So the window and inner hook points delaminated on our 10 year old Trango 2 tent. I asked Mountain Harware UK dostributor if they could sell us a replacement. Due to recent warehouse changes they said they couldn't as all stock had been shipped back to America.
So I thought why not try my luck, I messaged MH America with the same query. 2 days later there is a brand new Outer/rain fly on its way free of charge!!
Tbh the adhesive on the windows on the new outer is already cracked and delaminating, though the window is at least stitched in (don't look a gift horse in the mouth?). A quick blob of seam grip should reinforce it for a decade or so.
