Update: Our in-depth comparison of the Arc'teryx Atom SL (Atom Lightweight) vs the Proton Lightweight (formerly Proton FL) can be found at https://outdoorcrunch.com/arcteryx-proton-vs-atom/.
Proton FL.
Now that the summer is here, let's take a look at how the differences between Proton FL vs Atom SL play out.
Atom SL (Super Light) and Proton FL (Fast & Light) are the two most breathable, least warm alternatives you can find in Arc'teryx's insulated jacket line-up.
They're both best suited for chilly summer and/or spring mornings, followed by a high output activity (primarily rock / alpine climbing).
These jackets are more alike than they're different.
- Proton Lightweight (FL) is a bit more durable, a bit more comfortable and is an inch longer
- Atom SL is a bit more breathable

Neither of these jackets will provide substantial warmth. Like I clarified earlier, they aren't even designed to do so anyway.
Proton FL is insulated with Octa Loft throughout the entire jacket. The Atom SL, on the other hand, is insulated with Coreloft Compact only around the core, which holds it warmth back.
I'd recommend you to take a look at the lowest temperatures they're expected to be worn comfortably by an average person (both are positioned at the bottom):
