But with so many rain jackets on the market—and with prices that can make you think twice—is the Helium Rain Jacket actually worth it? If you’re considering this jacket for your next adventure, or just for daily use, you’re in the right place.

The Outdoor Research Helium Rain Jacket is a lightweight, waterproof, and windproof shell made for people who want to move quickly and travel light. It’s popular with ultralight hikers, bike commuters, and anyone who needs a jacket that won’t weigh them down. The Helium is often listed in guides for best rain jackets, especially for those who count every ounce.
Outdoor Research first released the Helium in 2011, but it’s been updated several times. The most recent versions use Pertex Shield Diamond Fuse fabric, which is designed to be stronger and more durable than older models, without adding weight.

- Zippers: YKK AquaGuard water-resistant zippers
These numbers and features matter, but what do they mean in real life? Let’s break it down by what matters most to outdoor users.
Waterproof Performance: Does It Actually Keep You Dry?
A rain jacket’s main job is to protect you from rain. The Helium’s 20,000 mm waterproof rating means it can stand up to heavy rain. In real-world use, hikers report that it keeps them dry in everything from light drizzle to steady downpours. The water beads up and rolls off, thanks to the DWR (durable water repellent) coating.
But, like all 2. 5-layer jackets, it’s not the best for hours of heavy, driving rain. If you’re planning multi-day trips in wet climates (like the Pacific Northwest), you might want a heavier 3-layer jacket. The Helium is best for quick storms or as an emergency shell.

Breathability: Can You Stay Comfortable?
Breathability is key if you’re moving fast or working hard. The Helium’s 20,000 g/m²/24hr breathability rating is good for this weight class. During normal hiking or walking, most people don’t feel clammy inside. But if you’re trail running or hiking uphill with a heavy pack, you’ll likely get sweaty. The Helium doesn’t have pit zips or venting hand pockets, so it can trap heat in intense activity.
Non-obvious insight: Wearing breathable base layers underneath helps a lot. Many new users expect breathability to be magic, but it works best as part of a full layering system.
Weight And Packability: A Standout Strength
At just over 6 ounces, the Helium is one of the lightest full-featured rain jackets available. It packs down to the size of a large apple, making it perfect for stuffing into a daypack, running vest, or even a bike saddlebag.
For travelers, it’s a smart “just in case” option that won’t add bulk or weight.
Here’s a quick look at how the Helium compares to some other popular ultralight rain jackets:
| Jacket | Weight (Men’s M) | Packs Into Pocket? | Waterproof Rating (mm) |
|---|---|---|---|
| Outdoor Research Helium | 6.3 oz | Yes | 20,000 |
| Patagonia Houdini | 3.7 oz | Yes | Water resistant |
| Montbell Versalite | 6.4 oz | Yes | 30,000 |
| Arc’teryx Beta SL | 10.6 oz | No | 28,000 |
As you can see, the Helium holds its own among top ultralight choices, and offers true waterproofing unlike some “wind jacket” alternatives.
Durability: How Tough Is The Helium Rain Jacket?
Ultralight jackets are often fragile, but the latest Helium uses Diamond Fuse technology. This fabric weaves diamond-shaped filaments together, which makes it more resistant to tearing and abrasion.
Many users report years of use, even with regular stuffing into packs or pockets. However, the jacket is still thin, so bushwhacking through thorny brush or scraping on rough rock can cause damage. It’s not made for hardcore mountaineering, but it’s tough enough for most trails, city use, and travel.
Tip: If you often hike off-trail or carry heavy packs, consider adding a patch kit to your gear. Small tears can be fixed easily, and this extends the life of your jacket.
Fit And Comfort: How Does It Feel?
The Helium has a trim athletic fit, but it’s not super tight. Most people can wear a base layer and a light midlayer underneath. The jacket is cut longer in the back, which helps keep you dry when bending or sitting.
The hood is roomy and adjustable, fitting over a baseball cap or lightweight helmet. Some users with larger heads wish it was slightly roomier, but most find it works well.
Elastic cuffs and a drawcord hem help seal out drafts. Because the fabric is thin, it feels light and flexible, not stiff or crunchy like some cheaper rain jackets.
Everyday Use: Is It Good For More Than Hiking?
The Helium isn’t just for mountain trails. Many people use it for:
- Bike commuting: Packs small, doesn’t flap in the wind, and offers good coverage.
- Travel: Fits in any bag, ideal for cities with unpredictable weather.
- Running: Light enough for most runners who want rain protection.
- Emergency kit: A solid backup shell for your car, office, or backpack.
It’s not as stylish as some urban rain jackets, but the simple design and color options work for most casual situations.
Limitations And Trade-offs
No rain jacket is perfect. Here’s where the Helium falls short for some users:
- No hand pockets: Only one chest pocket, which can be awkward for hands or storing bulky items.
- No pit zips: Breathability is good, but without pit zips, it can get warm during high effort.
- Not for heavy, all-day rain: For all-day storms, a heavier 3-layer jacket is better.
- Fit may be snug for layering: If you want to wear thick layers underneath, consider sizing up.
Some people wish for more features, like multiple pockets or tougher fabric. But adding these would raise weight and price, so it’s a clear trade-off.
Price And Value: Is It Worth The Money?
The Helium usually sells for $160–$180 (MSRP), but it’s often found on sale for less. For an ultralight, waterproof, and durable jacket, this price is competitive. Cheaper jackets exist, but often weigh more, breathe less, or aren’t truly waterproof.
Let’s see how the Helium’s value stacks up against similar jackets in its class:
| Jacket | Price (MSRP) | Weight | Best For |
|---|---|---|---|
| Outdoor Research Helium | $159 | 6.3 oz | Ultralight hiking, emergency use |
| Patagonia Torrentshell 3L | $179 | 13.9 oz | Daily rain, durability |
| Arc’teryx Beta SL | $299 | 10.6 oz | Serious rain, all-day use |
| Frogg Toggs Ultra-Lite2 | $20 | 6.4 oz | Budget, occasional use |
The Helium isn’t the cheapest, but it’s a strong value for what you get. You’re paying for the right mix of low weight, solid waterproofing, and better-than-average durability.
Real-world User Feedback
Online reviews and field tests provide good insight into how the Helium performs for real people. Here’s a summary of common opinions:
What users love:
- “So light, I forget it’s in my pack.”
- “Kept me dry on a 12-mile hike in Oregon.”
- “Packs down to nothing—great for cycling and travel.”
- “Survived several falls and scrapes—tougher than it looks.”
Common complaints:
- “I wish it had hand pockets.”
- “Gets sweaty on uphill climbs—pit zips would help.”
- “Not warm, just a shell—need layers underneath.”
- “DWR wore off after a season, but was easy to reapply.”
Most users rate it highly for its intended use: light, packable, and waterproof for short to moderate rain. Those who expect more features or heavy-duty protection often find it lacking.
Who Should Buy The Helium Rain Jacket?
The Helium isn’t for everyone, but it’s an excellent choice if you:
- Value low weight and packability more than extra features
- Hike, bike, or travel and need emergency or backup rain protection
- Don’t want to spend $300+ on a high-end technical shell
- Are careful with gear and don’t need to bushwhack often
It’s less ideal if you want lots of pockets, plan to wear it for hours in constant rain, or need a jacket for winter sports. For those cases, a heavier or 3-layer jacket is better.
Care And Maintenance Tips
To keep your Helium working well, follow these care tips:
- Wash with mild detergent (no fabric softener) to remove dirt and sweat.
- Tumble dry on low or air dry to reactivate the DWR coating.
- Reapply DWR spray every few months or if water stops beading.
- Store dry and loose—not stuffed for long periods.
Taking care of the jacket not only keeps it waterproof but also extends its lifespan.
Comparison: Helium Vs. Other Outdoor Research Jackets
Outdoor Research makes several rain jackets. How does the Helium compare to its stablemates?
| Jacket | Weight | Fabric | Best Use |
|---|---|---|---|
| Helium Rain Jacket | 6.3 oz | 2.5L Pertex Shield | Ultralight, backup |
| Foray II Jacket | 16 oz | GORE-TEX Paclite | All-day rain, hiking |
| Interstellar Jacket | 11 oz | Ascentshell 3L | High activity, breathability |
| Motiv Jacket | 9.2 oz | Pertex Shield 2.5L | Trail running, hiking |
The Helium is the lightest and most packable. For more features or heavier rain, OR offers thicker, more expensive shells.
Environmental Impact
Outdoor Research has made efforts to improve the sustainability of its products. The Helium’s DWR coating is PFC-free, which is better for the environment than older chemical treatments. The company also uses bluesign-approved fabrics, meaning they meet strict safety and environmental standards.
While the jacket isn’t made from recycled materials, it’s built to last. Using gear for many years, rather than replacing it often, is one of the best ways to reduce waste.

