Light, versatile synthetically insulated hoody works as a midlayer and standalone.
This fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over our first layers.
Versatile synthetic insulated mid layers with a high degree of weather resistance.
About This Item
Fit and Design
Light, soft Tyono 20 with DWR finish to repel moisture
The Atom hoody has served me well as my go-to lightweight covering for bouldering and sport across California over the last two years. It stays quite warm, especially when active, and has never left me disappointed in the Spring-Fall months. Fit runs small on broad chest/shoulders, but otherwise no complaints. I only wish it had a small stuff sack like some of the heavier Arc'Teryx jackets!

Awful
Arc’teryx is so trash now. Pretentious and quality has gone in the drain. Long gone are the days of quality craftsmanship with dependable warranties.

Perfectly Fitting All Weather Jacket
Just bought the Atom hoody jacket. The fabric feels absolutely fantastic. I wonder of the outer fabric will stay neat when I'm hiking with a backpack. I wear a size Large and this is, for me, a perfect fit even with my broad shoulders the jacket fits well. What's interesting is the breathability and insulation when you're having a walk or hike. It keeps you warm bit on the other hand, I wore it in a Stadium on a windy and chilly night and I got a bit chilly. I haven't had the chance to test the water resinstancy because it hasn't rained yet. For now a 5* review, but haven't experienced all weather conditions. But overall very happy with this jacket

When You Need Something But Nothing Too Much
I've found the Proton to be a great jacket for warming up outdoors as I'm getting ready for a tour or a run. I've also found that it's a great piece for after run / hike piece when I'm hanging outside trying to cool down but not too fast. The light insulation takes the chill away from any wind but I know I get some airflow through the sides and under the armpits where it's stretchy and less insulated. It's also great to pair with a base layer when you start your ski tour but unless it's real cold out or really breezy, this can get a bit warm as a mid-layer as you start gaining some momentum. For living up in Edmonton and going camping, other than winter, this jacket is always in the car just in case I need something during the evenings / mornings or after that outdoor workout. For winter, I wouldn't use this as a standalone piece unless I was doing something active - I would prefer something with a bit more insulation for standing around in.
