Let's start with the basics. Having a good suitcase or travel bag is essential when packing sustainably. We always recommend buying secondhand or borrowing items, but if that's not possible there are some great options on the market.
Investing in something high-quality will reduce the need for replacing cheaply made pieces and save resources. Premium travel gear brand NORTVI, for example, makes carry-ons and weekend bags with the extremely strong and eco-friendly material polycarbonate and 100% recycled PET bottles.
