I would love a clever visual image that captures the brand, but I'm thinking this may be as simple as a typographic treatment.
I've created a template (attached) that I'd send off to a velcro manufacturer. I'll print the logo on a 1" x 4.5" stretch of fabric, so, it should fit there and look good. The fonts used on the template is just a placeholder.
The white water kayaking sport is aggressive and edgy, so the logo/typography should reflect this. Bold and risky, but humble.
This is a product logo for a company named "River Spanked Products". I'll need a logo for the company too, but I'll submit for that separately at a later time. I mention it just so you get an idea for the overall brand. River Spanked Products are all "River Tested", meaning they're able to endure the turbulent river environment. Though the river is our playground, it is quick to "spank" us to remind us who's really the boss.
I'm also attaching a logo for Betty Designs, who's tagline is "Bad Ass is Beautiful". I love that! They capture that attitude perfectly in my opinion with the skull and butterfly cross-bones. I'd love something that captures and conveys the attitude so succinctly.
