Tested in IE6 5k modem 800x600. LOads reasonably fast. Slightly too wide for 800x600. Might be nice if the menu at the top rolled over like the links. Otherwise, a very nice design. Good luck with it.
A really attractive and fast-loading site.
I think tho you might consider making the banner not quite so high, even the the photos are lovely. As is it is in my browser (MYIE2 at 1024x768) at least half the visible screen when the page loads is banner and all the photos and information are "below the fold". This would bring the navi-menu into view as well. As it is I can only see the first 4 of twelve main buttons. I would suggest the banner be about half the height it is now.
On the start page I don't see why you don't link those product pix to the appropriate pages. If that vest is exactly what I want, I can go straight to it.
The structure from the "category" menu buttons leads in every case to a sub-level with another page where the reader must choose again. When there are more subcategories, that makes sense (and on these pages I would put thumbnail pix for each sub-category). But several of these buttons lead to a sub-category page with only one choice and the reader has to click again. I found that a little irritating and perhaps you ought to eliminate this extra step.
The site is attractive and fast. Best of luck
