9. SANDQVIST MARTA GYM BAG

Forget duffle or drawstring, this lightweight backpack – made from recycled nylon – is aesthetically sharp and prioritises function. There’s a front slip pocket for your yoga mat and an internal compartment for your laptop. When it’s been well-loved, you can return it for a repair to extend its life, or hand it in for recycling in exchange for a voucher giving you 20% off your next bag. Truly built to last. £165, sandqvist.com
