out a top-of-the-range pair would be a very interesting test for me. Could they offer anything radically different for the extra expenditure?
As a keen hiker and backpacker, I rely on quality rainwear to keep me dry in the notorious variable UK weather. However, I’ve never seen waterproof trousers as being as important as a quality waterproof jacket. That viewpoint was set to change as soon as I unpacked the Odin 9s. Clearly, they are no ordinary pair of overtrousers.
Helly Hansen has cultivated a 140-year reputation for leveraging cutting-edge fabric technology and relentless innovation to create best-in-class gear for the most extreme environments. The Odin 9 Worlds Infinity represent the pinnacle of their expertise, loaded with a proprietary set of features designed for unmatched all-weather performance.
I needed to discover whether these waterproof pants could live up to their price point in real-world conditions. I put them through several months of testing in a range of weather scenarios on long-distance trails, icy mountaintops, slick muddy slopes and everything in between.

Sizes and Colours
The Helly Hansen overtrousers are offered in the full range of standard men’s and women’s sizes -specifically, the sizing options include Small, Medium, Large, Extra Large, and Double XL.
I ordered the large size and I’m a 6ft3 male. I would say they are on the snug to slim-fit in terms of sizing and you may wish to get a size higher than their sizing guide recommends. That being said, I’m fairly happy with my choice as I didn’t want too much excess material flapping around.
When it comes to colours, the overtrousers are currently only sold in ‘classic black’. To be honest, this isn’t a problem for me as they will go with any colour waterproof jacket and don’t show the dirt you inevitably pick up on muddy hikes.
The combination of expansive sizing up to XXL and timeless black color means finding the right Odin 9 Worlds overtrousers to meet your needs and preferences is straightforward. Just select your usual pant size and the weather-proof black pants will integrate seamlessly into your outdoor wardrobe.
Features of the Odin 9 Waterproof Overtrousers
The Odin 9 pants are loaded with innovative features and cutting-edge design details to deliver premium performance for mountain adventures. As Helly Hansen’s flagship overtrousers, they incorporate the brand’s most advanced technologies and materials to create a pair of waterproof pants ready to handle the most extreme environments.
Materials and Technical Fabric
The Odin 9 Worlds pants employ Helly Hansen’s Helly Tech Professional construction which is their proprietary 3-layer system engineered for uncompromising weather protection. It combines an exterior protective fabric, a breathable waterproof and windproof membrane in the middle layer, and a quick-drying moisture-wicking inner liner. This construction keeps the wearer completely dry on the outside while allowing interior condensation and sweat to escape.
The outer shell fabric is made from 100% polypropylene treated with a PFC-free DWR (durable water repellent) finish. This chemical-free coating causes water to bead up and run off the surface rather than absorbing into the pants. DWR contributes to the overtrousers’ full waterproof rating of 6/6. The polypropylene shell resists abrasions, tears and snags better than standard nylon or polyester while still offering full range of motion.
Inside, the pants integrate Helly Hansen’s proprietary LIFA Infinity Pro insulation. This polypropylene yarn-based fabric offers permanent heat retention and moisture wicking capabilities due to its advanced fiber structure and construction. It maintains insulating ability even when wet. LIFA Infinity Pro aids the Odin 9 Worlds pants in achieving their full 6/6 breathability rating and gives them excellent next-to-skin comfort.
Articulated Knees
The overtrousers’ articulated knees are pre-shaped to allow full freedom of movement when hiking, climbing or skiing. The gusseted crotch utilizes a diamond-shaped insert for increased stride length and to eliminate binding and restriction during active use. Very thoughtful engineering in the crotch – it’s certainly no fun hiking all day with pants that pinch and chafe!
