Helly Hansen Odin H2 Flow Jacket Review

HH Odin H2Flow Jacket

In this our second installment of Helly Hansen reviews, we’re in more familiar territory as we take a look at the Odin H2 Flow Jacket.  Could this be the King or Allfather of jackets as it’s name suggests, well lets find out.

Odin H2Flow Jacket








Born by the sea, raised by the mountains and trusted by professionals… both emotive and evocative, but is this self proclamation an apt description of the Helly Hansen brand?  A casual glance at the Odin H2Flow jacket and you can see where they’re coming from; the Odin H2flow jacket it screams quality, versatility and adaptability which uncannily are at the core of the Helly Hansen ethos.  So whether you’re climbing mountains today or skiing down them tomorrow, the design of the Odin H2Flow Jacket means anything is possible.

The Odin H2Flow jacket is classed as an “advanced shell jacket” but this really doesn’t tell the full story.  With their Patent Pending H2Flow technology at its core







the Odin jacket offers you a dash of light insulation in key strategic areas and utilises the H2flow mechanical venting system to keep you cool; equalising temperature within the shell when its needed.  Lets face it, most manufacturers can produce a waterproof shell, vapour management or breathability can be somewhat more elusive.  For a substantial jacket, Helly Hansen have done a superb job of eradicating the greenhouse effect, especially during a heavy downpour.

The Odin comes equipped with all the features you’d expect from a jacket of this type:

  • 2Ply laminate construction
  • Full stretch construction
  • H2Flow system with torso insulation
  • Water resistant YKK Aquaguard® center front zip
  • Hood des igned for helmet use
  • One hand hood adjustments
  • Welded YKK Aquaguard® zip hand- and chest pockets
  • H2FLow system
  • RECCO reflector
  • Aquaguard® pit zips
  • Zip-out softshell snowskirt
  • Adjustable cuffs
  • Bottom hem elastic adjustment
  • Harness and pack compatible design
  • DWR Treatment

For some, weighing in at 760grams might sound heavy, but when you consider it’s capabilities this is nothing and I can think of pure waterproof shells which tip the scales at virtually the same weight and more.  Versatility is the name of the game here and with no expenses spared this beastie can adapt to most situations with aplomb, which is fantastic if you ski, climb or hike throughout the year.

One feature that deserves a special mention is the RECCO® Rescue System.  Any clothing or equipment which displays the RECCO® Reflector, which is a self contained and maintenance free device







means in the event of an avalanche rescuers can locate you easier and quicker and with pin point accuracy.  Clearly a potentially life saving addition which underlines the types of activity Helly Hansen have anticipated the wearer to be involved with.

The jacket comes three different colours; Clementine (On test), Ebony and Apple Green.  It retails at around the £300 mark which for a jacket as versatile as this must be considered a shrewd investment.  Helly Hansen manufacture utility wear for survival, work and sport, focusing on the needs of professionals, athletes and enthusiasts as their core values.  These values radiate out into their clothing and equipment, the Odin H2Flow Jacket being no exception.

We’ve already spent a few weeks with the Odin H2Flow Jacket and will bring you more details over the coming months.  Until then, please refer to the “First Impressions” tab for further information or visit the Helly Hansen website for more details:

Like the Sirens who lured sailors to their doom, if you don’t avert your eyes the Odin H2Flow Jacket will make you drunk with desire.

Is this all about aesthetic eye candy or is there real substance lurking beneath its pretty shell; lets find out…

I have lost count as to the number of shell jackets I have owned over the years and at first glance, and as a self-confessed addict, I thought this would be just another notch on the walking poles…  how very wrong I was.

When unpacking the Odin H2Flow I was initially struck by the undeniable quality and detailing that has gone into the manufacturing process such as the water resistant two-way main zip:

Aquaguard pocket and pit-zips:

Both of which have mesh inserts to maximise airflow if things become a little heated.







The H2Flow insulation system utilises air pockets in the back of the jacket with carefully placed insulation within the pockets.







The concept is based on insulation that uses air to provide the warmth with strategically placed air vents to equalise the temperature when on a difficult ascent…genius!

The addition of a zip out snow skirt in the bottom of the jacket gives the jacket real versatility so it can be used in a lot of different outdoor activities easily.

This encompasses what Helly Hansen is all about for me, adaptability and versatility giving real value for money.  You could be trekking one day and ski-ing the next, without any compromise in terms of quality or performance.



The in built RECCO® Reflector provides a little welcome reassurance and is must for any winter adventurer.







The RECCO® Rescue System is two-part technology. Ski resorts and rescue teams carry RECCO® detectors. The detector sends out a directional search signal, which is echoed by RECCO® reflectors worn by skiers, riders and other outdoors people.

These things are virtually indestructible, require no batteries or training for operation.  You should be happy in the knowledge that’s it’s always on, can’t be forgotten and whilst it’s not replacement for common sense or taking the usual precautions, it’s good to know that manufacturers like Helly Hansen are looking out for you.  Certainly a consideration when making your next purchase.

The jacket has a fully adjustable helmet compatible hood design.

The single handed – glove friendly – operation is superb for for hi-octane activities where speed is of the essence.  The peak have slight reinforcement which is ideal for a jacket of this type and when adjusted provide good levels of protection.  Fit, form and function are excellent whilst comfort remains paramount.

Moving on to the extremities; both the hem and cuffs are adjustable, providing good levels of protection from the elements.

The one thing that amazes me with this jacket is its weight, or lack of.  For a jacket of this type offering all of its inherent versatility, you’d expect it to tip the scales well in excess of it’s 760grams.  Now, we’re not saying this is light but I can think of several pure shell jackets that come in at or above the weight of the Odin H2Flow.  For a jacket that feels as robust as this and can operate in numerous climates and situations, I think that’s a real plus point.

  • Waterproof and breathable Helly Tech Performance membrane with DWR coating
  • H2 Flow insulation and venting system with underarm zips
  • Welded Aquaguard YKK zippers
  • Fully-taped seams
  • Zip-out powder skirt
  • Helmet compatible hood design.
  • Bottom Hem elastic adjustment
  • Harness and pack compatible design
  • Recco reflector system
  • Pit zips
  • Adjustable cuffs
  • One handed hood adjustment
  • Solid 2ply laminate construction
  • 760G weight

H2Flow allows you to control your body’s temperature. The insulation concept uses air to provide warmth and ventilation and lets you control the airflow that cools you down when necessary.


For high intensity challenges in any weather conditions Helly Tech® PERFORMANCE gear will keep you dry, comfortable and confident throughout your adventure. Specifically designed Helly Tech® PERFORMANCE fabrics deliver sport specific performance with high waterproof and breathability ratings to keep you comfortable and focused on your challenge. All seams are fully taped for optimum waterproof performance.

As a self-confessed jacket addict, I’ve owned and examined more jackets than I care to remember.  That said, the Odin H2Flow Jacket has really impressed me; it’s the design excellence, attention to detail and quality that sets this apart.  Setting new levels of versatility at a price I think is highly competitive, the Odin H2Flow is definitely worth the investment if you’re looking for more than just single application.
