The North Face’s Thermoball technology has been a winner for a few years now. On top of jackets, a personal favourite is the thermoball mules, which, with the approach of colder days, will see a very welcomed reintroduction into everyday rotation.
The premise behind Thermoball tech is that down fill – the current go to for insulation – is unethical. Yeah, TNF uses down fill, and yeah, they’ve got an RDS for maximum supply chain transparency, but ultimately, exploring alternatives is absolutely necessary. Enter: Thermoball.
Thermoball is a polyester alternative to down made by TNF and PrimaLoft, and each year it sees some new fine-tuning. This year, the updated Thermoball Eco is made entirely from recycled materials, and the new stitching design increases insulation capacity. One advantage of Thermoball over traditional down is that it’s fast drying. Down, typically, is not. I once fell in a river wearing a TNF Nuptse. It was a long and very cold walk home.
