The sheets feel very smooth and comfortable - as expected from the thread count. However the material is very light weight so have concerns about long term wear. In addition the finishing on one of the pillowcases was poor. Have linen from Costco (600 tpi - similar price like for like) and White Company (more expensive). Quality considerably better from these other two suppliers. Unfortunately Costco don't offer a super king option. All in all it was a satisfactory balance between cost and quality but only worth it with the extra seasonal discount that applied; otherwise Next might have been better option (similar price without extra discount and felt better quality and 600 tpi).
