I wanted to let you guys know about a killer sale I found on Prince Charlie jackets with included vests (waistcoats). The company is Burnett's and Struth in Ontario, Canada, and I personally vouch for the quality of their work. The "tank" and jacket I got from them are superb!

Sizes are limited, but it's a good deal if you find one that fits. $200-250 CAD.

If you scroll to the top of the page, you can find really good deals on "tanks" that are pre-made, so they're selling for really good prices too.
