What is the Norrona Men's Falketind Thermo40 Hood Jacket?
The Norrona Falketind Thermo40 is a lightweight, synthetic, insulated jacket designed for year-round mountaineering. Whether heading out for ski tours, hiking, or general outdoor activities, this jacket will keep you warm and comfortable.
What is it made of?
The jacket's outer fabric is aeroDownproof- a 20-denier (20D) ripstop recycled nylon with PFC-free DWR treatment.
This outer fabric balances lightweight design with durability. Ripstop construction weaves stronger reinforcement threads into the fabric, reducing the risk of rips or abrasions, which can occur when brushing against sharp rocks or branches during outdoor activities. This structure ensures the jacket can withstand rugged environments.
The fabric also blocks wind to keep you warm. Its breathable construction is crucial during high-intensity activities, like hiking or skiing, where you must release excess heat and moisture to avoid overheating.
The fabric is treated with a PFC-free Durable Water Repellent (DWR) coating. PFCs (perfluorocarbons) are chemicals commonly used in water-repellent treatments but are harmful to the environment. By using a PFC-free DWR, Norrona ensures that the jacket provides excellent water repellency and is more environmentally friendly. This treatment helps water bead up and roll off the fabric, keeping you dry in light rain and snowy conditions.
On the inside, the jacket has thermo40 synthetic insulation made entirely from 100% recycled polyester. This insulation is designed to offer an excellent warmth-to-weight ratio, which means it keeps you toasty without adding much bulk or weight to the jacket.
One of the key advantages of thermo40 is its ability to retain warmth even when wet. Unlike down, which loses its insulating properties when saturated, synthetic fibres continue to trap heat, making this jacket ideal for damp or unpredictable mountain environments.
Bluesign certification of the fabric adds an environmental and social responsibility layer. This certification means that every step of the textile manufacturing process has been vetted to eliminate harmful substances, reduce water and air pollution, and ensure worker safety. Bluesign not only provides a safer product for the consumer but contributes to a more sustainable and eco-conscious textile industry.
What are its features?
This jacket has a helmet-compatible hood designed to fit under your helmet. With convenient one-handed adjustments, it stays securely in place, keeping you protected and helping you stay focused on your outdoor pursuits.
For storage, the jacket features a zippered chest pocket and two hand-warming pockets. These provide convenient options for carrying small essentials like keys, a phone, or a trail map. The hand-warming pockets are also great for keeping your fingers warm during cold-weather outings, offering both functionality and comfort.
The jacket also comes with elastic cuffs designed to seal in warmth by fitting snugly around your wrists. This feature prevents cold air from entering and trapping body heat, handy in windy or cold environments. The jacket's insulation ensures that the generated warmth stays inside while keeping drafts and moisture out.
In addition to the cuffs, the jacket's technical fit, complete with articulated arms, provides great freedom of movement. The articulated design means that the arms are cut and shaped to follow your body's natural movement, which is beneficial during activities that require a wide range of motion, such as skiing, hiking, or reaching overhead.
The jacket's extended back, also known as a drop-tail hem, provides additional coverage and protection, particularly when bending over, sitting down, or engaging in activities like skiing or snowshoeing. This extra length helps shield your lower back and hips from cold drafts, wind, and moisture, common in winter environments. It's beneficial when sitting on cold, wet surfaces or leaning forward, as it prevents exposure that can quickly lead to discomfort. The added coverage contributes to overall warmth and protection, making the jacket more versatile for various activities.

How warm is the Falketind Thermo40, and what temperatures is it suitable for? The Thermo40 packs 40g/m² of synthetic insulation, which hits that sweet spot between warmth and packability. It's not your big belay puffy for freezing standstill moments, but it's an absolute gem when it comes to a versatile midlayer. People love it as their go-to piece for ski touring, cold-weather hikes, chilly bike rides—and it shines just as much for casual wear or travel, too. Lightweight, comfy, and low-bulk, it's easy to stuff in your pack and forget about until you need it. It works great as a light outer layer in milder weather or slots under a shell when temps drop—think around -5°C to -10°C, as long as you're layering smartly. It blocks light wind, though heavy gusts will cut through—so if you're heading into rougher weather, pair it with a Gore-Tex shell.
How the Norrøna Falketind Thermo40 Hood Jacket fits? It has a technical cut built for movement, with enough room to comfortably layer underneath without feeling bulky. Most people find it fits true to size, with a slightly slim profile—especially in the torso and arms. The articulated sleeves and longer back hem are great touches for reaching, stretching, or wearing a harness. If you're familiar with Arc'teryx sizing, it's comparable, though Norrøna tends to run trimmer. If you're in between sizes or want extra space for thicker layers, sizing up might be worth considering. Overall, it's a well-balanced, movement-friendly fit that works great for everything from ski tours to trail hikes.
Why Not Pair It with Norrøna Falketind Flex1 Pants? If you're heading out for a full day of activity, pairing the Norrøna Falketind Thermo40 Hood Jacket with the Falketind Flex1 Pants is a solid move. The Thermo40 gives you just the right amount of synthetic insulation—warm enough for cooler conditions but light and low-profile so it won't get in your way. The Flex1 Pants are breathable and stretchy, with enough wind resistance and water repellency to handle fast-paced hikes, mountaineering, or ski touring. Together, they balance comfort, mobility, and protection so you can move freely and stay comfortable as conditions shift. Buy Falketind Flex1 Pants FAQ
How does the Norrøna Falketind Thermo40 Hood Jacket perform in wet conditions?
Thanks to its synthetic Thermo40 insulation, the jacket retains warmth even when damp. The outer fabric is treated with a PFC-free durable water repellent (DWR) finish, offering resistance against light rain and snow. However, for heavy downpours, pairing it with a waterproof shell is recommended.

Absolutely. Its breathable materials and lightweight design make it suitable for high-output activities such as ski touring, mountaineering, and trekking. The articulated arms and technical fit allow for a full range of motion.

Weighing approximately 274 grams (size M), the jacket is highly packable and can be compressed into a backpack without taking up much space.

Yes, its lightweight and comfortable design make it a great choice for casual outings and travel. It provides sufficient warmth for temperatures ranging from 10°C to 15°C, making it versatile for various settings beyond outdoor adventures.
Is the Norrøna Falketind Thermo40 Hood Jacket noisy when you move?
Nope, it's pretty quiet. The outer fabric has a soft, matte finish that doesn't rustle like some waterproof or windproof jackets do. That makes it a great choice for activities where you want to move quietly—like wildlife watching—or for everyday wear when you don't want to sound like you're wearing a crisp packet.
How easy is it to wash the Norrøna Falketind Thermo40 Hood Jacket?
Super easy. Since it's synthetic, you don't need to worry about clumping like you do with down jackets. Just chuck it in the wash on a gentle cycle, use a technical detergent (or a gentle one without fabric softeners), and hang it to dry. It dries pretty quickly and doesn't lose its shape.
Will the Norrøna Falketind Thermo40 Hood Jacket still be comfortable if I'm wearing a backpack?
Yes! The seams and pockets are placed thoughtfully so they don't interfere with a hipbelt or shoulder straps. The fabric's soft enough to avoid chafing, even on longer days out. And because it's so lightweight and breathable, it won't turn into a sweatbox under your pack.
