Care Instructions

Wash before first use on cold with like colors

Tumble dry low

Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.



Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.
