Founded in 1975, this Swedish purveyor of refined, "understated Nordicness" is enjoying a new wave of popularity (thanks to support from the likes of @organiclab.zip) and rightfully so - it's really good.
Competitors offer similar tote bags with stowaway backpack straps, but Klättermusen is the brand to back in my opinion.
Their committment to responsible material research and unique design detailing makes it an easy winner for an outdoor/urban crossover option.
