The Dyna Action Parka is the perfect compromise between performance and packability for those venturing into variable winter conditions. It is a streamlined, technical layer for those who don’t compromise in winter conditions.
Montbell says:
Waterproof, highly breathable SUPER DRY-TEC delivers protection from rain and snow and vents moisture in a stretchy form. Two types of face fabrics are purposefully combined to achieve supple comfort at a light weight. Features a versatile design for everything from winter mountaineering and ice climbing, to hiking in snow-free conditions.

Our Verdict
The Montbell Dyna Action Parka feels like a refined mountain shell for fast-paced missions. Highly breathable and storm-ready, this shell strikes a balance between mobility and protection. At 400g (Medium), it delivers dependable waterproofing (20,000 mm) and outstanding breathability (60,000 g/m²/24 hrs), with stretch fabrics that don’t feel stiff or noisy.
What stands out is the hybrid construction: a more durable fabric is used across the shoulders and arms, while lighter 15-denier panels are used under the arms and across the back for improved airflow. The hood fits cleanly over a helmet, and the articulated sleeves and high collar add to its alpine-ready feel.
The pit vents and internal waist adjustment are well thought out, making it suitable for ski mountaineering, cold-weather trekking, or wet alpine scrambles where pace and protection are both key.
