Being a big fan of the VSSL JAVA Coffee Grinder, the folks at VSSL send me a pre-release version of their new VSSL insulated flask last October.

Much like my VSSL coffee grinder, the flask is very well made and shows exceptional attention to detail. This is not some cheap piece of camping gear you buy at your local hardware store, but the kind of product that will likely last your lifetime, or more! Made of stainless steel, the flask holds 8 oz of your favourite liquid, either hot or cold. Since it’s double wall insulated, it’ll maintain the contents’ temperature for hours. In terms