Frequently Asked Questions
Is The Helium Rain Jacket Good For Winter?
The Helium is a shell only—it’s not insulated. You can wear it over warm layers for wind and rain protection, but it won’t keep you warm by itself in winter. For cold, wet conditions, pair it with a fleece or insulated jacket underneath.
Can The Helium Rain Jacket Handle Heavy Backpacking Use?
It’s tough for its weight, thanks to Diamond Fuse fabric, but it’s still a thin jacket. If you’re carrying a heavy pack on long trips, shoulder wear can happen over time. For regular, heavy backpacking, a 3-layer or thicker jacket may last longer.
How Do I Restore The Dwr Coating?
When water stops beading up, wash the jacket with mild soap, rinse well, then tumble dry on low to reactivate the DWR. For best results, use a spray-on DWR product made for outdoor gear.
Is The Helium Rain Jacket True To Size?
Most users find the fit true to size, with room for a base layer and a light midlayer. If you want to wear thick sweaters or down jackets underneath, consider sizing up.
What Is The Warranty On Outdoor Research Jackets?
Outdoor Research offers the Infinite Guarantee, which covers defects and workmanship for the lifetime of the product. They are known for excellent customer service and easy repairs or replacements.
Final Thoughts: Is The Helium Rain Jacket Worth It?
If you want a rain jacket that’s ultralight, packable, and reliable for most outdoor adventures, the Outdoor Research Helium is one of the best in its class. It’s not the most feature-rich, but it does exactly what it promises—keeps you dry without weighing you down. The price is reasonable for the performance and durability you get. If you understand its strengths and limitations, and use it for the right situations, you’ll likely find it a smart investment that lasts for many seasons.
