We evaluate materials based on how they perform across the entire life of a product, rather than judging them solely at the point of manufacture.
Technical synthetic fabrics can carry a greater environmental cost during production, but their exceptional resistance to abrasion, water and wear can allow a product to remain in service for considerably longer.
For us, the question isn't simply which material has the lowest impact when it leaves the mill. It's whether that material allows us to make a product that lasts, performs and can ultimately avoid being replaced.
We'd rather make one pack that remains in use for decades than several that need replacing over the same period.
