Why We Like The Odin Mountain Infinity 3L Shell Jacket

The Helly Hansen Odin Mountain Infinity 3L Shell Jacket was developed and field tested in extreme conditions, from the Himalayas to the Antarctic Ocean, to give not only mountain guides the right gear, but also regular Joes like us. LIFA INFINTY PRO™ takes environmental responsibility to the next level with the evolution of the LIFA fiber to create a durable and hydrophobic face fabric without the use of a DWR coating. Paired with a chemical and solvent-free LIFA INFINITY™ membrane delivering top-notch waterproof-breathable performance, LIFA INFINITY PRO™ delivers everlasting waterproof protection without the use of chemicals or needing to be reproofed.


  • Lightweight technical shell for arduous mountain pursuits
  • Layer-ready fit provides room for layering and easy mobility
  • Fully waterproof material is durable without added chemicals
  • Extra-large front pockets store all your essentials
  • Detachable powder skirt boosts protection in deep snow
  • Underarm zippered ventilation dumps heat on high-output activities
  • RECCO reflector can helps in the event of an emergency
  • Runs small, so we recommend sizing up for ideal fit

Size up if you have broad shoulders

I've used it once or twice and have initial impressions
Size Bought:
5' 6"

I’m usually a small (I’m 5’6 and 125 lbs and don’t have boobs and my torso is longer/lean), but I sized up and got a Medium because I figured I’d be packing layers underneath. However, I have broad shoulders for my frame (I used to swim, but also just naturally have broader shoulders). I can still layer underneath, but it is a little tight on my shoulders. There is plenty of room in the stomach area still, and I have LONG arms and the arms are pretty long on the medium. If you have boobs/wide shoulders, you should probably size up, but be careful if you have short arms/limbs.

Grabbed this jacket on killer sale even though I couldn’t find many reviews online so ordered two sizes to try. Fits true to size. I’m 5’4” around 115-120 and wear XS in Patagonia and the XS fits perfect with room to layer. My thinner and thicker Patagonia down jackets both fit under for layering without restricting arm movement. Love the grey color. Hood fits over my helmet. Perfection. Now it’ll just have to hang in my closet waiting for winter!
