All product life span is improved with hand wash and lay flat drying, but if you don’t have the ability or time, delicate wash in your washing machine is fine and low tumble in the dryer. This also extends the life of your prints.
High heat can damage the spandex and break it down or lose the retention quality.
For any technical fabrics, fabric softeners break down the performance properties. Stay away from added fabric softeners, in general.
For more details on things like our water activated, glow-in-the-dark prints, swim, Solarmesh, etc. please see our Wash & Care Guide.
