S4Gear was originally started by some of the same people I worked with at BowTech. Gene Shands and I put together a really slick website that mirrored the aesthetic and functionality of the outdoors accessories that S4Gear was manufacturing. As S4Gear grew we continued to add facets to the site. Some of their products were aimed at several, distinctly separate markets (bird watchers and hunters, for example), so we developed the site into four sub-sites that ran on one backend. This helped to organize and maintain content that was sometimes available on all four subsites, sometimes only on one, and ensured that bird watchers didn't have to see pictures of people holding dead turkeys!
S4Gear has since changed ownership and their website has moved on, but the original site remains in my memory as one of my favorite web projects.
