I'm not the pants type anymore, you see me more in skirts and dresses. But a pair of nice wide linen pants are definitely great for the transitional period when it is still a bit chilly in the morning but is already getting warm during the day.
The pattern is from the pants kit. The zipper is in the back, I've never seen it in retail clothing, but it works great. You have a nice long relatively straight edge where you can insert the zipper. You can also set the zipper in the side seam or in the front, if you prefer that.
