Chaqueta Atom SL Mujer

Love this layer style and insulation level. The Canvas color is casual enough as an urban staple, or out on the trails! I wore this all weekend working the evergreen mountainbike festival. I haven't reached for it again, since it's summer, and usually I'm a hoodie person, but I'll keep this for more professional situations in place of a blazer or midlayer.

I've been a big fan of the Atom SL since it first launched in 2016 and have owned a few generations of this piece that I love for many different use cases from ski touring to rock climbing and summer alpine running. This piece is definitely different from the previous Atom SL being lighter in weight/insulation and more breathable than the old version, but with increased packability and better next to skin feel that is very comfortable with non-restrictive for movement. Fit is similar to the older Atom, but maybe slightly longer in the torso which I personally prefer to cover my hip area. I am 5'5" 130lbs with an athletic upper body and long arms: I typically wear a size M in Arc'teryx insulation and got a M in this and it fits perfect. It almost feels like a Squamish hoody in the sleeves, but with a very light octa-loft style insulation against your body that keeps you comfy and warm but allows high output breathability when you are moving. I'm a big fan of this updated version for more summer focus as a light layer to pack for high output situations, but I think the old version is better for more spring and fall activities with slightly cooler temps. I am curious to see how the face fabric holds up to abrasion over time to compare to the old Atom SL, but is seems more like the Proton face fabric which seems more durable and resistant to catches and snags. Overall loving this updated piece for summer!

Fantastic jacket that's incredibly versatile during the warmer months but need a layer in case temperatures dip, you're along the coast, or in evenings.

Super breatheable and great fit. I usually fit between small and medium and went with medium on this peice for a more relaxed around town fit. The insulation on jacket is perfect for spring - a put it on, leave it on type of jacket. Warm enough for those cool mornings but light enough to leave on once it heats up a bit. Overall very versatile. One issue is that the face fabric pilled the first time I wore it with a backpack. That surprised me as I imagine most users with this jacket or going to be carrying packs.

This jacket is one of Arc'teryx's most versatile pieces, which is certainly reflected in how I use it. It offers just the right touch of warmth balanced with excellent breathability for high-output activities. I love how the lighter panels at the underarms let perspiration ventilate away while the insulated panels around your core conserve a little heat. For high elevation trail runs it's perfect for breezy ridges and summits, then I can peel it off once I warm back up on the descent. In the winter, I nearly always wear this jacket on the skin track, then throw a shell over it for the descent. (Add a puffy plus a shell if it's super cold.) In the shoulder seasons, it's the perfect standalone insulating layer for spring/fall trail runs and rides. Basically, this is in my pack nearly every time I leave the house to go outside. Trim fit, layers smoothly under exterior wind/rain shells.

The SL Atom is so light and breathable. I use it for winter trail running or in summer for a chilly evenings. The side is breathable yet the front stays warm with the perfect amount of insulation. The fit is flattering!
