They OFTEN have a little elastic which is also awesome for me!! The more the better actually. They're in sporty adventure type stores. Also, I just bought a really nice pair of Nygard brand stretch pants with a side zip and an elasticized waist. They feel HEAVENLY! You can likely find Nygard in places like Sears, Macy's etc. I don't think it's a Canadian brand.
