I have bought 2 sets of these for the kids thinking they are bamboo viscose sheets based on the descriptions and pretty shocked to discover they are flax linens after getting them. (Yes I mean the descriptions are WRONG) While their qualities are not the best you certainly can't complain at this price, especially if you are after the smaller sizes which are not very common with linen sheets and often comes at a relative bad (comparing to larger sizes) price point. Catch have the full range of different sizes available and pretty good value if you wanna try out linen sheets.
I also got a spare Queen set when it was on sale for ~$150 but didn't post it here as I was not sure if it is also flax linen, which it is. It is now back to $179 which is also a reasonable price but just bear in mind it has been cheaper.
