Super sturdy, 100% Nylon, Large capacity bag. The orange/rust bag has a melon yellow interior; the black has a taupe interior; roomy interior with multiple compartments. Measures approximately 12x6.5x16in., D- 11in. Purchased both of them pre-owned; both have signs of wear and tear BUT they are in pretty good condition considering. The orange one arrived to me with evidence of gum/candy remnants in one of the interior pockets. It's an orange-y/rust/vibrant color. I've washed both, and they are a great find for anyone looking for a great deal on this style. The orange/rust one also seems a bit faded but, in my opinion, that only adds to the vintage appeal!
