Copper River proudly insists that this is a bag that "you can hand down to your kids and they can hand down to their kids" - it's clear that they really mean it. The 4-5oz thick leather (approximately 0.06-0.08") will handily stand up to all manner of abuse, and the two heavy-duty solid brass clasps will securely fasten the all-leather matching shoulder strap. The rest of the hardware is also solid brass, a metal that naturally features germicidal and corrosion-resistant qualities.
