When I find that I'm getting lots of views on a product, but no sales, I always take a close look at my photos and description.
In your case, I looked at a couple of listings and still had lots of questions: what do the bags look like inside? how much can they hold? (could you show a photo of some common items in the bag?) how long are "extra long" handles? (does that mean I can put the bag over my shoulder? could you show someone carrying the bag?) is the pocket zipped or snapped shut? (is is possible to show a photo of the pocket?) is it machine-washable? will it shrink or fade?
You get the idea. :)
If customers are *very* interested, they might email and ask you to answer the questions. But some of them will just move on to another shop.
