You can grab one of Arc’teryx’s most popular waterproof shells for up to 40% off — if you’re flexible on color.
Among outdoor enthusiasts, Arc’teryx’s Beta jacket lineup has earned a reputation as one of the best-performing shell collections available.
While generally more affordable than the brand’s legendary Alpha series, Beta jackets still sit firmly in premium territory. Their combination of technical performance, lightweight construction, and refined design often puts them at a price point that only serious climbers, mountain professionals, or dedicated gear enthusiasts are willing to pay without hesitation.
But right now, there’s a rare opportunity.
Thanks to REI, one of Arc’teryx’s lightest and most versatile waterproof jackets — the Beta SL — is available at a significant discount.
If you don’t mind choosing from select color options, you can save as much as 40% off the regular price.
A premium alpine shell at a rare price
Let’s start with the numbers.
The Arc’teryx Beta SL normally retails for $500.
However, REI is currently offering the men’s version for $300 in select colors, while the women’s version is discounted to $410.
Available discounted colorways include:
- Men’s Mantis/Tatsu — several sizes still available
- Men’s Vitality II — limited sizes remaining
- Women’s Dynasty/Carmine — most sizes available
Availability is expected to change quickly, especially since Arc’teryx products rarely receive major discounts.
Lightweight performance for the mountains and beyond
The appeal of the Beta SL becomes even stronger when discounted because it delivers serious technical performance while also fitting naturally into everyday outdoor-inspired style.
The jacket’s popularity comes from the same reason many Arc’teryx products have become favorites among hikers, climbers, and the broader “gorpcore” community:
It performs extremely well outdoors, but it also looks at home around town.
Of course, performance remains the primary focus.
Arc’teryx designed the Beta SL as a lightweight mountain shell capable of handling unpredictable weather without adding unnecessary weight.
Waterproof, breathable, and built for movement
The Beta SL weighs only:
- 10.6 ounces for women’s size small
- 12 ounces for men’s size medium
Despite its minimal weight, it provides full weather protection thanks to a PFC-free GORE-TEX ePE membrane and comfortable C-KNIT backer construction.
The result is a jacket that is:
- Waterproof
- Windproof
- Breathable
- Comfortable for extended wear
Whether you’re hiking through heavy rain, climbing in changing conditions, or traveling with limited luggage space, the Beta SL is designed to handle demanding environments.
Thoughtful details for serious outdoor use
The jacket features Arc’teryx’s StormHood, which is fully adjustable and helmet compatible.
When conditions turn harsh, the hood can be tightened to create a secure fit around the head and face while maintaining visibility.
The trim athletic cut keeps the jacket close to the body without restricting movement, helping reduce bulk when worn under additional layers.
Additional adjustment points include:
- Velcro cuffs
- Adjustable waist cinch
- Articulated fit for better mobility
Built for high-output adventures
One of the most important features for active users is ventilation.
The Beta SL includes large underarm pit zippers that can be opened quickly to release excess heat during intense activity.
Because they remain accessible while wearing a backpack, they’re especially useful for hiking, climbing, and backcountry travel.
The jacket also includes:
- Zippered hand pockets
- Internal chest pocket
- RECCO reflector for improved search-and-rescue visibility in emergencies
A rare chance to own premium Arc’teryx gear for less
Arc’teryx rarely discounts its most popular technical pieces, making this Beta SL deal especially appealing.
At full price, the jacket represents a serious investment. But at up to 40% off, it becomes much easier to justify for anyone looking for a lightweight, reliable shell that can handle both mountain adventures and everyday weather.
The only catch?
You may have to compromise on color.
But for one of the best lightweight waterproof jackets Arc’teryx makes, that might be a trade-off worth accepting.
