How Warm is the Arc’teryx Atom AR: A Comprehensive Guide
When it comes to choosing the right jacket for cold weather activities, the Arc’teryx Atom AR is often at the top of the list. But how warm is it, really? In this detailed guide, we’ll explore the warmth of the Atom AR from multiple dimensions to help you make an informed decision.
Understanding the Atom AR
The Arc’teryx Atom AR is a versatile, lightweight, and breathable jacket designed for a wide range of activities, from hiking to climbing. It features a GORE-TEX Pro membrane, which is known for its excellent waterproof and breathable properties. The jacket also has a trim fit, making it ideal for layering under a shell or worn alone on warmer days.
Insulation and Warmth
One of the key factors that determine the warmth of a jacket is its insulation. The Atom AR uses Arc’teryx’s proprietary synthetic insulation, known as Arc’teryx Coreloft. This insulation is designed to provide warmth without adding excess weight or bulk. Here’s a breakdown of the insulation and warmth of the Atom AR:
| Insulation Type | Weight | Warmth Rating |
|---|---|---|
| Coreloft | Lightweight | Warm |
While the Atom AR is designed to be warm, it’s important to note that it’s not as warm as a jacket with down insulation. However, the Coreloft insulation provides excellent warmth-to-weight ratio, making it a great choice for those who want a balance between warmth and packability.
Layering with the Atom AR
One of the advantages of the Atom AR is its ability to be used as a mid-layer or a standalone jacket. When used as a mid-layer, it can be worn under a shell jacket to provide additional warmth and insulation. Here’s how you can layer with the Atom AR:
-
Base Layer: Wear a moisture-wicking base layer to keep sweat away from your skin.
-
Mid-Layer: Put on the Atom AR as a mid-layer to provide additional warmth.
-
Shell Jacket: If the weather gets colder or windier, add a shell jacket over the Atom AR for extra protection.
When worn as a standalone jacket, the Atom AR is suitable for temperatures ranging from 30掳F to 50掳F (0掳C to 10掳C). However, the actual warmth can vary depending on your activity level, the weather conditions, and the layers you wear underneath.
Waterproofing and Breathability
The Atom AR is designed with a GORE-TEX Pro membrane, which ensures excellent waterproofing and breathability. This means that you can stay dry and comfortable even when you’re active in wet conditions. Here are some key points about the waterproofing and breathability of the Atom AR:
-
Waterproof Rating: 20,000 mm
-
Breathability: 20,000 g/m虏/24h
The jacket also features a DWR (durable water repellent) finish, which helps to repel water and prevent it from soaking into the fabric. Additionally, the Atom AR has pit zips for increased breathability, allowing you to release excess heat and moisture when you’re working hard.
Fit and Comfort
The Atom AR has a trim fit, which is designed to fit close to the body without restricting movement. This makes it an excellent choice for activities that require a lot of mobility, such as climbing or hiking. The jacket also features a helmet-compatible hood, underarm ventilation zips, and a drop hem for added comfort and functionality.
Conclusion
When it comes to warmth, the Arc’teryx Atom AR is a versatile and reliable choice for cold weather activities. While it may not be as warm as a jacket with down insulation, its synthetic Coreloft insulation provides excellent warmth-to-weight ratio. When layered properly, the Atom AR can keep you warm in temperatures ranging from 30掳F to 50掳F (0掳C to 10掳C). With its waterproofing, breathability, and comfortable fit, the Atom AR is a great investment for anyone looking for a high
