Machine wash cold with like colors on the delicate cycle, using a small amount of a mild liquid detergent. Skip fabric softener, bleach, and stain boosters, which are all hard on the fabric.

We recommend hanging to dry. Machine drying can hinder the longevity of the leggings and may reduce the elasticity of the spandex over time. The heat from the dryer may also cause pilling of the fabric. If you need to machine dry, do so on low heat.

Tencel Lyocell is a plant fiber, so it does best with a gentle liquid detergent and nothing else in the load.

Look for a liquid rather than a powder, with no cellulase, no washing soda (sodium carbonate), no oxygen bleach or brighteners. A few we like: Seventh Generation Free & Clear, 9 Elements Unscented, Attitude Unscented, and Heritage Park Silk & Wool if you want the gentlest option.

What to skip: powder detergents built on washing soda, anything labeled sport or activewear with an enzyme blend, oxygen boosters, and stain treatments added into the wash. These can lift color and roughen the surface, usually showing up first at the inner thigh and seat.
