F-5XB... How many versions are there?

I'm confused by the pricing for the F-5XB bag... I've seen prices in the low-mid 50s ($US); then I've seen prices in the mid 80s ($US).

I've heard about different finishes and different numbers of pockets/ sections.

Is there more than one version?

Seeking clarification.

Thanks

Hello again...

Is the F-5XB Ruggedwear version available in olive? What is the colour of the strap for the olive bag? (Not too bright I hope.)

Also, what is the order number (code) for this bag.

In my neck of the woods (Ontario, Canada), the resellers seem unfamiliar with this product.

Thanks again.

Here's hoping for an answer.
