I think there's some confusion about whose "lifetime" the product is warrantied for. It sounds to me like you're interpretting it to be *yours* but I believe it refers to the product and I also believe that REI can, at its discretion, decide how long a reasonable lifetime is for its products.
I agree with others who think your shorts are well within its "life expectancy" and should have at least been replaced with a new pair.
I think 7 years of regular use for CF hiking poles is pretty much near the end of its life.
I think your binoculars have lived a full life. Not saying that you should expect 20 year-old binocuars to fail or that many don't, just that I don't think you can point to its condition after 20 years and call it a "manufacturing defect".
That said, I recently had a pole fail on an REI tent that I've had for maybe 3 years (i.e. purchased before the policy change) and when I contacted my local store about where to get a replacement — and I never mentioned or even hinted that I thought this was a warranty issue — the salesperson definitely took a VERY defensive attitude. Basically started lecturing me about how I "must have" mis-handled the poles. Had me pretty steamed. And this was the store that practically tore a Marmot jacket off my husband when a salesperson noticed that he was struggling with the zipper and insisted that he take a replacement AND a partial refund because the jacket was now on sale. We'd gone there to buy my son a jacket… and came home with a new jacket for my husband and got my son's for "free" because the refund covered the cost of his.
Things have definitely changed.
