Mammut says:
The perfect all-rounder, this insulated jacket combines exceptional warmth with lightweight packability to keep up with all your mountain pursuits. Wind and abrasion resistant, its durable water repellent (DWR) coating protects you from light showers, while zoned insulation ensures optimal thermal protection without restricting movement. Featuring an adjustable hood and three zippered pockets, it’s a practical and versatile choice for exploring the great outdoors.
Our Verdict
The Mammut Rime IN Flex Hooded Jacket is a versatile and lightweight mid-layer designed to keep you warm without compromising mobility or breathability. Its blend of thoughtful features and performance materials makes it well-suited to a variety of mountain activities.
Weighing 454g in a medium, the jacket feels exceptionally lightweight but still provides robust protection. The zoned insulation – 80g/m² on the body and 60g/m² on the arms and hood – strikes a good balance between warmth and flexibility, keeping you cosy without feeling bulky. The Pertex Quantum Air fabric enhances breathability while offering wind and water resistance, and its PFC-free DWR treatment handles light showers effectively.
Practical details include a well-fitted, adjustable hood, two backpack-compatible zip pockets, and an elasticated hem and cuffs that prevent heat loss. Its ability to pack into its own pocket is particularly handy for those looking to minimise bulk. While it’s not intended for extreme conditions, this jacket shines as an all-rounder for milder climates or high-output adventures.
