CLIMAAIR LIGHT: Lightweight, Breathable Warmth for Active Comfort

CLIMAAIR LIGHT - A versatile new material for year-round use.
Wear it on its own during high-output activities, or layer it under a shell when extra warmth is needed. With exceptional breathability and balanced insulation, CLIMAAIR LIGHT helps maintain a comfortable climate inside your clothing. It packs down compactly, offers excellent portability, and is the kind of layer you'll want to carry on every outing. From low-elevation hikes in fall through spring to summer alpine routes, it performs reliably across a wide range of seasons and outdoor pursuits.

Features of CLIMAAIR LIGHT

An illustration showing the fabric structure of CLIMAAIR Light. An explanation follows below.
The fabric's wide, open-knit structure provides outstanding lightness and breathability. Even during high-output activity, excellent moisture-wicking performance draws sweat away from the skin and disperses it quickly, helping reduce stuffiness inside your layering system. Long-pile polyester fibers trap air to provide a moderate level of warmth.

Easy temperature regulation with an outer layer

During activity


Among Montbell's fleece lineup, CLIMAAIR LIGHT offers the highest level of breathability. It allows air to pass through as you move, while quickly wicking and dispersing sweat to prevent moisture from building up inside your clothing. The result is lasting comfort while you stay active on the trail.
Shown here is an example of how the item is worn: layered under outerwear, with a backpack, and paired with the CLIMAAIR Light T-shirt.

In chilly conditions


When your body temperature drops and you begin to feel cold, such as while walking along a windy ridgeline or taking a break, simply add an outer layer to help retain warmth.
Shown here is an example of how it is worn: layered under an unzipped outer jacket, with a backpack and a CLIMAAIR Light T-shirt.

When body temperature rises


Even when your activity level is high and your body temperature rises, airflow quickly releases moisture and excess heat. You can regulate temperature without removing your mid layer, allowing you to keep it on comfortably throughout your activity.

Exceptionally lightweight and compact

The lightest fleece layer in Montbell's lineup, this T-shirt-style piece weighs just 3.9 oz (110 g), making it lighter than a Wickron short-sleeve T-shirt. It folds down compactly for excellent portability, challenging the idea that fleece has to be bulky.
