I got my new stihl chainsaw trousers two weeks ago and sent them back after two days due to them being full of holes!
I've heard today that stihl will replace them, no worries. (there would have been some strong words if they hadn't) They are interested in why they failed and said to carry on with the new pair as usual and let them know how I get on. Basically I ripped the leg on a tiny stub while slipping un stylishly down a branch. I thought to myself, "that was stupid better sew it up when I get home."
Got home and took them off and noticed that the seat had worn through, not ripped but worn through after two days!! The seat is single layer, whereas the SIP's have a reinforced seat and mine aren't worn through after 9 months.
If anyone in the UK has trouble with these trousers they should send them back ASAP, stihl need to know whats going on. It is of course possible that this was a one off unfortunated occurrance. My new ones arrive tomorrow so we'll see.
