BaggalliniWomen's Triple Zip Small Convertible Crossbody Fannypack Belt Bag-Lightweight Water-Resistant

Q: Does it hold an iphone 6 plus?

Yes. In the largest compartment I have my checks (no cover), a small plastic organizer with photos, and my LG G3 which is comparable in size to the Samsung Note 4 & iPhone 6+. I have a cover on it, too, but it's the kind which only covers the back, not both front & back of the phone. In the middle compartment I have my rx sunglasses (no case) & an inhaler. These are the items that usually bump me up into a bigger purse.

Q: What are the dimensions?

For anyone else curious, from the product description info - Product Dimensions: 8 x 6 x 2 inches; 0.35 Ounces

Q: is there a way to purchase a strap for the baggallini classic trip bag

it came with a strapbut if you want to replace it -- it is skinny you could find one on another bag a

Q: If the bag was empty would it smoosh down flat? Or would it still have depth to it?

Since this has no hard edges or sides to it, this would be nearly flat - supereasy to pack if that's what you're planning. But it holds a ton of stuff!!
