I found these fabulous lightweight jeans from Coldwater Creek for an upcoming trip. I NEVER travel with jeans because they’re so heavy and bulky. These are completely different. They’re so light, almost as light as my favorite linen pants. They almost feel like poplin pajamas. They’re 90% cotton, 10% polyester. They have a loose fit, and I sized down. These are comfy enough to wear on the airplane. Currently on clearance for $24.95-$34.95.

Edit: I hand washed these pants and hung them to dry overnight. They were completely dry and wrinkle free in 12 hours.
