Softie® Insulation

Softie^® Insulation

Softie^® is a synthetic polyester insulation used in sleeping bags from the Softie^® product line. It’s designed to closely mimic the natural structure of organic fibers, delivering high thermal efficiency and excellent user comfort.

This insulation consists of ultra-fine polyester fibers that are randomly arranged during production – some remain straight, others are twisted or curled. This creates a structure that imitates animal fur, which is naturally optimized for warmth. As a result, Softie^® traps heat effectively and maintains warmth longer than traditional straight fiber fills.

Special bonding resins are used to hold the fibers together while preserving their softness and flexibility. Despite its advanced construction, Softie^® remains highly practical – it’s washable, dries quickly, and retains its insulation even when wet.
