  • Material: Constructed with a heavier, more robust nylon blend to enhance durability and weather resistance. The built-in rain cover offers added protection, reducing the need for disposable rain gear and promoting sustainable practices.

Both series offer a range of features designed to enhance your outdoor experience, but the choice ultimately depends on your preferences and the demands of your adventures.

Performance in Various Conditions

Cold Weather

Atom LT:

  • Superior Warmth: With its Coreloft Compact 60 g/m² insulation, the Atom LT is designed for winter hikes, mountaineering, and other cold-weather activities. The robust shell provides exceptional thermal protection, ensuring warmth in freezing conditions. Additionally, its fit allows for layering over a base layer or under a heavier shell for added insulation.

Atom SL:

  • Cool Summer Nights: The Atom SL, with its lighter Coreloft Compact 40 g/m² insulation, is perfect for milder conditions such as cool summer nights. It serves well as a light insulating layer during high-exertion activities, keeping you warm without overheating. This makes it suitable for moderate temperatures and active pursuits like summer hiking or early fall camping.

Wet Conditions

Atom LT:

  • Better Rain Repellence: The Atom LT offers superior rain protection due to its thicker insulation and more substantial shell treated with a durable water repellent (DWR) finish. This combination makes it more effective in wet conditions, keeping you dry longer compared to the SL. Its design ensures that even in unexpected downpours, you remain protected from the elements.

Atom SL:

  • Light Rain Protection: Designed to handle light rain and damp conditions, the Atom SL features a lighter shell and lower insulation level. This design makes it less suitable for heavy downpours but adequate for short, mild showers. Its lightweight nature allows for quick drying and minimal water absorption, making it a practical choice for damp but not wet conditions.

High-Exertion Activities

Atom SL:

  • Optimized for Breathability: The Atom SL excels in high-exertion activities where breathability and lightweight performance are crucial. Its design, featuring breathable fabrics and strategic insulation placement, prioritizes ventilation and mobility. This makes it ideal for activities like running, climbing, and intense hiking, where overheating can be a concern.

Atom LT:

  • Warmth Without Overheating: While the Atom LT provides significant warmth, it also effectively manages body heat during high-exertion activities. The fleece side panels and breathable construction help regulate temperature, preventing overheating while maintaining necessary warmth. This balance makes it suitable for activities that require both warmth and breathability.

Weight and Packability

Atom SL:

  • Weight: Weighing in at approximately 8.6 oz, the Atom SL is highly lightweight.
  • Packability: Its highly compressible design allows it to fit easily into small spaces like backpacks or travel bags. This makes it perfect for minimalist packing and activities requiring high mobility, ensuring it doesn’t take up unnecessary space or weight.

Atom LT:

  • Weight: At approximately 13.2 oz, the Atom LT is slightly heavier due to additional insulation.
  • Packability: While still compressible, the Atom LT is bulkier compared to the SL. It remains portable but requires more space due to its enhanced insulation. This trade-off provides additional warmth at the cost of a bit more packing volume.

Versatility and Use Cases

Atom SL:

  • Ideal for: Spring, summer, and early fall activities, high-exertion sports, and travel. Its lightweight and breathable design make it versatile for various moderate conditions and active pursuits.
  • Not Ideal for: Extremely cold or wet conditions. The lighter insulation and less robust weather protection limit its use in harsher environments where more significant thermal and water resistance is needed.

Atom LT:

  • Ideal for: Winter activities, colder climates, and as a mid-layer in extreme cold. Its superior insulation and weather resistance make it suitable for a wide range of cold-weather applications, ensuring warmth and protection.
  • Not Ideal for: Very warm weather or ultra-light packing needs. The heavier insulation can be too warm for hot conditions and adds some bulk, making it less suitable for minimalist packing.
