How to use: You can wear the Atom Hoody on its own when the weather is a bit chilly, like during forest hikes or climbing. For colder or wetter conditions, layer it under your outer jacket. Just zip it up, adjust the hood if needed, and you're good to go. Things to note: Avoid sharp objects that could tear the jacket. While the Coreloft insulation is good in light weather, don't expose it to heavy rain or snow for a long time. Maintenance advice: Wash the jacket according to the care label. It's usually best to use a mild detergent and a gentle cycle. Hang it to dry instead of using a dryer to keep the insulation in good shape.
