I love our Brooklinen sheets! Haven’t found towels I love yet though. We’ve had Restoration Hardware towels and they’re soft and thick but didn’t really hold up that well.

We have linen sheets, and I love them. Our first set was Restoration Hardware, but they ripped (which, in retrospect, is super annoying. They were expensive! Although they did last, like, five years) so now we have some from Caspar. I like them because they don't have the freezing cold feeling you get from cotton sheets in the winter, but they're not as warm as flannel.

@Jess1483: this is my area, I work with textiles and I love nice things
Towels: the best I've found are wonderfully not-pricey from Target, Fieldcrest Reserve. (Had to look it up and they're on sale today!) Many friends and guests have asked me what they are and are really surprised that they're so inexpensive. We've had ours for almost two years and they're holding up great.
Sheets: I think what people like in sheets is pretty subjective (ike mattress preference) but I like a crisp, smooth, heavy-weight percale--the best I've found is the percale from Casper, which are super nice quality and the fitted sheet is perfectly snug. I tried Brooklinen and the fabric didn't feel substantial enough for me, but they're still nice. Peacock Alley is a classic brand that you can find at TJ Maxx etc and they're usually really nice.
Bedding: If you like linen for duvets and shams, Parachute and Matteo both are very nice but a little spendy. I've also had stuff from West Elm that holds up decently.
ETA for down comforters that last forever: LL Bean

I really love our Wamsutta sheets from Bed Bath & Beyond. The fitted sheet never comes off and the sheets are soft and last many years.

We have three sets of our sheets, love them! Pure Beech Sateen from Bed Bath and Beyond. They are smooth and super soft and have held up well. 7 years in and one set has a rip on the seam of the fitted sheet but everything else is good as new.
