Originally built for mountaineering, the FalketindWarm1Active excels at ski touring, trail running, and brisk hikes – keeping you dry, comfortable, and perfectly temperature-regulated.
What Is the Norrona Women's Falketind Warm1 Active Jacket?
The Falketind Warm1 Active Jacket is a lightweight, performance-oriented midlayer built for versatility and dynamic movement. Weighing just 192g (size M), it provides maximum breathability and rapid moisture management, keeping you comfortable even during high-output adventures.
Originally designed for mountaineering, this jacket's refined balance of warmth, stretch, and airflow makes it just as suitable for ski touring, trail running, hiking, or general outdoor use. Whether worn as a standalone layer on milder days or under a shell in colder conditions, it ensures consistent thermoregulation without bulk.
What Is It Made Of?
Main Fabric
The main fabric features Norrona's lightweight warm1 fleece, made entirely from 100% recycled polyester (PES). This soft, lofty material provides impressive insulation for its low weight, trapping warm air close to the body while efficiently wicking away moisture.
It dries quickly after exertion or washing, and its smooth outer surface offers excellent durability for long-term use under a shell or harness.
Secondary Fabric
Strategically placed grid fleece panels improve mobility, stretch, and breathability in key areas. This fabric features a smooth, knitted exterior and a one-sided grid interior that enhances airflow, allowing heat to escape during high-intensity movement while maintaining core warmth.
The added elastane provides flexibility and comfort, ensuring unrestricted motion across all activities.
About warm1 Fabric
The warm1 series represents Norrona's lightest and most breathable fleece category, weighing under 200g/m². These fabrics trap warm air effectively while maintaining high moisture transport for all-day comfort.
When worn alone, they allow ample air circulation to prevent overheating in mild conditions. Layered under a shell, they provide efficient insulation and superior temperature regulation — making them among the most versatile and high-performing fleeces available.
Responsible Construction
Both fleece fabrics used in the Falketind Warm1 Active Jacket are Bluesign and Global Recycled Standard (GRS) certified, ensuring they meet some of the world's strictest sustainability and safety standards.
The Bluesign certification guarantees that no harmful substances are used during production, while also ensuring that emissions and waste are reduced through efficient resource management. Meanwhile, GRS certification confirms the recycled origin of the fibres and validates that the recycling process meets rigorous environmental and social criteria.
HeiQ Fresh FFL Odour-Control Technology
To further enhance comfort and practicality, the Falketind Warm1 Active Jacket is treated with HeiQ Fresh FFL. This innovative, bio-based odour-control finish helps prevent unpleasant smells caused by bacteria and sweat.
Unlike traditional chemical or silver-based treatments, HeiQ Fresh FFL uses renewable, non-toxic ingredients derived from natural sources, making it safer for both the wearer and the environment.
This treatment keeps the fleece fresh for extended periods, making it ideal for multi-day trips, alpine adventures, or consecutive training sessions without the need for washing, while maintaining softness, breathability, and moisture management.
What Are Its Features?
Fit and Weight
The Falketind Warm1 Active Jacket has a regular fit that layers easily under shells or over baselayers. At only 192g (size M), it delivers the warmth and protection of a traditional fleece at a fraction of the weight.
Comfortable, Chafe-Free Collar
The soft, low-profile collar sits comfortably against the neck without irritation, providing warmth and protection without adding bulk.
Front Zip with Chin Guard
A smooth full-length front zip allows for easy temperature regulation, while the integrated chin guard prevents rubbing or discomfort during extended wear.
Zippered Chest Pocket
A secure chest pocket provides convenient access to small essentials such as a phone, GPS, or energy bar, making it ideal for use under a harness or backpack.
Floating Mid-Mounted Pockets
The jacket includes two mid-mounted hand pockets that remain accessible while wearing a climbing harness or hip belt. Their floating construction reduces bulk and enhances comfort around the waist.
Stretch Side Panels
Flexible stretch panels at the sides improve mobility and ventilation, reducing bulk while maintaining a trim, ergonomic fit for layering.
Gusseted Underarms and Articulated Sleeves
The gusseted underarm design and articulated sleeves allow full freedom of movement without the fabric bunching or lifting — ideal for climbing or ski touring.
Elastic Cuffs with Thumb Grips
Elastic cuffs with integrated thumb loops keep sleeves securely in place, providing additional coverage and warmth for the hands during cold or windy conditions.
Elastic Hem and Dropped Back
The elasticated hem helps seal in warmth while maintaining a clean, fitted look. A longer back cut provides extra coverage and helps prevent heat loss when reaching or bending.

Norrona Falketind Warm1 Active Jacket Review We’re big fans of how Norrona nail technical layering, and the FalketindWarm1Active is a standout example. It’s one of those rare fleeces that genuinely balances warmth and cooling – no overheating, no clammy feel, just smooth temperature regulation as your effort changes. Built for movement and fast-paced days, it dries quickly, feels premium next to the skin, and delivers dependable performance whether you’re pushing uphill or cruising along ridgelines.
What’s the Fit Like? The FalketindWarm1Active features a regular, ergonomic fit tuned for active use. Lightweight fleece combined with stretch grid panels allows unrestricted movement when climbing, skinning, or hiking at pace. Articulated sleeves and gusseted underarms prevent lift or bunching, while mid-mounted pockets sit neatly above a harness or pack belt. Subtle details like elastic cuffs with thumb loops and a dropped back hem help seal in warmth and keep everything perfectly in place as you move.
Is It Warm Enough for Winter? Despite weighing just 252grams, the FalketindWarm1Active punches well above its weight. It works brilliantly as a standalone layer in mild spring or autumn conditions and slots easily under a shell when temperatures drop. The soft fleece traps warmth close to the body while maintaining airflow – the ideal balance between insulation and breathability. In winter, it’s a go-to active midlayer; in summer, a lightweight jacket for breezy mornings or alpine ridgelines.