Other Features
An adjustable velcro waistband and built-in boot hooks on the leg cuffs help achieve a dialed-in, secure fit. For accessible storage on the go, the pants include a zippered thigh pocket which is fully waterproof. The full side zippers up and down each leg make taking the overtrousers on and off over boots and layers a breeze. Bear in mind though that there are several pop fasteners inside the trouser leg which are used to keep the trouser tight to your actual leg – this can make getting a booted foot through the leg of the pants tricky until you undo the fasteners.
The Odin 9 Worlds pants also integrate RECCO® technology. These are reflective strips which can return a Recco signal and are built into the legs to facilitate emergency detection in case of an avalanche or other incident. This can greatly improve chances of a fast rescue and recovery.
Additional thoughtful design details include fully taped seams to eliminate leaks, YKK water-resistant zippers, and an embroidered Helly Hansen logo on the thigh which I very much like the look of. The combination of innovative fabrics, construction technology, and functional features enable the Odin 9 Worlds pants to offer elite technical performance with 6/6 ratings for waterproofness, windproofness, breathability and durability.
Weight
Helly Hansen specify the weight of the overtrousers as 550g, but on my scales I actually measured 500g for the large size – about 10% lighter! I’m guessing the XXL would be up at 550g. They pack down pretty small into a day rucksack and can be there when you need them in a jiffy.
In Use
Having extensively field tested the Odin 9 Worlds pants across a wide range of conditions and activities, I’m very impressed with their performance and comfort. The overtrousers have lived up to expectations as a premium pair of waterproofs.
A key component to my mind is the LIFA fabric technology. LIFA fibers are hydrophobic, meaning they actively repel water rather than absorbing it. This allows the overtrousers to achieve fully waterproof, breathable protection without relying on chemical coatings.
The pants provide everlasting water repellency that never needs reproofing or chemical treatment after use. This is a game changer, and definitely justifies the price tag in my opinion. Wearing them on a jetski, the pants kept me warm and dry as expected while handling the wind and splash. The fit and articulated knees allowed me to maneuver freely and the fabrics proved up to the task, keeping the elements out. For water sports and boating, the Odin 9 Worlds deliver.
I did find the sizing slightly ‘snug’ on my Large size (L) pants and may have preferred to size up, but this is something only you can decide. Personally, I appreciated the sleek fit and lack of excess material flapping in the wind, but buyers should consult the size chart to ensure proper fit.
For skiing and snowsports, I found the overtrousers excelled. The fully waterproof and seam-sealed construction kept me dry through repeated falls in snow on my skiing holiday in France. The side zips made taking them on and off over ski boots simple, and Velcro cuffs sealed out snow. The adjustable waist and built-in boot hooks kept them securely in place without impeding motion. They paired great with the matching Odin 9 Worlds jacket as a system.
Based on my testing, the breathable LIFA fabric prevented overheating during active skiing and hiking. I stayed warm but not clammy thanks to the moisture-wicking inner liner. Though designed for colder use, the pants ventilated well enough for me during moderate temperatures. I appreciated the climate-regulating abilities of the 3-layer construction.
In general, I found the overtrousers offered excellent quality befitting their premium price tag. They are thoughtfully designed for mountain sports, as evidenced by details like the RECCO reflectors and mini thigh pocket. The materials and construction live up to Helly Hansen’s reputation for high-end weatherproof gear.
Across all activities, the Odin 9 Worlds pants delivered reliable water and wind protection during heavy downpours and windstorms. They stood up well to abrasion when bushwacking through dense brush yet allowed full freedom of movement for scrambling up inclines. The polypropylene shell resisted tearing or damage from sharp branches.
For challenging hikes and long days outdoors, they provided welcome protection from the elements while remaining breathable on ascents. I also appreciated small touches like the easy-access side zips and adjustable leg openings for dialing in the fit over boots.
Based on extensive testing in the UK climate, I can endorse the Helly Hansen Odin 9 Worlds overtrousers for active outdoor pursuits in wet and cold conditions. They provide top-tier performance to match their premium quality and technical construction, making them a sound investment for frequent outdoor enthusiasts and professionals.
