Why Choose the Beta SL Jacket?
The new Arc'teryx Beta SL Jacket is light and packable. It delivers complete waterproof, windproof, and breathable protection. Moreover, this jacket has been redesigned. It features an innovative GORE-TEX ePE membrane. This light, strong, PFC- and PFAS-free piece features a C-KNIT backer for comfort and breathability. The helmet-compatible StormHood adjusts to pivot with my head while maintaining my vision. WaterTight zippers seal securely. Pit zips vent heat. Additionally, a RECCO reflector in the hood aids search efforts.
Previously known as the Beta Lightweight Jacket, this updated version uses a lighter, thinner membrane. Yet, it remains just as durable. At 340g, it fits in its chest pocket and is ideal for emergency weather protection. The trim fit works great with my 6-foot, 165 lbs frame. It is worth noting that the fabric may wear out more quickly in heavy rain.
I always wanted to own a Beta jacket. And recent travels to the PNW gave me a great excuse. So, I dipped my toe in the Beta family with this light version. There is no chance to shop for this on the secondary market because it is riddled with fake jackets selling for close to retail price. I will take very detailed pics, then write an article on how to do a legit check.

The Evolution of Arc’teryx Beta Lightweight Models
Arc’teryx launched the Beta series in 2000. They were versatile Gore-Tex hardshells for all-around use. Additionally, the lightweight variants prioritized packability and breathability. This suited hiking, alpine pursuits, and variable conditions.
The Beta LT emerged in the early 2010s as a balanced option. It featured N40p Gore-Tex Pro fabric, pit zips, helmet-compatible StormHood, and a trim fit. It weighed around 395g. Yet, it offered solid durability for multi-season adventures.
By the early 2020s, Arc’teryx refined the line. Consequently, the Beta Lightweight succeeded the Beta LT. It incorporated a C-Knit backer for a softer feel and better breathability. Along with that, minor updates included RECCO reflectors and adjusted pockets.
In 2024–2025, sustainability drove major changes. Therefore, the model was rebranded as Beta SL (Super Light). It adopted a PFC-free Gore-Tex ePE membrane that is lighter, thinner, and more eco-friendly without compromising waterproofing. Hybrid 40D/70D face fabric enhanced abrasion resistance in high-wear areas. Today, the Beta lineup includes the minimalist Beta, versatile Beta SL, and burly Beta AR.
