Nikon D90 camera bag - Matin Leonard adventure 320?

I'm getting my Nikon D90 in less than a week and have been searching for bags for the past while;
i really like this bag, however i want a second opinion because i can't find any reviews- in terms of quality, durability, how useful it will be etc.

& how does it compare to this (quelity etc.) - http://products.lowepro.com/product/SlingShot-202-AW, 2192, 4.htm

Construction quality looks about equal. Material is different, the type of bag is different. A slingshot is comfortable to wear
