Current synthetic insulation pieces may provide warmth, even when wet, and be extremely easy to pack down, but do not exactly breathe well when used in high activity situations. Some brands have tried to address this problem with hybrid pieces, where breathable fabrics replace insulation in places you tend to sweat the most. Polartec has decided to take a different approach, instead reinventing synthetic insulation altogether to create a warm, stable, air permeable layer that can be combined with more breathable fabrics.
