15 Sustainable Sweatpants And Sweatshirts For Your Loungewear Wardrobe
Matching Sets To Sweat (Or Snuggle) In
We’ve said farewell to our workwear and a long hellooo to the loungewear trend, especially as the days grow shorter and the weather gets cooler. So it’s no surprise that we’ve got our eyes on snuggly sweatshirts and sweatpants for ourselves and our loved ones this holiday season. (Because who wouldn’t want to be MORE cozy and comfortable?)
These brands combine style and comfort with sustainable fabrics and ethical production practices. Many use organic, recycled, or responsibly sourced materials, and some offer inclusive sizing and collections for all genders and ages. That means you can wrap up your parents, partners, and loved ones in quality sweats that make for less eco-impact and more lounging.
