I recently put a hole in my Hestra 3-Finger gloves while skiing some trees. I'd always heard good things about Hestra's lifetime warranty and saw it described across the web as "super" and "amazing":
So I figured there would be no problem in fixing this as I'd only used the gloves about a full season before the leather gave way.
Now if you try to find the actual documentation for Hestra's warranty, it doesn't really exist. It's mentioned here and there that there is a lifetime warranty but no details are provided on any Hestra website.
After mailing in and waiting for processing, the warranty dept person had this attached in their email when denying my request:
Limited Lifetime Warranty:
Hestra guarantees our products against manufacturing defects and workmanship. It is at the sole discretion of Hestra Gloves to determine defects.
Exclusions of Warranty:
We will not warranty items against improper use, misuse, accidents, unauthorized modification or alterations, normal wear and tear, improper care or drying, negligence, damage, or if the item was used for something other than its intended use (skiing).
I don't think this information is available anywhere else and it's a pretty weak warranty overall. Sounds to me like they will only replace if a seam comes out immediately after purchase.
Just thought I'd provide a reality check to balance all these threads across the web on how great Hestra's warranty is. It's the least generous warranty I've dealt with thus far.
