Sleeping Hills 3M Microcell All Season Moisture Wicking Lightweight Sheet Set vs Washed European Linen Core Sheet Set: which is safer?

Where these two actually differ

• We flag Formaldehyde-based finishing resins, Undisclosed proprietary coating chemistry (3M Microcell), Microplastic shedding from polyester fibers and Coating degradation and loss of water/stain repellency on the The Gray Barn and not on the Brooklinen.
• We flag Azo dyes and heavy metal colorants and Fiber shedding or microfiber release on the Brooklinen and not on the The Gray Barn.
• The The Gray Barn is Polyester blend with 3M Microcell moisture-wicking treatment where the Brooklinen is 100% European linen, washed finish, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
