I just got to ask, how did you tear your pants? Did you catch a sharp edge on your trailer or sled? Did you drop a knife on the pants and cut them? Did you run over the pants in the trailer with your sled and they got torn? BTW I or someone in my group have done each of these to items that I have had and not once have I even consider that to be covered under warranty. Maybe you are lucky enough to ride every day and have worn out the knees from riding so much in one year that they do not last more than one season and start to tear, and if this is the case I have no simpathy for you because you get to ride everyday. I just do not believe that the material just rips apart without some outside force causing the tear. Maybe it was a tree branch that caught the pants and cause the rip.
BTW I had a pair of bibs that I sent in 3 years after i bought them because the zipper was broken. They fixed it and yes I paid shipping. Best $6 i ever spent. The next year the other zipper broke and I asked if there was any waterproofing stuff because the rear end was starting to leak. Sent them in to be repairs and less than 1 week later i get a box from them and think wow they fixed those quick. I opened it up and guess what i find? A BRAND NEW PAIR OF THE NEWEST BIBS IN THE BOX. All I was asking for was some waterproofing and the zipper to be fixed and I got brand new bibs. I think they have a customer for life in me. Oh yeah I do have the boots and the first year I had them my friend pushed one of those sleds to carry all your stuff into a cabin behind the snowmobile, you know the old school metal ones, into my foot and put a hole in my boot. Yeah i asked what they could do but understood that it cannot be a warranty claim because it was not a defect in the boot. It was an accedent and $%#$ happens. So now I have some shoe goo on it and deal with it. Still is works just fine. No leaks.
Maybe check the sizing of the pants. If they are too small, the stiching is coming apart because you are stretching it out too far. You are not as thin as you used to be. I know how that feels. I have been wearing size 34 pants for 2 years now because I can't admit that i should be a 36 instead of the 32 i used to be. I keep telling myself that I am going to work out and get back in shape so i can fit back into my pants, but lets face it I probably will never be that small again and just need to buck up and get new pants. Come to think of it my bibs are a 32. Maybe I should get off this dam comuter and go work out. Like that's going to happen.
Don't get offended by this last part. It's all in good fun.
Now go have a and watch some sledding videos.
He didn't send them in to get the rips repaired. He sent them in to get the zippered repaired and they denied the claim (according to the poster) because they were ripped.
That being said. I've had good luck with my Klim stuff so far. Had some bibs for 4 seasons before I ripped them (ripped after being ejected from a cranky snowmobile) and a jacket for 5 or 6 seasons now with no issues.
