What's Covered Under Warranty...And What's Not

Covered

All Big Agnes products include a Limited Warranty against manufacturing or material defect. Items will be repaired or replaced at the discretion of Big Agnes. If replacement product is not available credit will be given for the original purchase price when returned with a receipt.

Not Covered

We do not warranty products damaged from normal wear and tear, alteration made by owner, misuse, accidents or damages caused by uses other than intended.

We shall not be liable for any consequential or incidental damages of any kind. This includes, but is not limited to, damage or loss of other property because of defects in our products. Some states do not allow the exclusion of consequential damages, so the above exclusion may not apply to you.

What is Normal Wear and Tear?

Well-loved gear will develop battle scars. Gear tears, zippers retire, poles snap. When this happens, we will do everything in our power to refurbish and repair your gear to get you back out there. We do so as inexpensively as possible to encourage keeping gear alive rather than in a landfill.
