I have an Olympia AST jacket that I am very fond of. Would be much more fond of it if it was actually waterproof, but thats another thread. The zippers in the arms have split, and are in need of replacement. Does anyone know of a competent shop in the Greater Toronto Area that could make such a repair? I should look at replacing the whole jacket, but it fits and feels great, so looking for a repair place if I can get it done for reasonable costs. Thanks.
