I've happy wih 20years out of any gear depending on how much it's been used.
Surprised they didn't have a go at fixing it, or at least offer you a decent discount on a replacement, can't see them doing it for free but why couldn't they just cut 40% off a new one??
Got a macpac sleeping bag that is only 4years old and needs the main zip replacing... Will see how that goes this winter when I take it in
