I'm a sucker for simple web sites, and I generally think it looks great.

The only things that stands out at me as disruptive (warning, personal opinion ahead):

* Thick and bright white border on the images, maybe use a width/color closer to the style/color-scheme of the rest of the site

* Inconsistencies in image spacing from page to page

* On the wristbands page I would move all the text up before the images so it is easily seen, I almost missed it until I took a second look
