Men’s linen trousers for summer outfits

Some people say that men’s linen trousers are too casual for anything more than a beach vacation, but I’m starting to think they could be a great completion to many summer outfits. I’ve been seeing more and more stylish examples online lately that look both comfortable and refined. Have any of you found good ways to style linen trousers for men in more varied settings than just the seaside? I’m particularly interested in how they fare for hot summer days where you still need to look put-together. What cuts or colors do you find most versatile?
