Great comfortable jeans.  More comfortable than some of the expandable waist trousers I've worn.  I tried the Liberty Blues initially, but they were a bit on the smaller sized than I thought and the material felt almost like sweatpants.  These jeans actually feel like a durable demin, but with enough stretch for comfort.  They should last many years going through the washer & dryer since there's no elastic tab in the waist to get fried.  Great work or casual pants.
