Lightweight is an understatement with this jacket, but don’t let its featherweight design fool you–the Outdoor Research Helium jacket is for real and not only for the “just in case” moments. The Pertex Shield fabric is light and seemingly-durable in spite of its thin-ness. It also breathes extremely-well. After a hard 30-minute run on a 45-degree day the Helium merely felt slightly damp to the touch on the inside. After 5 minutes, that had all dissipated.
The cut of the jacket is great for slapping on top of a down jacket or other puffy insulation layer as need arises. Alone with only a long-sleeve shirt underneath, I’d wish for a little more form-fitting torso. As it stands, it works great on top of puffier under layers. The hem is cut longer than many jackets of this type, so it covers your backside well even when you’re moving around a lot. The simple elastic sleeve cuffs are simple and light, but a lightweight Velcro cuff would have been great.
I brought this jacket along on a handful of ski tours as well and loved the light weight and compressibility of this jacket. Stuffing it into the bottom of my backcountry ski pack, it yielded plenty of space for other sundries.
I really dig the hood and find it necessary in a jacket like this. Should you need to slap it on in a pinch, the hood can be easily worn–leaving your noggin well-protected.
As time goes on, I still marvel at how lightweight this jacket is yet how performant it remains. Excellent overall design for “just in case” backcountry use or highly-aerobic activities.
- So light it will amaze you
- Excellent water and wind protection
- Pertex Shield fabric is really the star of the show
- Attached hood adds to the versatility
- The Fossil color is muted and dashing
- Very lightweight and packable
- Single-handed shock-cord hem cinches well
- Missing some sort of grippy rubber along the inside of the hem to keep in place
- No hand pockets
- Front zipper is reversed (for the ladies?)
- Would like to see a simple Velcro cuff closure instead of just elastic
Bottom Line: Outdoor Research Helium Jacket
While some great Outdoor Research jackets are sometimes overlooked, the Helium should garner several double-takes. It’s light weight, packable and offers solid shelter for aerobic activity or in a pinch. The Pertex fabric breathes well and performs when needed.
