We warranty products we sell to be free from manufacturing defects. GOSSAMER GEAR DOES NOT WARRANTY PRODUCTS AGAINST MATERIALS OR FABRIC FAILURE DUE TO DURABILITY ISSUES. If you are unwilling to accept the limitations of the lighter materials used in our products, do not purchase them, or return them upon receipt in accordance with our return policy. Please note that due to use of extremely lightweight materials, the G5 and Whisper packs are sold with NO WARRANTY.
