The Mythic 400 is an exceptional choice for ultra-light mountain endeavours. Clocking in at just 660 grams yet offering solid three-season performance, its impressive stats are a result of premium materials and precision design combined. The thermal efficiency of the 900-fill hydrophobic down is enhanced through the trapezoidal baffles of the box wall construction, resulting in a warm yet light and compressible sleeping bag. When you need to cut weight without sacrificing comfort on your next mountain mission, be sure to choose the Mythic.

THREE Season
Three season sleeping bags are suitable for use from spring through to autumn. Comfortable and versatile, they offer the warmth needed for cooler temperatures down to and just below freezing.
Pertex Equilibrium
The unique structure of Pertex® Equilibrium created a comfortable microclimate by balancing weather protection and breathability. Pertex® Equilibrium uses a double weave construction in which a tightly woven outer face provides protection from the elements whilst a more openly woven inner face helps to move moisture away from your body.
Gradient structure helps to move moisture away from the user
Pertex® Shield fabrics provide lightweight waterproof protection whilst remaining highly breathable. Designed for intense mountain pursuits where weight and breathability are key, Pertex® Shield fabrics allow you to move fast and stay comfortable. The versatile 2, 2.5 and 3-layer constructions combine lightweight face fabrics with waterproof, windproof and breathable membranes. A durable water repellent (DWR) finish applied to the face fabric sheds rain and snow, which helps to maintain breathability.

Pertex® Quantum (formerly Pertex Classic, Mircolight, Quantum and Quantum GL)
Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft. Precisely constructed from incredibly fine yarns, Pertex® Quantum fabrics are designed to trap still air and improve the efficiency of insulation. A durable water repellent (DWR) finish sheds light rain and snow to provide additional weather protection.

Soft to the touch
Windproof to retain warmth
Pertex® Quantum Pro (formerly Pertex Endurance)
Pertex® Quantum Pro uses an ultra-thin water resistant coating to provide increased weather resistance for extreme conditions. By combining a tightly woven face fabric with a microporous coating, Pertex® Quantum Pro delivers a very high level of water resistance whilst remaining lightweight, soft and breathable. The increased weather resistance and durable construction means these fabrics are ideal for use in cold or damp environments where keeping warm and dry is crucial.

Durable construction
Maximises the thermal efficiency of insulation
Pertex® Quantum Air (formerly Pertex Mircolight)
Pertex® Quantum Air is engineered with increased air permeability to provide a balance between wind resistance and breathability. The more openly woven structure of Quantum Air fabrics allows airflow through the fabric, which helps to regulate your body heat and keep you comfortable for longer. This balance of air permeability and wind resistance means Pertex® Quantum Air fabrics are perfectly suited to intense mountain pursuits. A durable water repellent (DWR) finish sheds light rain and snow to provide additional weather protection.

Responsible Down Standard
The Responsible Down Standard (RDS) aims to ensure that down and feathers come from animals that have not been subjected to any unnecessary harm. It is an independent, voluntary global standard, which means that companies can choose to certify their products to the RDS, even if there is no legislation requiring them to do so. The RDS was developed and revised over three years, with the input of animal welfare groups, industry experts, brands, and retailers. The standard recognises and rewards the best practices in animal welfare. Find out more
