Atom Long Women's is a breathable insulation insulated jacket designed for trail hiking, built as a long-length layer that provides synthetic warmth in cold, changeable mountain conditions.
Versatile synthetic insulated mid layers with a high degree of weather resistance.
Man-made insulation with quick dry times, durability and retains warmth when damp.
Pair it with a women’s shell jacket and a beanie for cold, windy hikes.
Designed for hikers, our iconic Atom Jacket has also been a longtime favourite of climbers, skiers, and snowboarders for breathable warmth in all kinds of mountain conditions. This long version gives you the same reliable Coreloft insulation (warmer through the body and lighter under the arms) that won't pack out or lose heat when it's wet—in a bum-covering length. It stands alone for a low-output day hike, slides easily under our long Beta shell for a clutch layering system that'll keep out any storm.
What's been updated: Updated with additional recycled Coreloft™ insulation (from 60gsm to 80gsm) for more warmth, an added 2” of length for ease of layering with a hardshell, and a looser fit (including adding 4cm to the hip) to improve mobility.
Note: If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Note: Calculate your own body measurements, then select your product size.
1. Sleeve: With arm relaxed at your side and slightly bent, measure from center back neck, across shoulder to elbow and down to wrist.
2. Bust: With arms relaxed at your sides, measure under your arms, around the fullest part of your bust
3. Waist: Measure around your waist at the narrowest part.
4. Hip: Standing with feet hip width apart, measure around your hips at the widest part.
Cut snug to the body through the entire garment to enhance moisture management and thermal efficiency.
Cut slim to the body through chest, waist, hip and thigh for a low profile fit.
Cut comfortably from the body through bust/chest, waist, hip and thigh for a classic fit.
Cut loosely through the waist, hip, and thigh for a casual fit.
Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
