The lumber used to build Loch sunglasses has been resting under the depths of the Great Lakes for up to 200 years! Massive timbers are literally dredged up from the depths, dried and milled into a material boasting a unique quality and character exclusive to water-reclaimed wood. This water-reclaimed wood was originally harvested by our settlers up to 200 years ago during the logging boom and floated down the fast flowing tributaries to the Great lakes. Not all the logs made the journey and sunk to the bottom. The old-growth, water-restored lumber in Loch sunglasses began growing between 1000 and 1500 AD making the wood in your sunglasses between 500 and 1000 yeas old!
