Given that Lefrik always keeps the environment in mind, you can expect to find a plethora of sustainable materials defining each of its creations. That's certainly the case for this rucksack given that it's stitched together from recycled polyester sourced from PET bottles doused in a waterproof coating. About LefrikEstablished almost a decade ago, Lefrik is a label dedicated to crafting a range of accessories entirely from eco-friendly, recycled materials. Impressed? We thought you might be. Made to answer the issues faced by modern-day commuters and the " digital nomad" , each product is designed in Spain, made in Asia, oh, and is fully vegan, too. Nice.
