I have the Fly Butane 3 and matching pants. This set has removable liners. They are good down to about 45 degrees, With the liners out it is OK up to the mid 70s. Above that they are hot. I got this to ride in western WA. They are good in the rain. I think Spokane summer heat will need a mesh jacket. I plan to add one to my wardrobe by summer.
