How many 12oz cans can it hold?
Is the Goldenrod color considered to be orange or yellow? I am seeing various shades in different pictures online.
What is the width and depth?
How many cans can this hold + ice?
Is this durable for construction & sitting in a hot truck for about 10 hours?
Do any coolers in your Unbound series float if accidentally dropped in water? I'm sure these weren't built to constantly be submerged, but am wondering if this would instantly sink if it went overboard while paddle boarding. Thanks!
