"While we go to great lengths to ensure that every Orvis wader is built to our high quality, waders will eventually wear out and fail, much like the tires on your car.
If you are not satisfied with your waders at time of purchase or if they fail for any reason within the first 60 days, we will replace them or refund your money, no questions asked. Beyond that, waders that fail due to manufacturing issues or defects will be repaired, replaced or refunded, at Orvis's discretion, free of charge.
Damage or failure from normal use, wear and tear, or accidents is not covered under our warranty. There are several options and resources available to help get you back on the water. Each wader comes with a repair kit containing all the necessary items to perform basic repairs. Detailed instructions and links to purchase additional supplies can be found below."

Read the warranty and other info before you start speculation on companies...
