With the next snowmobiling season just around the corner, I had the opportunity to put the 509 Ether non-insulated two-piece suit, consisting of a jacket and bibs, to the test, along with the 509 Raid Double BOA backcountry snowmobile boots.
When it comes to backcountry snowmobiling, anyone familiar with the demanding conditions that riding gear must withstand knows just how important it is to make the right choices!
Backcountry enthusiasts understand this all too well. They know the importance of investing in quality gear that is comfortable, durable, and capable of effectively managing moisture and perspiration during intense physical activity.
That’s exactly what 509 aims to deliver with its Ether two-piece suit, which is also available in a one-piece version!
At first glance, the Ether jacket and bibs certainly have a lot going for them! Both pieces look fantastic and offer plenty of practical features designed to meet the demands of backcountry riding.
There are just enough storage pockets, both inside and out, to carry your phone, radio, and other personal belongings.
It’s also worth mentioning that the other colour options offered by 509 are equally attractive and modern!
Technical Features of the 509 Ether Jacket and Bibs
Both pieces are primarily constructed using a Sympatex membrane rated at 45,000 mm / 25,000 g, along with high-quality materials such as YKK zippers, which can be found throughout the suit.
To better understand what these numbers mean, it’s worth taking a closer look at the technical specifications and the benefits they provide.
| Rating | Meaning | Details |
|---|---|---|
| 45K | Waterproofing (hydrostatic head) | The membrane can withstand water pressure equivalent to a 45,000 mm water column before allowing water to penetrate. This represents an extremely high level of waterproofing, more than sufficient for heavy rain and wet snow. |
| 25K | Breathability (MVTR) | A moisture vapour transmission rate of up to 25,000 g/m²/24 h, allowing substantial amounts of body moisture to escape. This is especially important for staying dry during intense physical activity. |
To put these technical terms into simpler language, the Sympatex membrane used by 509 is an alternative to Gore-Tex, a technology widely recognized in the snowmobile apparel industry.
With its advertised 45K/25K ratings, Sympatex offers excellent waterproofing and breathability. However, direct comparisons with Gore-Tex depend on the specific membrane and garment construction.
509 Ether Jacket and Bibs: My Real-World Riding Impressions
But what about durability and fit? Has 509 developed a jacket and bib combination that truly meets the needs of demanding backcountry snowmobilers?
Based on my testing, the Ether suit delivers performance that meets the standards long established by Gore-Tex-equipped snowmobile clothing.
However, where the Ether lineup falls a little short is in certain aspects of fit and design that may disappoint more demanding riders.
Let me explain!
A Unique Fit That Makes Trying It On Essential
The Ether jacket and bibs feature a rather unusual cut that doesn’t necessarily follow standard sizing!
For this reason, I strongly recommend trying the suit on in a store before purchasing it online.
Both the jacket and bibs have some questionable body proportions.
For example, if you’ve been wearing a medium for years, as I have, you might suddenly find yourself needing to move up a size because the sleeve and leg lengths simply don’t fit properly!
I would even recommend trying the suit on while wearing your snowmobile boots and gloves.
Personally, I would have appreciated a little more flexibility around the sleeve cuffs and lower leg openings.
As a result, I found the overall comfort of the suit to be somewhat average when wearing my usual size.
Durability and Wear Resistance in Backcountry Conditions
When it comes to wear resistance, I encountered an issue fairly early in my testing.
The attachment loop designed to secure the engine tether tore during use.
In addition, the reinforced knee protection on the bibs suffered a few snags.
However, I want to emphasize that the clothing was tested in some fairly demanding Québec backcountry conditions!
I’m talking about thick, messy woods filled with tightly spaced spruce trees!
Anyone who rides in these conditions knows exactly what I’m talking about!
Protection and Comfort of the Ether Bibs
When it comes to accommodating additional protection for the lower body and legs, the Ether bibs perform well and provide good support.
Padded protective shorts can also be worn comfortably underneath.
The jacket can accommodate an additional insulating liner when needed, which is particularly useful in colder weather.
Keep in mind, however, that the insulating liner is not included with the jacket.
509 Raid Double BOA Boots Review
At first glance, the 509 Raid Double BOA boots are considered among the leading options for backcountry snowmobiling.
Featuring 600 grams of Thinsulate insulation, these boots fall into the moderately insulated category.
They are very comfortable, provide good waterproof protection, and offer breathable properties.
However, choosing the right socks is essential to maximize their overall performance.
The outsole is solid and resistant to wear.
Double BOA System and Boot Stiffness
The Double BOA closure system works very well, and I experienced no issues loosening the boots, even in cold weather.
However, these are fairly bulky boots with a large upper opening.
This can make it more challenging to pull the lower portion of your snowmobile pants over the boots.
Three colour options are available: Black, Black Gum, and my personal favourite, Sharkskin!
These are also among the stiffest snowmobile boots you’ll find on the market.
You’ll either love that stiffness or you won’t!
Final Verdict: Are the 509 Ether Suit and Raid Double BOA Boots Worth It?
While I certainly wouldn’t go as far as saying that riders should avoid the Ether suit altogether, we recommend the 509 Ether jacket and bibs, along with the Raid Double BOA boots, to those who take the time to try them on in person before purchasing.
The Ether suit has a fitted design that offers somewhat less freedom of movement than some competing products.
The membrane materials provide excellent breathability and help regulate body temperature during physically demanding rides!
It’s also important to remember that staying warm requires proper layering.
Since the jacket and bibs are essentially non-insulated shells, riders should plan to wear appropriate insulating mid-layers, such as fleece, depending on the weather conditions.
Certain stitching details, particularly around attachment points such as the engine tether loop, could benefit from improvement.
Personally, I also would have appreciated a small hook near the collar for attaching a radio.
We believe that the non-insulated Ether suit and Raid boots with 600 grams of insulation are primarily designed for active backcountry snowmobilers.
In my opinion, the Ether is one of the best-looking two-piece snowmobile suits on the market.
And when it comes to the boots, the Sharkskin, red, and black colour combinations are easily among the most attractive available!
