Bare may give a lifetime warranty on the seams and workmanship, but I always felt such "lifetime" warranties are a bit disingenuous. Most suits don't fail due to manufacturer defects (which would be covered) except in the first few years, where pretty much ALL drysuit manufacturers would fix them under warranty. After a few years, any seam failures are likely to be a result of wear and tear, which is NOT covered under warranty, including Bare.
DUI has a 7 year warranty on everything except the zipper and valves, which is pretty good (one year on that). Not quite as good as Bare's, no, but then, two things to consider:
1) As I said above, covered "defects" generally don't happen after 7 years of service... they're generally excluded as wear and tear problems.
2) DUI's warranty repairs are done right here in the U.S. (international peeps can ignore that benefit) instead of having to ship the drysuit across the border to Canada.
And then there are zip seals. No one else offers zip seals. That's a BIG factor in my decision, personally.
I can't find any info on whether Bare warranties the zippers and valves, so far. The only info online is the text quoted in the post above... leads me to believe they're not covered. In that case, DUI's one year coverage, limited though that may be, definitely wins for that very expensive item.
Just to close the loop on this, Bare's customer service responded to my inquiry about their warranty:
The Valves, Seals or Zippers are not covered under warranty. Having said that, if something goes wrong with the suit after diving with it for the first time, then we would take a look and make a determination, however no guarantees that it would be covered under warranty. It would be done on an individual basis.
Material defects means that if the stitching came apart, or the seal tape came apart not due to the consumer's fault, and it was found to be a defect in workmanship or materials, then it would be covered.
So Bare will cover manufacturing defects for life. You know, those ones that crop up new and unnoticed for the first 7 years you owned the suit.
They do NOT cover Valves, Seals or Zippers, outside of maybe if there is a spectacular failure from the first time you get your suit wet.
DUI "only" has a SEVEN year warranty on those manufacturing defects. They also give a one year warranty on valves and zippers, which Bare does not cover at all. I believe they also have either a 30 or 90 day warranty on their seals (can't recall which) but I doubt it would cover the usual accidents that tear seals... still, better than Bare.
I'm going to have to give the warranty edge to DUI, in my book, in spite of Bare's "Lifetime" warranty.
