Why you will like it
- Aerogel has the highest insulation-to-weight ratio known to man.
- An innovative combination of Aerogel insulation and merino-wool fleece.
- Will retain its amazing insulating capability even when compressed.
The Guide Aerogel Hybrid Concept is an obvious contender to our ‘team favorite’ title. Combining silica Aerogel insulation panels and a new DWR-treated ultralight shell fabric with strategic merino wool fleece panels, it provides a unique combination of weather protection, breathable comfort, lightweight insulation and freedom of movement.

It is lightweight, comfortable, breathable and versatile — but above all it comes with unexpected insulation capabilities: The Aerogel panels will keep you surprisingly warm on colder days while staying peculiarly cool-ish during harder work. The material also has the unique ability to retain its amazing insulation capabilities even when compressed by a backpack carrying system or a rope.

The merino wool fabric has a complex double-knit structure, keeping the merino to one side of the fabric only, reaching 40% wool content where it matters. It is soft, warm and stretchable, effectively transporting moisture away from your body.

The Guide Aerogel Hybrid 2.0 Concept has been upgraded with our new ultralight rip-stop shell fabric that is wind resistant, water-resistant, stretchable and very breathable, and it is now offered in our signature Guide System™ colors.

It has an athletic fit that provides excellent freedom of movement. Use it as a mid-layer during winter for ski-touring or alpinism, or as a stand-alone garment for low-pulse activities like climbing or hiking in the summertime.

The Guide Aerogel Hybrid 2.0 Concept is a fundamental part of The Guide System™, our selective ecosystem of ultra-high-end technical layering products for professional use in extreme conditions.
