I recently purchased new North
sails from the loft in
New Orleans. The zipper on my
mainsail cover gave way and
water stood in the folds of the sail for some time and resulted in some yellow staining. I took the sail back to North. They shiopped it to a lab back east to try to determine the cause of the staining to no avail. They then promptly replaced my sail. I'm a North customer for life.
