Exact same product (just different packaging and flavor cartridges included), two dollars and eleven cents difference. *shrug*
tangental note: I've been using Cirkul for years and I approve of the product, have had three of the four flavors shown (not a fan of 'mixed berry' anything), and do not own a plastic bottle because the lids fit thrifted double-wall metal flasks -- larger volume and insulation are my jam. FYI their website offers a limited-time flavor every month and the one that dropped yesterday is Glacier Berry... nope, thanks.
