Chili Philly Silly Season


They have become as ubiquitous with Christmas as candy canes: brightly coloured and boldly decorated, the festive sweater is ingrained in 21st century gift-giving tradition.

But for all their fun, did you know that the majority of holiday sweaters are made from acrylic and polyester? Deriving from petroleum, these man-made fibres are not only coarse on the skin but are the equivalent of wearing plastic shopping bags, not only making them prone to overheating but hugely impactful on the planet, too. In the U.K. alone, it is estimated that we will spend more than £220 million on novelty Christmas sweaters this year. But a jumper is not just for Christmas, and more than a quarter are discarded after just one wear, with charity shops inundated with tens of thousands more. And that’s before the synthetic microfibres find their way to the waterways, where they will disturb the order of natural marine life.

The natural crimp of wool traps pockets of air, insulating your skin from the cold.

By contrast, wool offers a brilliant alternative, and the best jumpers are those made from Merino wool, a natural, renewable and biodegradable fibre. Did you know that wool can absorb ten times as much moisture vapour as polyester? And that’s not all. The natural crimp of wool traps pockets of air, insulating your skin from the cold. 1kg of dry wool can release the heat equivalent to an electric blanket running for 8 hours. That’s really, really warm. And given that wool is the most re-used and recycled of all the common apparel fibres in the world, through a responsible choice of what we wear we can ultimately contribute to the long-term health of the planet.
