Perfect for wearing to bed, these matching tank and shorty sets are made from super soft modal which is sustainably sourced from Beechwood and is proven to be more than twice as soft as cotton. This natural fiber breathes with the skin making this set the perfect choice to wear all night. These feel amazing during a warm Summer’s night! They do fit small/fitted. I would size up in these. Made of 95% TENCEL™ Micro Modal, 5% Elastane.
