ASKET makes one sweatpant. That’s all. There are no seasonal drops, no trend cycles — just one, timeless style refined over time and built to last. Cut from 380gsm organic loopback unbleached cotton and milled, cut, and sewn entirely in Portugal, these are the kind of sweatpants you buy once and keep for years.
What makes ASKET different is the great transparency: they publish a breakdown of the full costs, CO2 emissions, water consumption, and energy consumption of the entire garment – right on the product page.

They also take back any unwanted ASKET clothing for resale, closing the loop on the product’s life.

We hope you found the right pants!
There are many ways to be fashionable, and some are easier than others. Some methods are also more important to you than others, and some companies will use subtle but subtle gestures to jump on the bandwagon and distract customers from shady and damaging practices.
As customers become more aware of the fashion industry’s impact on the environment and the lives of those involved in production, it is important that companies fall in line and maintain a high standard. Hopefully, this list of the right pants will give you some good clues into the world of sustainable fashion and help you make informed fashion choices.
