Why Are Down So Expensive Now?

The story behind skyrocketing down prices is a complex mix of supply chain issues and increasing demand. Traditional down, harvested from geese and ducks, has seen unprecedented price increases due to reduced farming activities and stricter animal welfare regulations. Manufacturers face challenges with unstable supply chains, while consumers struggle with jackets that now cost nearly double what they did just a few years ago.

What’s the Clo Value

Before diving into alternatives, let’s talk about something you might have seen on product labels – Clo value. Think of Clo as the “miles per gallon” rating but for warmth. One Clo equals the insulation needed to keep a resting person comfortable at 21\u00b0C (70\u00b0F). A typical winter coat ranges from 2.5 to 3 Clo, which makes the new aerogel fiber’s 3.27 Clo value particularly impressive.

Laboratory Results: Numbers That Matter

Understanding thermal performance isn’t just about feeling warm – it’s about measurable, scientific data. We’ve compiled comprehensive test results from two independent laboratory studies that demonstrate the exceptional performance of aerogel fiber fill.
