The Stratus Jacket uses plant-based Sustans® insulation that has performance similarities to both traditional down and synthetic wadding, creating a ‘best-of-both-worlds’ material.
The Stratus Jacket is packed full of benefits thanks to its innovative insulation. It’s incredibly warm, water-resistant, wind-resistant and machine washable, plus it looks and feels fantastic.
Like regular synthetic insulation, Sustans® fibres have a superior elasticity that achieves great recovery, flexibility and warmth retention whilst also being fully machine washable and quick drying – a perk that can’t be achieved in most natural downs due to its high moisture absorption. But, unlike wadded synthetic insulation, it mimics the look and feel of real down by manufacturing the fibres into fill-like clusters rather than sheets of wadding, creating a softer finish with a better drape.
