I finally made the phone call to Eddie Bauer and I asked what is the difference between Chino and Khaki.As one who lives on both sides of the world, I found that the heavy Chinos are too hot for a hot climate. I had never looked into the Khakis because they were described as "Dress Pants." I am pleased with my Khakis as the material is moderate weight and these Khakis should be purchased for summer wear and the Chinos for winter. I use my pants as casual pants for shopping, walking, visiting family/friends, etc.As one who lives in the hot climate overseas, I will be stocking up on Khakis. It should be noted that I own several pairs of Chinos and I'm very happy with the wear and the wrinkle free material that with stand many washings. I've been wearing Eddie Bauer's Chinos for approximately 15 years.One final note: as an older man, my weight fluctuates and that makes the stretch capability of the waist critical and is the main reason that I'm comfortable ordering these pants online from Eddie Bauer.
