Lighter than the original, the Atom SL Hoody is one of the most useful (and packable) pieces you can own. Wear it as a standalone layer when trail runs take you through cold, wet weather or layer it with a waterproof shell when mountain pursuits demand additional warmth and mobility. Breathable and weather-resistant, it has stretch insulation in the body but not the sleeves or hood — maximizing packability while still delivering focused warmth to your core.

Updated with recycled Fortius™ Air 20 fabric, recycled stretch synthetic insulation, and FC0 DWR finish for improved mobility and a lower footprint.

Solid Shoulder Season Piece
Thinner than previous iterations of the Atom SL but certainly a good addition to quiver. The forearm material on the underside is very thin so I'm not sure I'd want to use this on a rock or rough surfaces but as far as general wear, hiking and other non contact mountain adventures this is excellent. The perfect shoulder season jacket to grab when running out the door. The new lightweight side mesh panels are excellent and feel sturdy. For reference the fit is just slightly loose yet fitted. Wearing a size medium, 5'6" 150lbs athletic build. Please bring back an ATOM SL vest in this material!

No Chest Pocket!
No chest pocket. So if you’re wearing a pack of vest the only pockets available are practically useless. This is a common thing on Arc’teryx ‘women’s’ items. Somehow I missed that in the pictures and was excited to get a piece this weight but will be returning it now.

Sleeves Are Too Long.
I have two Atom Vests, which I love, so I thought I'd try the hoody. The sleeves were too long! If the elastic at the end of the sleeves went all the way around, I could make it work. But the elastic only went half way around, so there was no getting the sleeve ends out of the way. I had to return it. Another solution would be for Arcteryx to start carrying Petite sizes for women. Please consider it! That would make me soooo happy!

The One Jacket I Keep With At All Times!
My favorite jacket by far. I use it touring on the uphill, on cold days hiking in the fall, paddling when the air is crisp, mountain biking and long days on the road bike going over mountain passes. I also get a lot of compliments on the look of this jacket. One thing I love is when I'm using my watch for navigation this style of sleeve allows for the watch to be easily accessible. I wish the other Atom jackets had the same sleeve, as I would definitely buy them but the tightness around the wrist of the other Atom jackets makes it frustratingly impossible to use a watch. Super light weight and water resistant too! For reference I'm 5'8" 128lbs with small bust and it fits me perfectly.

A Year-round Staple
I had an older version of this and I love the updates. The fabric is stretchier and while still as warm, it has fewer seams and is somehow less bulky. This jacket stretches and moves really well (which is nice for someone with hips and for arm movements, especially when climbing). This lightweight hoody is my year-round go-to. In the summer, it's easy to throw on for a cold evening and in the colder seasons it's a great layer, especially for skinning. I have broad shoulders and generally wear a small in Arc'teryx jackets.
