I received another order today, and am always amazed at build quality of Tom Bihn products. The seams, piping, zippers, attachments, and materials are superb. The new Side Effect is outstanding in construction, and surely must be labor intensive for the crew. My Co-Pilot surpassed all expectations, even being larger than anticipated. They should last 100 years. My sincere thanks go to Tom and his entire crew for sustaining the highest quality standards I've ever seen in travel gear.
