of course they aren't worth it. they have a flexible zipper topped on at only $299 which is similar to my $9.95 walmart special. :)
other Yeti knock offs are half the price and probably just as good. I mean we aren't talking rocket surgery or brain science here. buy a coleman, glue styrofoam sheeting to the inside walls, and for 10% of the cost, have equal protection.
IMHO Yetis are ego boosters, not unlike Rolex watches and other pretentious nonsense.
my daughter got me a Yeti travel mug for Christmas, works great, probably better than most of my other ones but $39.00????????????
