Store clercks are not allowed to ask what is  in your cart. That's why they don't want you to use your Rolser cart . I put everything in my cart while shopping and always empty  the cart at the teller and very obviously show them that nothing is forgotten in the cart.

Never have any problem. !!

The Mountain has 2 pockets , one on the flap and the second one in the back of the bag.

The Saquet has only one pocket on the flap. It doesn't have the buckle , the Mountain has. The frames are exactly the same as well as the contents of the bags.
