Breathable Warmth for Every Adventure

 

For those who don’t slow down when the weather turns, the Marmot Aerothermal Collection delivers the next evolution of active warmth. Every PrimaLoft jacket and vest in the line features adaptable insulation that keeps pace from the first mile to the last climb. Whether you’re ski touring, hiking , or heading into town after a day outdoors, these lightweight insulated jackets provide dependable comfort and breathability that work as hard as you do.

 

Performance That Moves With You

 

At the heart of the Aerothermal Collection is PrimaLoft® Active Evolve insulation, engineered for skiers, hikers, and explorers who live in motion. This advanced material mimics the loft and softness of high-performance fleece while remaining ultralight and exceptionally breathable.

 

Key benefits of PrimaLoft® Active Evolve insulation:

 

• Adapts to activity level for warmth without overheating
• Sheds excess heat during climbs and traps warmth when you pause
• Provides soft, fleece-like comfort with low bulk

 

Each PrimaLoft jacket is constructed with a 100% recycled ripstop shell for lightweight durability and natural breathability, while elastic-bound hems and cuffs seal in warmth.The result? Lightweight insulated jackets that feel effortless in motion yet cozy at rest—ideal for unpredictable fall hikes, cold-weather runs, or brisk morning commutes.

 

Advanced WarmCube® Active Technology

 

Select styles in the Aerothermal lineup take warmth further with WarmCube® Active technology , Marmot’s signature thermoregulating innovation. These breathable jackets and vests use 3D cubes of 700-fill down suspended in air channels to:

 

• Prevent down shift and cold spots
• Create air pockets for dynamic heat retention
• Improve airflow and temperature regulation

 

This system works in sync with PrimaLoft® Active Evolve panels, combining instant comfort with enduring warmth. Additional features include:

 

• Durable Water Repellent (DWR) coating to block light precipitation
• Down Defender treatment to maintain warmth even in damp conditions

 

Whether you’re skinning uphill or resting at the summit, this combination keeps your body balanced—venting heat when you’re moving and insulating when you stop.

 

Everyday Versatility Meets Technical Performance

 

From the slopes to the city, the Aerothermal hoody, half-zip, and vest adapt to every setting. Thoughtful details make each piece ideal for layering or standalone wear:

 

• Zippered hand pockets and secure chest storage
• Minimalist styling that transitions easily between activities
• Lightweight construction that stows neatly in a pack

 

These PrimaLoft jackets are the ultimate “don’t leave home without it” layers—dependable, compact, and made for motion.
