The green linen trousers are one of the coolest things in the store IMHO. I wouldn't really have thought they'd look so good and be so versatile until seeing them in person, but you could have a pair of those and a pair of beige linens and be pretty set for the whole summer.
I am debating between the greens and the dark brown. Clearly I missed out on the beige twill. The green look very nice though, and I imagine that they are quite versatile.
