When it comes to insulated jackets, two of the most popular choices among outdoor enthusiasts are the Arc'teryx Atom LT Hoody and the Patagonia Nano-Air Jacket. Both are designed to provide warmth, breathability, and mobility, making them ideal for activities like hiking, climbing, and skiing. However, each has its strengths and weaknesses, making the choice between them a matter of personal preference and intended use.
In this detailed comparison, we’ll break down the key differences between these two jackets, covering aspects such as insulation, breathability, durability, fit, and overall performance.
1. Overview of the Arc'teryx Atom LT Hoody
The Arc'teryx Atom LT Hoody is a lightweight, insulated jacket designed for high-output activities in cold conditions. It features Coreloft™ synthetic insulation, which provides excellent warmth-to-weight ratio while maintaining breathability.
Key Features of the Atom LT Hoody:
Insulation: Coreloft™ synthetic insulation (60g/m²)
Shell Material: Tyono™ 20 denier nylon with DWR finish
Weight: ~13.2 oz (375g)
Fit: Trim fit with articulated patterning for mobility
Hood: Adjustable, insulated StormHood™
Breathability: Side fleece panels for enhanced ventilation
Best For: Layering in cold conditions, high-output activities
2. Overview of the Patagonia Nano-Air Jacket
The Patagonia Nano-Air Jacket is designed for those who need maximum breathability and stretch. It features FullRange® insulation, which allows for excellent air permeability while still providing warmth.
Key Features of the Nano-Air Jacket:
Insulation: FullRange® synthetic insulation (60g/m²)
Shell Material: 100% nylon ripstop with DWR finish
Weight: ~11.9 oz (338g)
Fit: Regular fit with mechanical stretch
Hood: Available in the hoody version
Breathability: High air permeability for active use
Best For: Stop-and-go activities, aerobic pursuits
3. Insulation & Warmth Comparison
Both jackets use synthetic insulation, but the Nano-Air’s FullRange® insulation is designed to be more breathable and stretchy, making it ideal for high-intensity activities. The Atom LT’s Coreloft™ insulation is slightly more efficient in trapping heat, making it a better option for colder conditions or static warmth.
Which One is Warmer?
Atom LT Hoody: Warmer due to its better heat retention.
Nano-Air Jacket: Slightly less warm but more breathable.
4. Breathability & Ventilation
Breathability is where the Nano-Air Jacket truly shines. Its FullRange® insulation allows air to move freely, preventing overheating during intense activities. The Atom LT Hoody, on the other hand, has fleece side panels that help with ventilation but do not match the Nano-Air’s breathability.
Best for Breathability:
Nano-Air Jacket: Superior breathability for high-output activities.
Atom LT Hoody: Moderate breathability, better for layering in cold conditions.
5. Durability & Weather Resistance
Both jackets feature DWR-treated shells, making them water-resistant but not fully waterproof. The Atom LT Hoody’s Tyono™ 20 denier nylon is slightly more durable than the Nano-Air’s softer nylon shell, which is more prone to wear and tear.
Best for Durability & Weather Resistance:
Atom LT Hoody: More durable and better wind resistance.
Nano-Air Jacket: Softer fabric, less wind-resistant.
6. Fit & Comfort
The Nano-Air Jacket has a more relaxed fit with added stretch, making it extremely comfortable for dynamic movements. The Atom LT Hoody has a trim fit, which is better for layering but may feel slightly restrictive compared to the Nano-Air.
Best for Comfort & Fit:
Nano-Air Jacket: More stretchy and comfortable.
Atom LT Hoody: More form-fitting for layering.
7. Weight & Packability
Both jackets are lightweight, but the Nano-Air Jacket is slightly lighter at 11.9 oz, compared to the Atom LT Hoody’s 13.2 oz. However, the Atom LT is more packable, making it a better choice for backpacking or situations where space is limited.
Best for Packability:
Atom LT Hoody: More compressible and packs smaller.
Nano-Air Jacket: Slightly bulkier due to stretch fabric.
8. Price & Value
Both jackets are premium options, with prices typically ranging between US$200-$300. The Nano-Air Jacket tends to be slightly more expensive, but it offers better breathability and comfort. The Atom LT Hoody provides better warmth and durability, making it a better long-term investment for cold-weather layering.
Best for Value:
Atom LT Hoody: Better durability and warmth for the price.
Nano-Air Jacket: More breathable and comfortable, but pricier.
9. Final Verdict: Which One Should You Buy?
Choose the Arc'teryx Atom LT Hoody if:
✅ You need a warmer jacket for cold conditions.✅ You want better durability and wind resistance.✅ You prefer a trim fit for layering.✅ You need a more packable jacket for travel.
Choose the Patagonia Nano-Air Jacket if:
✅ You need maximum breathability for high-intensity activities.✅ You want a softer, stretchier, and more comfortable fit.✅ You are doing stop-and-go activities where breathability is key.✅ You prefer a more relaxed fit for mobility.
Frequently Asked Questions (FAQ)
