I have a couple pairs of zipoffs but never wear them. I get sunburned to easily and don't like the fact I have to take off my boots, and the zippers are designed by someone who doesn't hike. I really like the Kuhl Kuhldry jeans they are priciy unless you find them on sale but I've had my two current pairs last through 3 years of abuse and one just finally developed a hole. They dry in a flash no matter what the weather is they absorb abuse like iron and resist stains. They are light enough and breathe well enough to wear all summer even when the temps push into the 90's.
