Defects in materials or workmanship are uncommon and almost always evident while the product is still new. If something goes wrong and it's our fault, we'll fix it for free. Repairs due to normal wear and tear or otherwise not our fault will be done at a reasonable charge. Keep in mind that daypacks, messenger bags, and briefcases are often subject to extreme wear in everyday use: do not expect them to last forever. Only true-love lasts forever! You can expect a TOM BIHN product to give years of hard service.
