WiWi Women's Bamboo Nightgowns Knit Sleeveless Sleepshirt Lightweight Sleepwear, Prussian Blue, 4X

The price for this item lurched from $17 to $26, rounding up to the sacred marketing penny, of course. The nightgown is a smart design, very thin and comfortable, arrives well packaged. The specific limited colors offered, not so great. A big issue for me is that, especially regarding price increase vs. quality, the chemicals used to make rayon or viscose bamboo fiber include carbon disulfide and sulfuric acid -- harsh chemicals that might possibly wash out of bamboo fabric but bad environmentally. If the process to make bamboo clothing is non-toxic, then natural enzymes are used instead of harsh chemicals to produce bamboo linen with a process called mercerization; this makes a fabric specifically called bamboo linen. Clothes and fabric made from Bamboo linen would certainly be a marketing selling point thus highly likely stated in a posting description or touted in an advertisement. This nightgown is stated as being 95% viscose from bamboo.
