Ravnø Dynatec Pro Altitude Jacket | Lupus
Ravnø Dynatec Lupus Pro Altitude Jacket® – a 3-layer shell jacket – provides protection even on the harshest weather days. The jacket features two chest pockets for a hunting radio, with a dedicated inner pocket for stabilizing the radio, mobile phone, or GPS. Both pockets have separate openings for antennas and an internal cable outlet for earplugs. The left chest pocket has its own entry from the inside of the jacket. Two spacious front pockets are also available.
Full ventilation on each side allows for airflow during transport stages. Hidden adjustments in the hood, neck, and waist provide a secure fit. Adjustable cuffs and an extra-long back ensure proper drainage during heavy rain. The material is rustle-free to minimize noise. YKK Vision 8 zippers and a membrane composed of Dynatec®, C-Change®, and NanoSphere® technologies developed by Schöeller Elite Textiles in Switzerland.
The jacket can be washed at 40 degrees with natural soap, without fabric softener. Light ironing after washing helps maintain the performance of the membrane.

Note on “breathable membranes”: Membranes are porous membranes. In order for moisture to move from one side to the other side of the jacket, it needs to be porous. The textile industry lacks a standardized measurement for Moisture Vapor Transmission Rate (MVTR), creating challenges and often confusion with terms like “highly breathable” or “extremely breathable.” The main challenge lies not necessarily in the membrane’s ability to transfer liquid from one side to the other but in the percentage of humidity on the inside of the jacket compared to the outside. If the humidity is nearly the same on both sides of the membrane (both against the body and in the air), the experience of the membrane’s breathability may be neutralized. It still transfers moisture from one side to the other, but the perception is affected by the amount of humidity. In practice, it is still important to ventilate, even when it rains, during high-intensity activities when sweating. When engaging in high-intensity activities in heavy rain, it is advisable to ventilate under the armpits to reduce humidity close to the body.
Breathable membranes have their limitations. While they are beneficial under certain conditions, after many years in the field, one learns to switch between wool, membranes, and cotton. Cotton is fantastic if it doesn’t rain too hard. A wool sweater or an appropriate mid-layer is best to wear under a membrane during heavy rain. This means not only wool underwear but also a thin wool sweater/mid-layer jacket. It functions as a moisture storage space, retains heat, and easily releases moisture when there is an opportunity to ventilate the jacket.
For most of us who hunt in Norway, membranes are predominantly used as rain jackets. This is understandable but can often create high expectations regarding the textile’s performance capabilities. At Ravnø, we, as testers, are as diverse as anyone else. For example, I, as the writer, am a “sweaty type.” I sweat heavily during intense activities. Others sweat less. For me, cotton often works better, assuming it’s not pouring rain. If it’s raining heavily, I need to reduce my activity level and put on an Altitude jacket. On the other hand, some of the other guys sweat less and can maintain high activity levels in a shell jacket, both in the heat and in the rain.
The best approach is to listen to your own body. What have you experienced before? How does your body react to different activity levels? Based on previous experiences, choose a jacket that best suits the way your body responds to high activity.
Good luck – Ravnø
