Naming System
Arc’teryx product names typically follow a two-part format, such as “Beta AR,” as shown above. In this naming, Beta is the PRODUCT FAMILY, and AR is the PRODUCT MODIFIER. For easier understanding, we’ll refer to them as “Purpose” and “Material” in this blog.
PURPOSE: Product Family
The first part (e.g., Beta, Atom) categorizes the product based on its intended use. For example, the Alpha model is designed for professional climbers and is ideal for alpine climbing.
MATERIAL: Product Modifiers
The second part (e.g., AR, LT, SL, FL) represents the material characteristics. For instance, SL stands for Super Light, meaning it’s extremely lightweight and highly packable.
This naming system supports layering for optimal performance.
Layering System
Layering helps regulate body temperature and improve overall comfort and performance. It consists of three main layers: outer, mid, and base. Referencing layering when choosing your gear helps you pick the right product.

Outer layer is the most exposed and offers durability and protection. Mid layer retains heat and adds flexibility. Base layer is worn next to the skin and is lightweight, soft, and moisture-wicking.
Choosing by Purpose
The table below provides a simple summary of Arc’teryx product layering by purpose. Red indicates outer layers, yellow indicates mid layers, and green indicates base layers. Products like Beta are designed to be worn as outermost layers. Because they’re suitable for all types of sports, it’s a great choice if you’re only getting one jacket.

Choosing by Material
Once you’ve chosen your purpose-based product, consider the conditions you’ll use it in. Heavier jackets are warmer (and pricier), while lighter ones are more affordable but less insulating. For a quick overview, here’s a breakdown of key modifiers like AR, LT, SL, and FL.

Differences in Beta models by intended use (AR, LT, Jacket)

Arc’teryx Beta Exterior and interior
Photos of each model’s inside and outside are shown above. For example, the Beta AR logo can be seen on the internal pocket. Note that details may vary slightly depending on production year and manufacturing location. Models like AR and SL feature pit zips, which are useful during hikes or high-activity scenarios.

Hood types
Drop hoods are more convenient for daily wear. They often feature a smooth finish around the collar for comfort. Storm hoods are more secure in harsh winds and weather.
