Synthetic Insulation Explained
Synthetic insulation explained.
Synthetic insulation is completely man-made. It is usually created from polyester to form either sheets of wadding or lofted (blown) structures that behave very similarly to down. Different sized filaments are intertwined with each other to create air pockets that insulate you from the cold.
What’s so great about synthetic insulation?
Synthetic insulation is strong, lightweight, and resilient. It’s ideal for environments that are cold and wet, as it’s fast-drying and remains effective in damp conditions. There are three types of synthetic insulation, each with its own unique benefits.
Otherwise known as ‘blown’ insulation, loose fill allows you to create baffled synthetic insulation that looks, feels, and performs like down, but in a more weather-resistant package. Unlike sheet insulation, it mimics the appearance of down by lofting and trapping air within its fibres, making it great at boosting warmth.
This woven sheet insulation contains a structure of microfibres that traps heat and reflects it back to you. It provides reliable insulation in situations where you’ll be static, such as exposed belays. Protective and versatile, it withstands compression well and remains warm even when wet.
Active sheet insulation is especially well adapted to stop-start activities or fast-moving ascents, as it can be teamed with highly breathable fabrics. It’s designed to respond to your output, insulating or breathing to regulate your temperature across a wide range of conditions.
